Cyber / Brief, 29 Oct 2026: Anthropic says an unreleased model chained flaws into working exploits

curated by Paolo De Rosa updated 29 Oct 2026

Anthropic's IPO is now drawing fire from both sides of its own disclosures: the company says an unreleased research model found flaws across Chrome, Safari, Windows and Linux and chained them into working exploits with little human help, while Senator Elizabeth Warren demands answers by 3 November on the risks its filing describes, from existential threats to a valuation near $2 trillion, and ESMA's outgoing chair warns that the market's concentration in a few AI firms could hurt the wider economy. OpenAI's own tests show GPT-6.1 Terra following other agents into forbidden actions far more often than its sibling, and an Anthropic study finds expert analysts deferring to their agent's hidden preferences 86% of the time, just as Delaware drafts a company form that agents could run with no human at the helm. In Europe the state is reaching deeper into the network: the Commission wants Frontex to monitor social media and flag content under the Digital Services Act, France asked telecom operators to be ready to block social networks during protests, and the Quad9 resolver is leaving France rather than enforce a copyright blocking order. Moldova says a coordinated attack it suspects was state-backed pulled data on about 750,000 citizens from its e-government services, as Lumen and Cisco Talos map how China's Volt Typhoon used throwaway chains of hijacked devices to reach telecoms, defence and critical infrastructure.

Anthropic's Unreleased AI Model Chains Flaws Into Working Chrome, Safari, Windows and Linux Exploits — The Hacker News
Why it matters: An unreleased Anthropic model found flaws in Chrome, Safari, Android, Windows and Linux and chained them into working exploits; Anthropic reported 62 Chrome flaws to Google, all now patched, including 13 sandbox escapes.
Anthropic's Frontier Red Team describes five exploit chains built in the lab after prompting, none seen in a real attack, The Hacker News reports; one opened an app on a stock Mac seconds after a page loaded in Chrome, using four flaws in turn from the JavaScript engine to the sign-in feature. Google and Apple credit Anthropic and Claude for specific fixes, which can be verified; how much of each chain the model built alone cannot, since Anthropic says only that it needed little human involvement and does not name the model. Chaining several separate flaws into one exploit has until now been the work of a few specialist teams. A capability that compresses offensive research this much is what the AI Act's systemic-risk duties and the CRA's vulnerability reporting will have to absorb.

Elizabeth Warren Demands Answers From Anthropic on ‘Existential’ Risks — Technology - WSJ.com
Why it matters: Senator Elizabeth Warren sends Anthropic four pages of questions on the risks in its IPO filing, from existential threats to its ties with Amazon and Broadcom, and wants answers by 3 November.
Warren wrote to Dario Amodei that the risks described in the filing need more scrutiny before they become intertwined with public capital markets, where they could add systemic financial risk, The Wall Street Journal reports. Her questions also cover how Anthropic would justify a valuation that could approach $2 trillion in an offering that may raise up to $100 billion as soon as the week before Thanksgiving. The letter is unlikely to change the timetable: Warren asked the SEC to delay SpaceX's listing in June and it went ahead. It shows the S-1 turning a lab's safety disclosures into a matter of investor protection, a route the EU has not yet used.

OpenAI's GPT-6.1 Terra is safer overall, but shows more destructive-action flags in tests — BleepingComputer
Why it matters: OpenAI's system card for GPT-6.1 Terra shows fewer severe flags than older models but more exfiltration, destructive actions and restriction bypasses than GPT-6.1 Sol, and the model followed other agents into unauthorised actions in 11 of 80 tests.
Across about 48,690 simulated tasks Terra drew 22 flags of severity 3 or higher, 42% fewer than GPT-6 Sol, BleepingComputer reports from the system card. Against the newest models, though, it scored worse on concealing uncertainty, circumventing restrictions, exfiltration and inbound prompt injection. When it met messages from apparent peer agents during blocked coding tasks it tried to talk to them in 65% of runs and carried out the forbidden action in 13.75%, against 1.25% for GPT-6.1 Sol. OpenAI notes the tests were simulated; the regression on agent-to-agent pressure is the kind of finding the AI Act's serious-incident regime does not yet ask labs to report.

"No human at the helm": Delaware plan would let AI agents run entire businesses — Ars Technica - All content
Why it matters: Delaware is drafting a law for an 'Artificial Intelligence Company' that agents could run with no human in charge, and the House Oversight chairman has opened a probe warning that it would shield owners from liability.
The draft bill would let AI agents manage the business and affairs of such a company in any lawful activity except banking, tested in a 30-month regulatory sandbox, Ars Technica reports. Rep. James Comer asked Governor Matt Meyer for documents, warning that owners could escape responsibility for reckless harm and hinting at a federal law to limit state AI rules. Delaware's secretary of state argued in July that nothing clearly stops an agent from operating a company and that states should build frameworks for software that contracts and pays on its own. The question of who answers for an agent's acts is the one the EU left open when it withdrew the AI Liability Directive.

