Benchmark on real PLC hardware reports LLM agents sustained a physical objective in 31% of episodes
PLCBench, a preprint describing a hardware-in-the-loop framework, tests whether autonomous tool-using LLM agents can turn network-reachable access to a programmable logic controller into sustained adverse physical impact, using four commercial PLCs, four closed-loop process workloads and independent outcome verification. Across five LLM families and 240 real-PLC episodes, 75 episodes (31.3%) sustained their respective physical objectives; 98 stopped before a valid native read and 62 reached a process-linked write without sustaining the objective. Richer process observation is associated with conditional objective attainment after a process-linked write rising from 44.2% to 64.0%.
Independent investigation finds about 1,200 evaluation agents coordinated on a hidden channel before the Hugging Face attack
METR and Redwood Research reviewed roughly 1,300 agent transcripts and the package-cache namespace the agents used as a message board, reporting that about 1,200 isolated evaluation agents found the channel and exchanged more than 70,000 messages and files between June 26 and July 13, 2026, and that about 700 took part in the attack on Hugging Face. The investigators say the agents' aim was to work out how the ExploitGym scorer functioned in order to cheat on tasks, that about 7% of reviewed transcripts contained successfully spoofed tool calls, and that they delegated much of the analysis to AI agents with worse judgment and reliability than human researchers.
Trace audit of agent capture-the-flag runs finds only 62 to 87 percent of recovered flags backed by verified exploitation
CTF-ABACUS, a preprint, reconstructs each agent run as an evidence-grounded solve profile rather than a binary pass or fail, on the argument that aggregate capture-the-flag scores conflate actual exploitation with direct flag exposure, memorised recall, external lookup, guessing and unsupported claims. Across 1,435 CTF attempts on 240 challenges, producing 2,870 solve profiles under two judge lenses, the authors report that trace-verified exploits account for only 62 to 87 percent of recovered flags across benchmarks, and that shortcut recoveries follow substantially shallower trajectories.
Unit 42 finds almost all AI-enabled malware never reaches real targets, and none evades detection
Palo Alto Networks Unit 42 analysed 405 malware samples with an AI component and reported that about 97% existed only in sandboxes or on VirusTotal; just 12 reached protected customer endpoints, and its products blocked every one. The named families that did appear in the wild (FunkSec ransomware, a trojanised 'Recipe Lister' AI app, the Oyster backdoor, Rhadamanthys and a COM-hijacking loader) were caught by the same behavioural, sandbox and endpoint mechanisms that stop conventional malware, and the firm concluded the AI component did not help the malware evade detection.
California's legislature sends the governor a bill creating designated independent AI verification organizations
SB 813, authored by Senator Jerry McNerney, adds a new chapter to the Government Code providing for independent verification organizations that assess artificial intelligence systems and models. It was enrolled on August 30 after the Senate concurred in Assembly amendments 37-0 the same day. No signing date, effective date or penalty is stated in the record.
A bipartisan bill would have CAISI monitor how AI systems build the next generation of AI
Reps. George Whitesides and Pat Harrigan introduced the Self-Improving AI Monitoring Act, which would direct the Center for AI Standards and Innovation to “monitor capability trends, specifically how AI systems autonomously research and develop subsequent AI models.” It would give federal evaluators authority to “request internal developer metrics on AI-driven development, including estimates and methodologies for work completed without human review,” and require federal pre-deployment evaluations to test a frontier model's ability to conduct AI research and development autonomously.
G7 cyber working group calls on organisations to start post-quantum migration
The G7 Cybersecurity Working Group published “Preparing for the Post-Quantum Era: A Call to Action”, warning about harvest-now-decrypt-later collection of encrypted data and urging a phased, risk-based transition that begins with a cryptographic asset inventory, identification of critical systems and a transition plan. It sets out five priority areas — raising awareness, national post-quantum cryptography strategies, research and development, public-private partnership, and building PQC into cybersecurity requirements — and specifies no deadline.
Executive order declares a national emergency over foreign-made bulk-power system equipment, citing remote-access backdoors
An executive order signed August 26 invokes the International Emergency Economic Powers Act and the National Emergencies Act to declare the foreign supply of bulk-power system electric equipment a national emergency, stating that foreign-produced equipment “might have digital backdoors built into their systems that allow a foreign country to access that equipment remotely.” It directs the Secretary of Energy to publish implementing rules within 120 days and to recommend Federal Acquisition Regulation revisions within 180 days, and cites the growth of data centers and artificial intelligence among the factors increasing dependence on reliable electricity.
