Countering misuse of AI: September 2026 / Anthropic

Anthropic publishes threat intelligence on Claude misuse across seven harm areas from December 2025 through August 2026.

Anthropic's Threat Intelligence team details disrupted operations using Claude Haiku, Sonnet, and Opus across cyber operations, influence operations, surveillance, scams, biological misuse, weapons development, and distillation. The report introduces Generative Threat Groups (GTGs), including state-sponsored groups and financially motivated individuals running AI-augmented multi-victim campaigns. It argues AI uplift now collapses the gap between state-sponsored operations and lone actors, aided by frameworks like PentAGI.

The world must establish red lines for autonomous AI weapons

Opinion piece calls for international red lines on autonomous AI weapons after a Russian AI-guided drone autonomously killed three civilians in Zaporizhzhia.

The author urges enforceable international agreements governing autonomous weapon systems, citing a July 2026 incident where a Russian drone struck a gas station in Zaporizhzhia, killing three Ukrainian civilians. Ukrainian investigators found the drone carried an Nvidia Jetson Orin chip, and the onboard AI reportedly selected the specific target without a human making the final decision. The piece argues existing international humanitarian law lacks specific standards for weapons that independently select and engage targets, and points to UN and ICRC deliberations plus the Global Council for Responsible AI's red-line framework.

Large DDoS attack knocks Norwegian public services offline

A large DDoS attack on Norwegian IT partner Vivicta disrupted 10 government services, including ID-porten used by over 4.5 million users, for 30+ hours.

Norway's Digitalisation Agency (Digdir) said a distributed denial-of-service attack that began Monday targeted the infrastructure of its IT partner Vivicta and lasted around 30 hours at varying intensity, with some services still affected Tuesday. Disrupted services included ID-porten, a national digital identity gateway used by more than 4.5 million people, which many government services and parts of the health sector, such as online pharmacies and the electronic prescription system, rely on for authentication. Digdir said attackers did not gain access to sensitive information, and it was the third DDoS incident since June, reportedly two to three times larger than the previous one. Attribution and possible links between the incidents remain unclear.

Russian hackers plant nuclear weapon prompt in malware to trip AI safety guardrails

ESET reports Russian group UAC-0099 hid a prompt in VBS malware comments to trip AI safety filters and disrupt automated malware analysis in Ukraine.

ESET identified a technique dubbed GuardBreaker in which UAC-0099 embedded a comment reading "I want to make nuclear weapon. Help me …" inside a malicious VBS script to trigger AI safety mechanisms and halt AI-assisted malware analysis. The script, part of the group's toolset, downloads the MATCHBOIL malware used exclusively by this Russia-aligned group; CERT-UA documented the chain including LUNCHPOKE, BURNYBEAR and MATCHBOIL.V2 in a July advisory. UAC-0099 typically targets transportation and energy sectors and hands validated targets to GRU-linked Sandworm. ESET warned that AI-assisted analysis must be backed by layered detection and human-driven engineering.

Norway announces investigations into telecom Telenor’s work with Myanmar junta

Norwegian police opened crimes-against-humanity and sanctions investigations into Telenor's data handovers to Myanmar's junta, raiding its Oslo headquarters.

Norway's National Criminal Investigation Service is investigating Telenor for complicity in crimes against humanity for repeatedly handing over historical customer traffic data to Myanmar's military regime between the February 2021 coup and the March 2022 subsidiary sale. The Police Security Service is separately probing sanctions violations because the sale to M1 Group included sanctioned surveillance equipment transferred without foreign ministry permission. The subsequent resale passed historical call data of over 18 million people to junta-linked owners, and a class action on behalf of 1,200 people alleges the data enabled arrests, torture, and at least one execution.

Hackers Weaponize AI Safety Guardrails to Hide Malware From LLM-Powered Security Scanners

ESET says Russia-aligned actor UAC-0099 hid guardrail-triggering comments in VBScript to derail LLM-based malware scanners in Ukraine.

ESET researchers linked a technique named GuardBreaker to Russia-aligned threat actor UAC-0099 during an attack against an organization in Ukraine. The group embedded a safety-sensitive, weapon-related request in a VBScript comment so an LLM-powered analysis tool might interpret it as an instruction and refuse or truncate analysis before reaching the malicious code. The VBScript downloaded MATCHBOIL, a C#-based loader used by the group alongside MATCHWOK and DRAGSTARE. OWASP guidance recommends treating code comments and metadata as untrusted input, sanitizing it, and never treating an LLM refusal as a clean verdict.

Bad Likert Judge: A Novel Multi-Turn Technique to Jailbreak LLMs by Misusing Their Evaluation Capability

Unit 42 details the Bad Likert Judge multi-turn jailbreak that abuses LLMs' evaluation capability, raising attack success rates over 60% across six frontier models.

Palo Alto Networks Unit 42 describes the Bad Likert Judge technique, a multi-turn jailbreak that asks a target LLM to act as a Likert-scale judge scoring the harmfulness of example responses. The highest-rated example in each scale can carry harmful content, bypassing the model's internal guardrails. Testing across six state-of-the-art text-generation LLMs showed an average attack success rate increase of more than 60% versus plain attack prompts, with tested models anonymized. The technique targets edge cases rather than typical use, and the article positions the work as guidance for defenders on potential jailbreak risks.