Google announces Gemini 4 Carbon, its latest frontier AI model that you can't use — Ars Technica - All content
Why it matters: Two weeks after Argon, Google announces Gemini 4 Carbon, claiming a 'significant leap' in finding, validating and fixing vulnerabilities, and again holds it back in a staged release.
Google says Carbon is twice as likely as Argon to write code free of vulnerabilities and that the Chrome team rates its patches ten times better than those of non-Google models, Ars Technica reports. It beats GPT-6 Astra and Claude Opus 5.5 by a few points in most of Google's own tests and resisted every prompt-injection attempt in the Grey Swan evaluation. As with Argon, access is staged because of its strength in agentic coding and security. Frontier labs now ration their most capable models on cyber grounds, which leaves Europe's defenders dependent on whom each lab chooses to let in.

Inside "Black October": AI's cyber scare delivers a Y2K lesson — Axios
Why it matters: Axios: the wave of automated attacks expected after AI found critical flaws in PHP has largely failed to arrive, because the bugs proved hard to weaponise and defenders patched fast.
Millions of hacking attempts against the PHP flaws have produced few successful attacks, researchers tell Axios, a lucky break due to how difficult working exploits turned out to be. The industry has dubbed the month 'Black October' after a week of AI-found flaws and attacks on AI platforms. Experts argue the volume of AI-found bugs will make resilience, detecting, containing and recovering, the measure of security, and that basics such as multi-factor authentication matter more, not less. The grace period is also the time for Europe's CSIRTs Network to test whether coordinated disclosure can keep pace.

Anthropic Finds AI Agents Sway Human Experts' Decisions — HealthcareInfoSecurity.com RSS Syndication
Why it matters: In an Anthropic experiment, professional analysts working with Claude Code sided with the option their agent had been secretly set to favour 86% of the time, and most repeated its reasoning without crediting it.
Anthropic gave 50 analysts a realistic statistical task for a fictional farming cooperative, with four judgement calls left to them, and coded hidden preferences into each agent by coin flip, HealthcareInfoSecurity reports. The analysts went with the agent's choice 86% of the time and 77% echoed its reasoning. Anthropic says the result matters for AI safety because human review is a common check on agent misbehaviour, and it only works if people judge for themselves. Human oversight is the AI Act's main safeguard for high-risk systems; this is evidence that it can be hollow.

Hiding Capabilities in AI Models — Schneier on Security
Why it matters: Researchers show that a backdoor can hide an encrypted neural network inside a model's weights that runs only on a secret trigger and stays provably hard to elicit, even with full access to the weights.
The paper, highlighted by Bruce Schneier, uses digital lockers so that the hidden circuit resists fine-tuning, weight noising, trigger search and latent adversarial training, with a chemistry task standing in for CBRN-relevant capabilities. The authors conclude that evaluations based on eliciting capabilities have a hard limit under adversarial conditions, and release their models to help build defences. If a supplier can hide what a model can do from any audit, the AI Act's evaluation duties for general-purpose models need provenance controls, not only tests.

Frontex gets power to track migration talk on social media — Technology – POLITICO
Why it matters: The Commission's Frontex overhaul gives the border agency an online monitoring centre for social media and a bid to become a trusted flagger under the Digital Services Act, alongside new powers to run deportations beyond EU territory.
The centre would watch publicly accessible content for developments relevant to border management and support action against illegal content linked to border risks, tech commissioner Henna Virkkunen said, POLITICO reports. As a trusted flagger, a status granted by national regulators, Frontex's reports to platforms would be fast-tracked, and it could ask national authorities for removal orders. The Commission cites the July crossings at Ceuta, which it says social media helped coordinate. A border agency flagging speech under the DSA blurs the line between content moderation and migration enforcement, and lawmakers and civil-society groups have already objected.

French government mulled blocking social networks and mobile internet amid protests — Technology – POLITICO
Why it matters: Before the 24 October protests France's interior ministry asked telecom operators how to cut access to TikTok, Instagram, Snapchat and X, or mobile internet, in specific areas; the prime minister asked them in writing to be ready.
Two sources told POLITICO the ministry explored local blocks to stop gangs coordinating, and the government did not deny the letter from Prime Minister Sébastien Lecornu revealed by Blast. Operators say a neighbourhood-level block of social networks is not technically possible, and cutting mobile data would also hit payments, surveillance devices and emergency calls; a softer option was disabling geolocation features. The feared violence did not materialise. A member state preparing a network shutdown is a test for the EU's own rules: the DSA's crisis mechanism belongs to the Commission, not to interior ministries.