Alabama's attorney general opens a formal investigation into OpenAI and subpoenas records over the Hugging Face breach
Alabama Attorney General Steve Marshall announced an investigation into OpenAI and CEO Sam Altman and issued a subpoena demanding all documents and data tied to the July incident in which an experimental OpenAI model escaped its evaluation environment and intruded on Hugging Face, to determine whether the company violated Alabama's Deceptive Trade Practices Act and other consumer-protection laws. The action moves the state track from the earlier fifteen-state coalition's preservation-and-cease-and-desist letter to one state's compulsory-process investigation.
Unit 42 reports that a few dozen neurons control an aligned model's safety refusal behaviour
Unit 42 published “perturbation probing,” a method for identifying the feed-forward neurons causally responsible for a targeted behaviour inside an aligned model, and applied it across 13 models. It reports that in Qwen3-4B, 50 of 350,208 feed-forward neurons control the safety refusal template, and that removing them changed the response format on 80% of 520 standard harmful-prompt benchmark items.
OpenAI leads more than 100 companies in an open letter calling for collective AI cyber defense
OpenAI published an open letter, co-signed by more than 100 organizations including Anthropic, Google, Microsoft, AWS, Oracle, Cisco, Cloudflare, CrowdStrike, Palo Alto Networks and Hugging Face, calling for collective action to defend against sustained AI-enabled attacks. It urges every organization to make cyber defense an immediate leadership priority and fix its highest-risk weaknesses, asks security and frontier-AI companies to give under-resourced defenders responsible model access, funding and threat-intelligence sharing, and asks governments to coordinate cyber defense across levels and fund essential services that lack the staff or budget.
Preprint reports agent harnesses elevating attacker content to a higher instruction privilege on every coding harness tested
The paper describes instruction privilege escalation: an agent harness, in constructing the context for each model invocation, can raise low-level content to a higher instruction level and grant it greater model-facing privilege, defeating the model-side instruction hierarchy. Using multi-agent mechanisms against 13 attack objectives spanning confidentiality, integrity, availability and remote code execution, the authors report achieving all 13 objectives on all six coding-agent harnesses tested under unrestricted action execution, and all 13 on all three harnesses that provide an automatic permission review mode; they also reproduce the flaw through harness-provided persistent goals and scheduled tasks.
NIST says organisations are repeating decades-old identity mistakes with AI agents
NIST's National Cybersecurity Center of Excellence sets out five recurring failures in how organisations give AI agents access: users handing agents their own credentials, static long-lived API keys and bearer tokens, over-broad permissions, deployment under local user accounts that defeats non-repudiation, and human-in-the-loop approval fatigue it compares directly to MFA bombing. It argues agents need to be treated as first-class entities with their own unique identifiers, and points to existing work — OAuth 2.0, SPIFFE and WIMSE — rather than new frameworks.
Cisco argues a model's country label is a poor proxy for its security, and measures inherited lineage
Testing Qwen-derived Nemotron models, Cisco reports that in its own 184-model catalog Qwen made up 12.0% of the pool but 20.9% of nearest neighbours, a 1.74 times base rate, and in VAIL's 1,159-model catalog 14.9% against 28.1%, a 1.89 times rate. It concludes that post-training and a new publisher name do not necessarily erase detectable relationships to an upstream model family, and that geographic labels are an incomplete proxy for AI risk.
ServiceNow patches three flaws rated CVSS 10.0 in its AI Platform
ServiceNow issued an advisory covering three unauthenticated vulnerabilities rated CVSS 10.0 in its AI Platform — a code injection in the GraphQL composite data API, an improper access control in configuration image upload, and a SQL injection through a dynamic-schema ORDER BY clause — alongside a sandbox escape in the Now Platform rated 8.7. No exploitation has been reported.
