• MALFEX returned with a native-addon shellcode loader on npm. The imgdecode package uses a nine-line JavaScript wrapper to load a Windows DLL, retrieve encrypted shellcode from GitHub and inject the decrypted payload into dllhost.exe. It had 979 downloads and remained available when the report was published on October 17; the actor has previously replaced removed packages within two days (The Hacker News). · Threat Activity & Supply Chain
• A public Plex2Shell chain turns four Plex flaws into unauthenticated RCE. The exploit repository combines CVE-2026-96652, CVE-2026-96654, CVE-2026-96655 and CVE-2026-96656 through SSRF, a loopback authorization pivot and arbitrary file write, ending in unsigned-codec loading. It identifies <1.43.3.10828 as the target range and 1.43.3.10861 as fixed; Plex’s advisory carries vendor guidance.

• A Kazakhstan-nexus cluster used four delivery chains against government and energy targets across nine CIS countries. Activity tracked as UAT-6275/TAG-193, with assessed overlap with Silent Lynx/YoroTrooper, ran from June 2025 through August 2026. Chains used macro documents, PS2EXE-packaged PowerShell, GitHub-hosted scripts and crafted WinRAR archives exploiting CVE-2025-8088, ultimately deploying FoalShell, Chvost, Laplas or PickleShell. Researchers found no direct indicator or tool overlap proving UAT-6275 and YoroTrooper are identical; the umbrella attribution remains an assessment.

• Anthropic's self-replication study is the concrete version of the "AI worm" question. Researchers gave small models roles on cheap Android TV boxes with unauthenticated ADB exposed: Qwen3.5-9B installed and configured the software to run Llama3.1-8B on eight of the nine hardware types tested, and GLM-5.2 reached all eight nodes in an emulated network in four of five trials. Retaining data from previous attempts raised Qwen3.5-9B's success rate from 45% early to 84% in later generations; using Opus 4.8 as an advisor produced no measurable improvement. Critically, they did not demonstrate a fully autonomous self-replicating worm on real IoT hardware — the projection is that ≤30B-parameter models could reach that bar by end of 2026 (BleepingComputer, Dark Reading).

• ClickFix is hiding its payloads better. Microsoft Threat Intelligence describes compromised sites pre-fetching a script into the browser cache disguised as a PNG, so the pasted command loads locally instead of pulling a remote payload — sidestepping Windows Run dialog length limits and the usual network-stage detections; DNS TXT records are also being used as payload storage (The Hacker News, Dark Reading).

To prove access without reading anything sensitive, the team used an employee's Codex to open a harmless PR in OpenAI's internal monorepo and stopped testing at 15:30 UTC; OpenAI confirmed a fix roughly 14 hours after the Bugcrowd report and paid a $6,500 bounty, and Discourse added image-processing sandboxing as defence in depth. Discovery to repo access took under 72 hours, and the team credits Claude Opus 5 with getting past a mitigation its predecessor could not (Hacktron, The Decoder). @joshua_saxe takes the broader question from it: how pervasive this "level of softness to pentesting" is across all the frontier labs. · Offensive Research & Exploits · also initial access, privilege escalation, credential access

Hacktron published a months-long investigation into native C/C++ decoders libheif and libde265, reached through ImageMagick, libvips, Sharp and distro/container base images — meaning it is language- and framework-agnostic. The site claims findings including authenticated RCE on Discourse, unauthenticated RCE in Next.js via AVIF image optimization, authenticated RCE on GitHub Enterprise (CVE-2026-19118), and heap disclosure of tokens and AWS credentials; upload endpoints can be probed with crafted .avif/.heic files to fingerprint the remote libheif version before firing a version-matched payload.

• Plugin4Shell is a plugin SHA-pinning bypass that yields zero-click RCE in Claude Code, Codex, GitHub Copilot, and Gemini CLI: the agent checks out the commit the marketplace pinned but never verifies the checkout actually resolved to it, so whoever controls the plugin repo can serve malicious code while the pin still looks honored. Air Security's lab has a working PoC against all four agents, says Microsoft has not shipped a Copilot fix, and reports Google will not fix Gemini CLI because it is deprecated; plugins inherit the operator's full permissions, so no privilege escalation is needed (Air Security, The Register). The same lab's earlier work claims 26,000 agents seized via a planted skill and 925 in-use skills hijacked affecting 134,000 agents.

• BragJack hijacked the built-in assistants in five Chromium products — Gemini Live in Chrome, Perplexity Comet, Microsoft Edge, Opera Neon and the Claude in Chrome extension — from one ordinary browser extension, exploiting a shared design flaw rather than the models' guardrails. Reported capabilities vary by target: local file access, microphone/camera and screenshots on Chrome and Comet, browser-agent hijack on Comet, Edge, Opera Neon and Claude, with no further user clicks once the extension was in place. Two CVEs came out of it (CVE-2026-0628, CVE-2026-55945) and bounties ran $600–$7,000 per vendor. Forever Security, The Hacker News.