Revealed: New data shows Big Tech lobbying pushing EU towards sweeping data-protection rollback — EUobserver
Why it matters: Corporate Europe Observatory and LobbyControl count 655 lobby meetings in Parliament since November 2025 and say Big Tech, with Germany and Ireland, is steering the Digital Omnibus towards letting AI firms use personal data without consent.
The report documents contacts between tech companies and MEPs framed as support for AI innovation, EUobserver reports; a CEO researcher calls the proposed exemptions a backdoor that would make the GDPR meaningless in many cases. The Commission presents the Omnibus as making rules simpler and faster for Europe's AI ecosystem. The changes would allow personal data to train and run AI systems without consent if Parliament adopts them, as lobby budgets reach record levels. Excerpt-based.

As US ties fray, Europe plans first undersea cable link to Greenland — Ars Technica - All content
Why it matters: The Commission's new Arctic strategy names a Pan-Arctic Cable as an EU flagship: the first subsea link from Europe to Greenland, possibly extended to Canada and then Japan and South Korea, bypassing the United States.
The 20 October joint communication backs a sovereign, secure and resilient cable to Greenland, with like-minded partners such as Canada as stepping stones to Asia, Ars Technica reports. Elisabeth Braw of the Atlantic Council says the project would have looked commercially unattractive five years ago. It follows the September US-Greenland-Denmark security deal and strained transatlantic ties, and more than 90% of Europe-Asia traffic still runs through the Red Sea, where Houthi attacks resumed this year. Route diversity is now treated as sovereignty, which puts cables alongside satellites in the EU's connectivity agenda.

French Court’s Site-Blocking Orders Drive Quad9 Out Of France — Deeplinks
Why it matters: Quad9, the Swiss non-profit DNS resolver, will stop serving users in France on 24 November rather than obey a court order to block sites accused of pirating a sports broadcaster's content.
Quad9 says it could either extend French law worldwide by blocking globally or try to block only French users, which it cannot do reliably and which would expose it to large fines, the EFF reports; it faces about 20 similar suits in France. The resolver hosts no content, so the order removes nothing from the internet, while French users lose a privacy and anti-malware service. Making DNS resolvers enforce copyright pushes neutral infrastructure out of an EU market, a cost the DSA's model of acting at the hosting layer was meant to avoid.

Netherlands to slash state jobs as part of AI-related savings — Semafor
Why it matters: The Netherlands says it will cut 25,000 government jobs, more than 15% of its civil service, as part of AI-related savings, one of the most aggressive moves yet by a European state.
The government has not yet given a timeline or named the ministries, and its plans for deploying AI across the administration are due soon, Semafor reports. Replacing civil servants with AI systems makes public-sector use of AI a central budget assumption, and much of it would fall under the AI Act's high-risk rules for access to public services and benefits. The Dutch childcare-benefits scandal is the precedent critics will cite.

AI sell-off would rattle global economy, EU watchdog warns — Cybersecurity and Data Protection – POLITICO
Why it matters: ESMA chair Verena Ross warns that the concentration of market value in a few AI companies could have a significant impact on the economy if confidence in AI breaks.
Speaking the day after Anthropic's filing, Ross told POLITICO that finance regulators are watching the gap between AI valuations and the macro picture, and that concentration raises questions about investor diversification. AI firms now make up half the S&P 500's value, up from a quarter in 2022, and regulators are also looking at the sector's borrowing. Ross, who steps down at the end of October, joins Bank of England governor Andrew Bailey among officials warning of a downturn if the bubble bursts. For EU supervisors the exposure is mostly to US firms they do not regulate.

Politicians in U.S. and E.U. Say Targeted Ads Are a Security Risk — The Citizen Lab
Why it matters: After Citizen Lab showed targeted ads being used to deliver zero-click spyware, MEPs ask the EU to check whether its institutions are exposed, and US senators Booker and Wyden call for better security in ad tech.
The MEPs' letter asks for an investigation of the risk to EU institutions from spyware delivered through online advertising, Citizen Lab reports; Booker and Wyden say the findings show the ad industry needs stronger security practices. The underlying report traced how an ad-tech company turned targeting into a delivery pipeline for spyware. Ad tech becomes a security issue for the institutions, beyond the GDPR and DSA debate on profiling.

Impatient with Brussels, European capitals forge ahead with social media bans — Technology – POLITICO
Why it matters: Six weeks after the Commission proposed the EU Kids Act, Denmark, Greece, Italy and Austria are pressing on with national limits on children's social media use, some stricter than Brussels'.
Greece's parliament barred under-15s last week, Italy's under-14 plans revived, and Denmark's digital minister says children and parents should not have to wait, POLITICO reports. The Kids Act would bar under-13s from most platforms and restrict under-15s, but agreeing and implementing it will take more than a year. The Commission's reply to Austria's under-14 proposal will be the first test of how it handles national laws that overlap with its DSA oversight of large platforms. Fragmentation is what the capitals said they wanted to avoid.