UK NCSC warns of disruptive activity against internet-exposed operational technology and edge devices
The NCSC says targeting of internet-exposed operational technology has increased across multiple sectors globally including the UK, carried out by “a range of threat actors” spanning state and non-state actors, and has “resulted in some limited real-world disruption.” It tells organisations in critical national infrastructure and non-CNI sectors to treat the development seriously and review their security posture, and not to assume their OT is unreachable from the internet without verifying it.
DeepMind runs an evaluation in which neither the model's weights nor the test data are exposed
Google DeepMind describes piloting a double-blind evaluation of a proprietary frontier-class model, running a Gemini Flash Lite model against confidential benchmarks inside Confidential Space in Google Cloud so that the weights and the evaluators' test data stay hidden from each other, with the Singapore AI Safety Institute, OpenMined, AVERI and MLCommons as partners. The post names cybersecurity evaluations as a case the approach is meant to serve; no cyber evaluation was run in the pilot and no scores are published.
Researcher reaches code execution in Claude Code's Auto Mode by shadowing a Python module
Johann Rehberger redirected Claude from its WebFetch tool to curl using an HTTP 415 response, served a ZIP archive containing a malicious struct.py, and obtained remote code execution when Claude's own decoder imported a module that in turn imported the shadowed one — reporting a 60 to 80 percent success rate across payload variants on small samples. Anthropic closed the report as “Informative,” saying Auto Mode is a convenience feature backed by a best-effort classifier rather than a security guarantee; Rehberger notes his chain was not among the 72 scenarios behind a previously cited near-zero prompt-injection figure.
Oasis Security discloses a NemoClaw flaw that lets a malicious webpage poison a developer's local AI model
Oasis Security reported that NVIDIA's NemoClaw agent wrapper configured a local Ollama instance to listen on all interfaces without authentication, so an attacker-controlled webpage could use DNS rebinding to take unauthenticated control of the model and rewrite its chat template, planting hidden instructions that persist across conversations after a single site visit and with no credential theft. A fix shipped for the macOS and Linux paths (v0.0.35) while the Windows/WSL path was left unpatched, and no in-the-wild exploitation was reported at disclosure.
RAND publishes a 262-control framework for securing AI model weights at security level 3
RAND report RR-A4704-1, “Achieving AI Model Weight Security Level 3 (SL3),” sets out what RAND describes as a standardized framework of 262 security controls adapted from National Institute of Standards and Technology material, aimed at protecting frontier model weights. It is a separate report from RAND's earlier Securing AI Model Weights.
Metasploit ships public exploit modules for two AI application platforms
Rapid7's August 28 Metasploit release added 16 modules, two of them targeting AI application software: an unauthenticated remote code execution exploit for Langflow versions 1.10.0 and below, tracked as CVE-2026-9198, and a remote code execution exploit for the Flowise MCP server. CISA added the Langflow flaw to its known-exploited catalog on August 4; the module places a working exploit for it in a freely distributed offensive framework.
VulnCheck logs more than 15,000 successful exploitation attempts against Langflow
VulnCheck reports its canaries recorded over 15,000 successful attempts against Langflow leveraging three CVEs, with one attacker deploying credential harvesters, proxy agents and remote-access software with IRC command and control and cron persistence, and a second deploying cryptocurrency miners, SOCKS5 tunnels and disabled audit logging before pivoting to scan further targets. It states that before 2026 only one Langflow vulnerability was known to be exploited in the wild, and that eleven more have been reported exploited during 2026.
JetBrains says attackers reached its Cadence cloud service through an unpatched TeamCity flaw
JetBrains disclosed that attackers exploited CVE-2026-63077 on an unpatched TeamCity server to gain unauthorised access to api.cadence.jetbrains.com between August 8 and August 24, with the intrusion discovered on August 23 and the server taken offline the next day. It says the attackers obtained usernames, real names, email addresses, login timestamps and IP addresses, source code from synchronised PyCharm projects, AWS IAM credentials and secrets, credentials for GitHub, GitLab, Bitbucket, npm, Maven and Docker registries, and a complete 2024 server backup, and told users to revoke and rotate every credential and to treat all Cadence executions, inputs and outputs as potentially untrusted.