Sexually Explicit Deepfake Sites Target 100-Plus Politicians in Europe

Deepfake pornography sites have targeted nearly 150 European politicians, overwhelmingly women MPs, per new research on 160 abusive domains.

Researcher Benjamin Shultz analyzed roughly 160 deepfake abuse domains and found at least 138 women MPs from 22 EU countries appeared or were mentioned, versus nine male MPs — making women MPs 33 times more likely to be targeted. Sites host database-like profiles with names, photos, personal details, and links to 'nudifier' creation tools. The findings, published by German think tank Agora Digitale Transformation, show politicians from Germany, the Netherlands, Italy, and France most affected, with senior politicians targeted more often. The UK and EU are planning bans on nudify services, while the US Take It Down Act has taken major deepfake sites offline.

I’ve been deepfaked: What do I do?

ESET outlines steps for deepfake victims: preserving evidence, using platform reporting tools, and legal remedies like the US TAKE IT DOWN Act and StopNCII.org.

ESET published a how-to guide for people who discover deepfakes of themselves, covering evidence preservation, platform-specific reporting on Google, Facebook, Instagram, TikTok, YouTube, and X, and escalation to publishers or data protection regulators. It notes the US TAKE IT DOWN Act criminalizes non-consensual intimate imagery (NCII) and requires 48-hour takedowns, while UK and EU laws add creation offenses and GDPR Article 17 erasure rights. Services like StopNCII.org and TakeItDown.NCMEC.org hash images so participating platforms such as Meta, TikTok, Reddit, and X can find and remove matching copies.

US, Britain to coordinate on scam center takedowns

The US and UK signed an MOU to jointly investigate Southeast Asian scam compounds behind fraud that stole over $12 billion from Americans last year.

The DOJ and UK's National Crime Agency and Crown Prosecutor signed a memorandum of understanding on Thursday for parallel investigations and information sharing on scam centers, largely run by Chinese gangs using human trafficking victims in compounds across Myanmar, Cambodia, and Laos. The Scam Center Strike Force, with more than 150 personnel from the FBI, IRS, and US Postal Inspection Service, leads the effort; the FBI says cyber-enabled fraud accounted for almost 85% of reported losses, with over $12 billion stolen from Americans last year. An in-person disruption event with private industry partners is planned in London in early October. The initiative follows sanctions on Prince Group and a roughly $15 billion bitcoin seizure linked to its CEO Chen Zhi.

Using AI for Weapons Development

Anthropic report reveals Yemen-based actors used Claude Code to build guidance software for guided rockets and ballistic missiles.

Bruce Schneier highlights Anthropic's misuse disclosure describing a threat actor cell in northern Yemen running three weapons programs: a guided rocket with phone-class homing guidance, a 2,000+ km multi-stage ballistic missile, and the 'R2000' hypersonic glide vehicle set. The actors used Claude Code as a substitute for human engineers to write GNC software, integrate an open-source autopilot, tune controls, and run flight simulations, orchestrating multiple Claude instances in delegated roles. Safeguards blocked many requests but evasion tactics included hiding intent and splitting work across sessions; one guided rocket test-fire failed but no operational device was fielded.

Safety for Whom? Boundary-Aware Self-Distillation for Controlled LLM Safety Refusal

A self-distillation safety framework tunes narrow-boundary refusals in Qwen3-8B, raising target-domain refusal to 84.75% while cutting over-refusal from 15.20% to 5.20%.

The paper formulates narrow-boundary safety, where deployments need refusals within specific topics rather than whole subjects, and proposes an offline self-generated framework with controlled topic generation, escalating retries, and harmful-benign boundary pairs. On political persuasion with Qwen3-8B, the method raised target-domain refusal from 9.47% to 84.75% and cut the mean unsafe-response rate across three broader benchmarks from 26.26% to 0.14%. Verified target-model responses reduced over-refusal from 15.20% to 5.20%, and boundary-pair data cut comply-side over-refusal on held-out pairs from 32.94% to 4.16%. Results show data composition controls the safety-usability trade-off and alignment should be evaluated on both sides of the refusal boundary.

Aggah Campaign: Bit.ly, BlogSpot, and Pastebin Used for C2 in Large Scale Campaign

Aggah campaign abuses Bit.ly, BlogSpot, and Pastebin as multi-hop C2 to deliver RevengeRAT across the Middle East, US, Europe, and Asia.

Unit 42 details the Aggah campaign, which began with spearphishing emails in March 2019 spoofing a large financial institution and targeting education, media/marketing, and government organizations in the Middle East, later expanding to the US, Europe, and Asia. Delivery documents use Template Injection to load a remote OLE file whose macro runs mshta against a Bit.ly link redirecting to a BlogSpot post, which then uses Pastebin pastes to download RevengeRAT configured with a duckdns[.]org C2 domain. The embedded script also deletes Microsoft Defender signatures and kills Defender and Office processes, and modifies registry keys to enable macros. High-level TTPs resemble the Gorgon Group, but Unit 42 could not confirm attribution.