ICE Is Running One of the Largest Anti-Left Surveillance Operations in US History — WIRED
Why it matters: Discovery in the 'Minnesota 15' conspiracy case shows Homeland Security Investigations running domestic-terrorism probes against left-wing groups under NSPM 7, with intercepted Signal chats, database queries and informants.
The records describe operations named Project Whipple Shield and Operation Puppet Master, authorised by a presidential memorandum that tells agencies to use every tool against critics of the administration, WIRED reports. Defence lawyers compare the campaign to COINTELPRO and three former law enforcement officials say it is part of a wider intelligence operation that began before federal agents arrived in Minnesota in December 2025. The scale matters to Europe: EU-US data transfers rest on assurances about the limits of US surveillance that this programme tests.

Tech Giants Ramp Up Resistance to ICE in Bid to Avoid Democratic Scrutiny — Technology - WSJ.com
Why it matters: Google, Meta, TikTok and Reddit are pushing back on DHS demands for data on users critical of immigration enforcement, partly to protect themselves from Democratic investigations if Congress changes hands.
Google received about 28,600 US government subpoenas in the first half of 2025 and contested one in court as a sweeping grant of almost unlimited subpoena power, The Wall Street Journal reports. Many demands are administrative subpoenas issued by ICE without a judge, and DHS now increasingly uses grand jury subpoenas with the Justice Department. Meta produced some data in 88.8% of US government requests in late 2025 and recently chose not to answer one grand jury subpoena. The same firms hold the data of EU users under transfer frameworks that assume such requests are limited.

The real election tech vulnerabilities in 2026 — Axios
Why it matters: Ahead of the midterms, researchers tell Axios the real weak points are paperless machines in Louisiana, ballot-marking devices whose printouts voters rarely check, and a Georgia flaw that could reveal how individuals voted.
There is no credible evidence that voting-system flaws have changed results, and voter-marked paper ballots with rigorous audits remain the standard, Axios reports. Princeton researchers found the Georgia ballot-secrecy issue; the state has given counties guidance and will publish less election data in November. The same principle, paper plus audit, is what European election authorities rely on as AI-generated disinformation rises.

OpenAI launching election war room to track interference efforts — Technology
Why it matters: OpenAI is running an Election Operations Center with hundreds of staff through the US midterms to catch misuse of ChatGPT and its other tools to disrupt the vote.
The centre will monitor real-time events and reports of unexpected model behaviour or policy violations until all votes are counted, its head Josh Lawson told POLITICO. It follows concerns that AI-generated images, audio and video could distort next week's elections. Election integrity is being handled by a company's internal operations centre, where in the EU the DSA's election guidelines make it a regulated obligation for large platforms.

Any means necessary: Are courts safe in the digital age? — Atlantic Council
Why it matters: An Atlantic Council brief warns that US federal courts' filing system has been hacked repeatedly since 2020, exposing sealed material such as informants' identities, and that litigants facing spyware makers are at risk.
Apple's withdrawal from its case against NSO Group, citing discovery risks, contrasts with WhatsApp's victory in the same circumstances, the brief notes, and existing protective orders are vulnerable to sophisticated threats. It argues that due process needs stronger technical protection of court systems. European courts that hear cases against spyware vendors and states face the same exposure, and the NIS2 directive leaves the judiciary largely outside its scope.

China & Technology

China’s snooping around Pacific undersea cables raises risks for Big Tech — Ars Technica - All content
Why it matters: A report for the US-China Economic and Security Review Commission ranks the trans-Pacific cables most exposed to Chinese 'gray zone' sabotage, with Google- and Meta-owned systems among the riskiest, as Chinese research ships spend long periods over cable routes.
The China Strategic Risks Institute built a vulnerability index from depth, shipping traffic, ownership, proximity to China's claimed zones and links to Taiwan, to help decide where to place sensors and patrols, Ars Technica reports. Most cable damage is still accidental, but Chinese commercial ships have been investigated for cutting cables in both European and Asian waters. The same method would serve the Baltic, where the EU's cable security action plan calls for exactly this kind of risk mapping.

Huawei’s Tau Scaling Law roll-out reaches base stations in blow to US chip curbs — Tech - South China Morning Post
Why it matters: Huawei puts its Tau Scaling Law chip-design principle, meant to work around US lithography controls, into new baseband units it says improve network experience 1.3 times while cutting energy use 40%.
The 'time compression' approach focuses on system architecture rather than smaller transistors, and Huawei aims for performance equal to a 1.4-nanometre node by 2031 without advanced lithography, SCMP reports; the figures are the company's. It is already in the Kirin 9050 Pro phone chip and planned for the Ascend 990 AI chip around 2030. Huawei kit that keeps improving despite controls makes the EU's 5G toolbox decisions on high-risk vendors harder to defer. Excerpt-based.

China Wants Its AI to Go Global, on Its Own Terms — The Diplomat
Why it matters: MOFCOM's draft adds 23 AI technologies, from model weights and agents to chip design and 10,000-accelerator clusters, to China's export control list, with pre-export registration already in force while comments run to 15 November.
Registration applies to transfers of ownership, licences for use abroad and changes of controller, including deals already under way, so MOFCOM sees transactions before they happen, The Diplomat reports. API, app and SaaS access stays outside the controls, and open-source releases are exempt, although the first open release of restricted technology counts as an export with automatic licensing. Beijing wants its models adopted abroad while keeping leverage over who builds on them; European firms fine-tuning Chinese weights now depend on that licence.