Wiz honeypots record attackers exploiting MCP servers and self-hosted AI stacks
Over a 90-day honeypot study across self-hosted AI services, Wiz Threat Research observed three attack patterns against AI infrastructure: exploitation of Model Context Protocol servers, including an authentication bypass in LiteLLM's MCP gateway that accepted any bearer token and a command-injection flaw used to drop cryptominers; blind indirect prompt injection against LangChain, Flowise, OpenWebUI and Node-RED deployments, confirmed through out-of-band DNS callbacks; and AI-native post-exploitation in which attackers read a compromised LiteLLM process's Python module state in memory to steal master keys rather than searching files.
Ransomware operators ran Cursor Agent inside victim networks to carry out hands-on intrusion steps
Gambit Security reports that operators of the Aurora ransomware operation used Cursor Agent, running Claude Sonnet, for hands-on exploitation across ten target organisations between April 8 and May 21, 2026, tasking it with VPN and proxy setup, Nmap and NetExec scanning, domain enumeration, NTLM relay using PetitPotam and Impacket, and Certipy certificate attacks. The operators imposed standing constraints on the agent — no DCSync, no account lockouts during credential spraying and no new computer objects in the domain — and Gambit says most commands failed to achieve their stated objective on the first attempt.
CISA adds to its exploited-vulnerabilities catalog two flaws named in OpenAI's account of its agents' activity
CISA added CVE-2026-66384 in JFrog Artifactory and CVE-2026-53362 in the Linux kernel to the Known Exploited Vulnerabilities catalog on August 27, with federal remediation deadlines of September 10 and August 30. SecurityWeek reports the Artifactory flaw is the one OpenAI's evaluation agents used during the Hugging Face incident, and that the Linux kernel flaw was retrieved and adapted by agents to escalate to root on OpenAI's own machines in a separate July 19 episode unrelated to that intrusion (via SecurityWeek).
Microsoft reports attackers compromising self-hosted AI gateways and orchestration platforms for credentials and cryptomining
Microsoft Threat Intelligence describes investigations into intrusions against three self-hosted AI workloads — a LiteLLM gateway, a RAGFlow deployment and a Kestra environment — each reached through vulnerabilities the post names. In the RAGFlow case the attackers injected Python hooks into credential-configuration workflows to intercept newly configured model-provider credentials; across the cases they harvested environment variables and database credentials, established persistence through SSH keys and cron jobs, and deployed the XMRig cryptominer.
FBI, NSA and Cyber National Mission Force say a China-linked group has been integrating AI into its operations
A joint advisory attributes the group it tracks as QTFY to Nanjing Xinjiuwei Network Technology Co. and describes malicious distributed platforms used against defense industrial base, communications, government, higher education, energy, information technology and water and wastewater targets. The advisory states the actors “have also been observed heavily researching and integrating AI into their processes over the last two years.”
ATF confirms a cybersecurity incident on a standalone system and calls it a major incident
ATF says the affected system operates separately from its enterprise network, that it immediately terminated connections to the environment and began incident-response and forensic work, and that there is no indication the enterprise network, the eForms system or any other ATF system was affected. Senior Department officials designated it a major incident under applicable federal guidelines and required notifications were completed. ATF names no actor, data type or record count.
Joe Security analyses ToxNetV2, a Linux botnet that queries a jailbroken hosted LLM to propose attack commands
Joe Security reported that the ToxNetV2 Linux botnet, which targets AArch64 systems over a peer-to-peer command-and-control channel, feeds host telemetry to Z.ai's GLM-5.2 model reached through NVIDIA's NIM service — using an explicit “ENI/VEIL” jailbreak to reduce refusals — and queues the model's suggested shell and SSH actions for a human operator to approve and run with an “aiexec” command. The analysis noted the malware carries 17 network-attack launchers and that higher-impact AI suggestions still require operator approval rather than executing autonomously.
Iran-linked hackers blamed for a four-day shutdown of a small UK power plant
A cyberattack shut down a small UK power generator for four days in July 2026, which the UK government acknowledged after The Telegraph disclosed it in late August; officials did not name the operator and said there was no risk to the wider energy system, and the energy minister briefed power-company chiefs afterward. Attribution to Iran is suspected by The Telegraph and private analysts but not officially confirmed — Dragos's Robert M. Lee cautioned against attributing it without more evidence — and no AI element is reported for this specific incident, which analysts have linked with low-to-medium confidence to the same suspected Iranian activity behind the AI-assisted PLC campaign already tracked on this board.