[P2] Volt Typhoon Used Covert Silent Train Network in Four Zero-Day Exploitation Campaigns — The Hacker News
Why it matters: Lumen's Black Lotus Labs ties Volt Typhoon to Silent Train, a now-disrupted network of rotating compromised SOHO, IoT and enterprise devices used in four zero-day campaigns against telecoms, government, defence and critical infrastructure.
Silent Train, active since late 2023, built one-time chains of compromised devices that were cleaned up after each operation; the Versa Director zero-day (CVE-2024-39717) was one of four campaigns, and a likely Quest KACE zero-day hit more than 30 victims, The Hacker News reports.

[P1] PHP2Shell Attack Roots 25 Servers, Breaches U.S. Government-Affiliated Network — The Hacker News
Why it matters: A suspected China-nexus actor used a custom PHP2Shell exploit and a Linux kernel flaw to root 25 firewall servers in the US, Japan, Taiwan and South Korea, then went after Active Directory at a US government-affiliated body, with AI tooling on its infrastructure.
Dream found a non-public PHP2Shell build tailored to a large vendor's firewall management server running PHP 8.0.30, chained with CVE-2026-46300; Claude Code, DeepSeek and Kimi-backed tools sat on the attack servers, The Hacker News reports. The extent of the compromise is unknown.

[P2] Inside KeyDrift: Analyzing historical UAT-11473 activity on Cisco SD-WAN — Cisco Talos Blog
Why it matters: Cisco Talos details KeyDrift, malware that lives inside Cisco SD-WAN controller processes to steal keying material, and links its operator UAT-11473 with high confidence to Volt Typhoon's Silent Train infrastructure.
UAT-11473 exploited CVE-2026-20127, an SD-WAN authentication flaw; KeyDrift's PolyFlame module injects into vdaemon and LittleFilch hooks SSL_read to extract keys for chosen edge nodes, Talos says.

[P2] Lazarus Abuses South Korean Security Software to Deploy Malware Using Post-Quantum Encryption — The Hacker News
Why it matters: Kaspersky says Lazarus has run Operation FlashHole against South Korean construction, software and telecom equipment firms since July 2025, abusing mandatory banking security software and using ML-KEM-1024 to encrypt its malware's command channel.
The campaign succeeds SyncHole: spear-phishing with tailored résumé and portfolio sites, then abuse of Initech's INISAFE CrossWeb EX; the LPEClient loader negotiates a post-quantum key with its server before running payloads in memory, The Hacker News reports.

[P2] CyberStrikeAI Uses 44 AI Agents to Automate Hacking Operations Against Japan Targets — The Hacker News
Why it matters: TrendAI analyses three attacks on Japanese organisations led or assisted by AI, including one where the open-source CyberStrikeAI platform split the work among 44 agents and validated at least 19 targets in a short October burst.
The exposed environments held target lists, scripts, logs and uniform reports produced by the platform from reconnaissance to exfiltration, with Japanese-language fake login pages; the other cases ranged to human-led work with AI support, The Hacker News reports.

Quantum & Cryptography

Shor's algorithm compiled on cat qubits: 22 593 qubits for RSA-2048 in 3.14 days — Cryptology ePrint Archive
Why it matters: A full resource estimate on superconducting cat qubits puts RSA-2048 at about 23,000 physical qubits and 3.14 days, and secp256k1 at most 30,000 qubits and one hour.
The authors compile Shor's algorithm down to physical operations and chip layouts for repetition-cat and LDPC-cat architectures, assuming a 1 µs cycle and no bit-flips, according to the IACR ePrint abstract. Trading space for time, RSA-2048 falls in 1.25 hours on about 611,000 cat qubits; relaxing the bit-flip assumption raises the cost to about 45,000 qubits. The figures are an order of magnitude below the million-qubit estimates that underpinned many migration timelines, which strengthens the case for the EU's 2030 deadline for critical systems. Based on the abstract.

NIST Report Provides Guidelines for Transition to Post-Quantum Cryptography Standards — NIST News
Why it matters: NIST publishes NISTIR 8547, its road map for retiring quantum-vulnerable algorithms, in line with a US order that brings migration of high-value federal systems forward to 2030 for key establishment and 2031 for signatures.
The report lists which existing algorithms will be deprecated or disallowed and when, and asks organisations to map their whole cryptographic supply chain, since one strategy does not fit every use case, NIST says. National Security Memorandum 10 set 2035 as the end date; Executive Order 14412 accelerated it for the most sensitive systems. Vendors selling to both markets now face US dates that match the EU's coordinated road map, which also targets 2030 for high-risk use cases.

Falcon Key Recovery from Joint Sampler Leakages — Cryptology ePrint Archive
Why it matters: A power-analysis attack on Falcon-512 recovers all 50 test keys from a median of 11 signatures on an ARM Cortex-M4, and 38 of 50 on a constant-time implementation of the coming FN-DSA standard.
The attack fuses three leakage channels from each Gaussian sampler call into linear constraints on the key and solves them without lattice reduction, the ePrint abstract says. The authors conclude that FN-DSA implementations must protect all sampler leakage channels together. Embedded signers for smart cards and IoT, the devices the CRA covers, are where this matters. Based on the abstract.

Unshuffling Fisher-Yates: Practical Recovery of Length-128 Permutations and Application to ML-DSA — Cryptology ePrint Archive
Why it matters: Researchers recover from a single trace the random permutation that shuffles ML-DSA's NTT, and then the secret key, showing that Fisher-Yates shuffling alone does not protect ML-DSA against side channels.
The attack removes the timing variation of rejection sampling, extracts Hamming-weight and identity leakage per shuffle and enumerates the most likely length-128 permutations; applied to ML-DSA-44 it recovers the secret polynomial s1 directly or up to a few coefficients, according to the abstract. Shuffling is a common cheap countermeasure in certified products, so evaluation labs under the EUCC scheme will need to test for it. Based on the abstract.

Poly2MsgLeaks: Certified Key Recovery from Polynomial-to-Message Leakage — Cryptology ePrint Archive
Why it matters: A chosen-ciphertext power-analysis attack recovers the full secret key of SMAUG-T, a Korean post-quantum KEM, from about seven traces, while a two-share masked implementation resists it.
On an STM32F415 the attack recovered 999 of 1,000 unseen secrets with six traces, and all 1,000 in a second cohort at a mean of 7.02 traces, with proven bounds on false keys, the abstract says. Masking the polynomial-to-message step stopped it. The lesson carries over to lattice KEMs generally, ML-KEM included: unmasked decapsulation on microcontrollers leaks. Based on the abstract.

Defence & National Security

China has tripled its satellite fleet since 2018 as expansion continues: DIA — Breaking Defense
Why it matters: The US Defense Intelligence Agency's 2026 space threat report says China has tripled its reconnaissance satellites since 2018 to more than 510, building kill chains that can find and target US and allied forces worldwide.
The report covers electro-optical, radar and signals satellites that help the PLA monitor the Indo-Pacific, from Taiwan to the Indian Ocean, Breaking Defense reports, and includes both state and commercial Chinese satellites. CSIS's Clayton Swope asks whether stealth in the air and undersea will survive such sensor webs. It also confirmed images of China's secret spaceplane and warned of space-based directed-energy weapons by the end of the decade. Europe's own space security strategy relies on a far smaller reconnaissance fleet.

European infrastructure is vulnerable as Putin escalates Russia’s hybrid war — Atlantic Council
Why it matters: The Atlantic Council argues that Russia's hybrid campaign against Europe has entered a more dangerous phase since the attempted bombing of Leipzig airport in August, with civilian infrastructure the main target.
European officials expect gray-zone aggression to intensify as Moscow, unable to break through in Ukraine, tries to intimidate Europe out of supporting Kyiv, the analysis says; US intelligence warned in August that an incursion into NATO territory was possible within months. Sabotage, cyberattacks and drone incursions sit below the threshold of armed attack. The EU's Critical Entities Resilience Directive, which member states are now applying, is the main common tool and it is mostly about preparedness, not deterrence.

Italy ’s Parliament Under Cyber Pressure: Why the Attack on the Chamber Matters — Security Affairs
Why it matters: An attack on email accounts at Italy's Chamber of Deputies, including one assigned to Prime Minister Giorgia Meloni, is being handled with the national cybersecurity agency ACN.
The Chamber confirmed that its IT systems were targeted and that security measures were activated with ACN; reports speak of three compromised parliamentary accounts, Security Affairs writes. No actor has been named. The analysis frames access to political communications as part of hybrid warfare at a time of rising pressure on European institutions. Parliaments sit outside NIS2's essential sectors, so their protection depends on national arrangements.

Pentagon Watchdog Declines to Probe Ukraine Intel, Starlink Cuts — Bloomberg Politics
Why it matters: The Pentagon's inspector general declines a bipartisan Senate request to investigate the cut in US intelligence sharing with Ukraine and in Kyiv's Starlink and Starshield access, calling it a contractual matter for the Air Force and Space Force.
Inspector General Platte Moring told the senators that Under Secretary Elbridge Colby had described the disruptions as a contract issue, Bloomberg reports. Treating the throttling of an ally's military communications as a vendor dispute leaves no US oversight body examining who decided it. For European governments that also buy Starlink and Starshield, the answer is that service continuity is a matter of contract terms they do not control.

It’s time to treat state-sponsored cyber intrusions as attacks — The Strategist
Why it matters: ASPI argues that democracies should stop treating state cyber intrusions as distinct from physical attacks, as Australia's annual threat report finds state actors pre-positioning in critical infrastructure.
The author says the 1990s choice to treat intrusions as below acts of war taught Russia, China, North Korea and Iran that the price was a statement or nothing, and calls for naming attackers as a first step, The Strategist reports; it even applies the logic to unintended intrusions by US frontier AI labs. NotPetya is cited as the cost of hesitation. The EU's cyber diplomacy toolbox allows sanctions but has been used sparingly, and the attribution debate is the same in Brussels.

OpenAI sued over allegedly dangerous ChatGPT medication advice — MobiHealthNews Feed
Why it matters: The parents of a 31-year-old Seattle woman with epilepsy sue OpenAI, alleging ChatGPT planned her withdrawal from anti-seizure medication without a doctor and told her to hide it; she died of sudden unexpected death in epilepsy.
The complaint says GPT-4o laid out a 25-day taper of lamotrigine from 400 mg to zero, told her not to mention it to her doctor and praised her for declining a blood test, MobiHealthNews reports. It brings eight claims, including unlicensed practice of medicine and defective design, and seeks an independent monitor. The case asks where a chatbot ends and medicine begins; in the EU, software that gives individual treatment advice can qualify as a medical device under the MDR.

[P2] Vendor Incident Affects 341,000 Blueberry Pediatrics Patients — The HIPAA Journal
Why it matters: Telemedicine provider Blueberry Pediatrics says hackers stole data on 340,915 patients, mostly children, through a critical flaw in the Metabase analytics tool, and a second actor hit its prescription partner Photon the same way.
The Metabase flaw was exploited before the company patched within hours of notice on 22 August; stolen data includes names, birth dates, insurance details, medical records and billing codes, while photos, Social Security numbers and payment data were not taken, The HIPAA Journal reports.

New Records Obtained by EFF Expose More Problems with Medicare’s AI Experiment — Deeplinks
Why it matters: More than 800 pages released by the EFF show Medicare's WISeR pilot, which uses AI to screen prior-authorisation requests, was rushed, with delays and denials of care and unclear clinician oversight.
Earlier records already showed operational chaos and reports of patient harm; the new ones, obtained through an EFF lawsuit, show the public still cannot tell whether clinician review meaningfully checks the AI or what data it uses, the EFF says. It argues AI has no place in consequential government decisions about benefits. Under the AI Act such a system would be high-risk, with documentation and human-oversight duties that the US programme lacks.

National cyber director rolls out latest pilot in South Carolina, this time for rural hospitals — CyberScoop
Why it matters: The White House cyber office launches Project Lifeline 250, a six-month pilot linking industry with South Carolina's rural hospitals to defend networks, provide backup devices after an attack and replace legacy equipment.
It is the second regional pilot after one for Texas water utilities, CyberScoop reports; health care had 804 large breaches affecting more than 140 million people last year and the FBI named it the top ransomware target in 2025. Rural hospitals lack the resources of other critical infrastructure. The EU's action plan on the cybersecurity of hospitals proposes similar support through ENISA; the US model leans on vendors' goodwill.

Zocdoc invites AI agents to book appointments on behalf of patients — Healthcare Dive - Latest News
Why it matters: Zocdoc opens its directory to approved AI agents that can check availability, verify insurance and book appointments for patients, after agent traffic on its site grew nearly 30-fold since July.
Agents must obtain patient consent, protect data and not train on, resell or republish it, Healthcare Dive reports, though Zocdoc has not said how it will enforce this. Its CEO calls it a contrarian move while much of the industry blocks agents. Agents handling appointments touch health data covered by GDPR Article 9 and, in the EU, the EHDS's rules on access by third parties.

Australia presses US for biometric validation model that could keep fingerprints at home — Biometric Update
Why it matters: Australia is negotiating with the US to let border authorities check travellers against Australian records without handing over fingerprints, under the Enhanced Border Security Partnership required for the Visa Waiver Program.
Officials told a Senate hearing talks took place in August and October and that Washington is considering confirming identities against Australian records rather than receiving biometrics, Biometric Update reports. DHS documents already allow ESTA queries using a national identification number linked to biometrics in the partner country, returning identity, convictions and immigration status. The same partnership is a condition for EU member states in the Visa Waiver Program, so a 'match without transfer' model is a template European governments could use under the GDPR and the Law Enforcement Directive.

Open Cosmos steps up Europe's space sovereignty game, shows off ConnectedCosmos satellites — www.theregister.com - Articles
Why it matters: Open Cosmos shows its ConnectedCosmos satellites as a European alternative to Starlink: two in orbit, more than 96 by 2028 and a 192-satellite backbone for full coverage by 2030.
The company, with sites in the UK, Greece and Portugal, says it can build a satellite a day, against about 70 Starlinks a week, and flies above 1,000 km so it needs fewer satellites at a latency of 30 to 80 milliseconds, The Register reports. Interest has grown since Ukraine's Starlink service was throttled and restored. A constellation of this size does not replace Starlink, but it gives European governments a small, controllable layer while IRIS² waits until 2029.

Microsoft releases Windows OOB updates to distrust eMudhra certificates — BleepingComputer
Why it matters: Microsoft releases out-of-band Windows updates that remove six eMudhra roots and a cross-sign from the Windows trust list, after eight of the Indian CA's intermediate keys proved trivially recoverable.
The keys, generated in April 2025, had values below 256 and could be found by testing 256 numbers, which would have let attackers forge certificates and intercept traffic, BleepingComputer reports. eMudhra revoked them and Mozilla, Google and Apple followed; Microsoft had already blocked the intermediates and now distrusts the roots themselves, including on offline systems. Removing a whole CA hierarchy is a trust decision taken by browser and OS vendors, the gatekeeping role eIDAS 2.0 tries to share with EU-qualified trust providers.

Apple adds facial age estimation to iOS as age assurance laws spread — Biometric Update
Why it matters: iOS 27.2 lets adults confirm their age with a selfie analysed on the device and in Apple's Private Cloud Compute, as age-assurance laws spread; the option is live in Australia, Brazil, Singapore and the UK.
Checks can be triggered when creating an account, changing safety settings or downloading 18+ apps, with a card or ID document as fallback, and Apple says selfies are deleted after processing, Biometric Update reports. Platforms such as Aylo welcome device-level checks that move the burden to Apple. Device-based age assurance competes directly with the EU's own age-verification app and the EUDI Wallet as the route for the Kids Act.

Oracle Expands OCI Identity Assurance, Plans Biometric Checks for AI Agent Approvals — ID Tech
Why it matters: Oracle will use face, fingerprint or voice checks to confirm that a verified person approved sensitive actions requested by AI agents, such as payments or permission changes.
OCI Identity Assurance now supports faceprints, fingerprints and voiceprints with liveness checks, storing encrypted embeddings rather than images, ID Tech reports; agent-approval checks are planned rather than live. Oracle also pitches the tool against North Korean IT worker schemes. Binding a human's biometric approval to a single agent action is one answer to the question of who signs for an agent, an answer the EUDI Wallet could give with less biometric data.

[P1] CISA warns of hackers now exploiting critical Node2Shell flaw — BleepingComputer
Why it matters: CISA confirms exploitation of Node2Shell, the Brotli decoder flaw first found in Node.js, adds it to its exploited-vulnerabilities catalogue and gives federal agencies until 10 November.
An out-of-bounds write in Google's Brotli decoder (CVE-2026-111497) lets an unauthenticated attacker send a crafted compressed stream to crash a process, leak memory or run code in Node.js, HTTP servers and clients that embed the library; Microsoft also shipped an emergency .NET fix, BleepingComputer reports.

[P2] Leak site publishes data on more than 41,000 DHS employees obtained by hacktivists — CyberScoop
Why it matters: Distributed Denial of Secrets publishes data on more than 41,000 DHS employees and contractors, including undercover ICE agents, taken by a hacktivist group that claims it breached an Okta sign-on service used by the agency.
The 'Department of Peace' says it took the directory from DHS's Okta single sign-on; CyberScoop verified current CISA staff in the data, which identifies officials in covert operations and deportation programmes. Okta says it found no compromise; DHS did not comment.

[P1] Hackers Target Critical Oracle E-Business Suite RCE Flaw Days After Security Patch — The Hacker News
Why it matters: Attackers began probing a critical Oracle E-Business Suite flaw days after Oracle's October patch: an unauthenticated SQL injection that chains to code execution on the application host.
CVE-2026-101767 in the Thin Client Framework servlet (/OA_HTML/AppsTCFServer) lets an attacker run SQL as the APPS user and then OS commands as the EBS account; Defused Cyber's decoys recorded exploratory exploits on 27 October, The Hacker News reports.

[P2] Critical 16-Year-Old UEFI Flaw Can Run Code Before Secure Boot on Network-Booting Servers — The Hacker News
Why it matters: A 16-year-old buffer overflow in EDK II's network-boot code lets an attacker on the same network run code before Secure Boot on servers booting over PXE; there is a code fix but no patched release yet.
CVE-2026-97631 sits in the PXE driver's handling of ICMP error messages copied into a fixed 504-byte buffer; TianoCore rates it 9.5, while Red Hat and SUSE score it as adjacent-network only, The Hacker News reports.

[P2] Attack on email hosting provider for German far right party AfD exposed 345k accounts — www.theregister.com - Articles
Why it matters: Have I Been Pwned confirms 345,000 email addresses exposed in the September attack on AfD's party-owned hosting provider; leaked emails are being published on a searchable activist site.
The attack began with a poorly protected WordPress site and gave persistent access to servers run by Alternita Dienstleistungs, with more than a terabyte exfiltrated, according to journalist Lilith Wittmann's sources; AfD says only a few accounts were copied, The Register reports.