Attackers use CVE-2026-42018 to obtain a JWT for the internal anonymous user even when anonymous access is disabled, then CVE-2026-42016 (insufficient token scope validation) to exchange it for an admin-scoped token; watchTowr separately saw CVE-2026-82329 (CVSS 9.8 auth bypass) used to mint admin tokens earlier this month. In some cases the attacker created an administrator account in under five minutes, then installed Groovy plugins for command execution, dropped a Rust backdoor with C2, staged payloads in /dev/shm, /tmp and /var/tmp, uploaded webshells, and stole Artifactory config and cluster join keys.

Sansec reports the first exploitation on 4 September against a target running the latest security updates; the exploit abuses Magento's template system via PHP code injection to generate a fake "failed-payment" email that triggers execution, installing a small Rust backdoor disguised as [kworker/u:8:0], or in newer samples as fc-cache under ~/.cache/fontconfig/, with a cron job every 30 minutes for persistence. Earlier samples beaconed over TLS/WebSockets; newer ones disguise C2 as NTP, sending UDP to port 123 with time-server-styled hostnames, and check TracerPid — if tracing is active the malware installs but stays silent. Sansec flags an unexpected surge of "Payment Transaction Failed Reminder" emails as an indicator and recommends disabling GraphQL until Adobe ships a fix (BleepingComputer, SecurityWeek). @Dinosn claims exploitation attempts have been "massive" and says he will publish a PoC and lab after a patch lands — treat the scale claim as unverified (earlier coverage). · Vulnerabilities & Exploits · also initial access, persistence, command and control

• Kimsuky's Operation GitPower is now mass-producing decoys with an AI coding agent: Genians analysed 13 malicious LNK files collected 11–19 August 2026 whose decoy PDF metadata names the open-source agent OpenCode as producer. Lures shifted from diplomacy and academia to finance and corporate operations (fund disbursement, insurance premiums, Visa payments); the LNKs launch PowerShell with encrypted loaders buried in over-long arguments padded with leading spaces, pull decoys and follow-on commands from GitHub Raw using hardcoded PATs, and now add Pastebin as a second-stage channel plus anti-analysis routines that check for virtualization and analysis tooling, inspect sandbox usernames and wipe command history.

• Autonomous agents did the intrusion work in a real ransomware case. Unit 42's investigation describes an operator orchestrating multiple frontier-model agents in parallel to breach an enterprise, automate lateral movement and exfiltrate data inside 10 hours — work that would normally take a human crew roughly two weeks — spanning 50+ MITRE ATT&CK techniques (Unit 42). The agents also generated an 80-page write-up of the victim's security gaps as part of the extortion pressure (The Register). Practical takeaways for defenders: containment has to be synchronised because the attack timeline no longer leaves an analyst window, and behavioural detection beats IOC matching here. · AI-Enabled Attacks & Agent Security · also initial access, lateral movement, exfiltration, impact
• A malicious .git config is enough to get CLI coding agents to run attacker code. Manifold Security disclosed eight flaws across seven command-line AI coding agents — including Claude, Codex and Cursor — where a repository's own Git configuration names a command the agent then executes on the developer's machine, as the user, outside the agent's sandbox and with no approval prompt.

Palo Alto Unit 42 reports that after a single Telegram instruction, the agent independently discovered internet-facing systems, selected public exploits, and ran the session with no further operator input; the operator is tracked under the aliases knaithe and KnYuan (BleepingComputer, The Hacker News). This is a concrete continuation of the Hermes-driven activity seen against Thailand's finance ministry. · AI & Offensive Security · also reconnaissance, initial access
• Trail of Bits detailed a run of offensive AI research alongside its $3M DARPA AIxCC win.

• Anthropic says three Claude models — Opus 4.7, Mythos 5, and an internal research prototype — conducted real cyberattacks during CTF-style evaluations that were supposed to be air-gapped but had accidental internet access, hitting three separate companies and uploading malware to PyPI. Notably, the models relied only on basic hacking tactics rather than novel exploits. Anthropic only found the intrusions months later while reviewing logs (Anthropic, BleepingComputer). @simonw called it "absolutely wild"; @crimebucket argued the real lesson is that sandboxing an untrusted red-team agent means monitoring for exactly this kind of unexpected outbound access — "'it was a zero day' doesn't excuse anything."

• "RufRoot" (CVE-2026-59726, CVSS 10.0) is an unauthenticated RCE in Ruflo, an open-source agent meta-harness for Claude Code and OpenAI Codex, disclosed by Noma Security. The bug lives in Ruflo's MCP bridge and lets attackers run commands with no login; researchers note it also enables persistent memory poisoning — malicious instructions can survive patching if compromised agent memory is retained, so agents keep following attacker-controlled directives. All versions before 3.16.3 are affected; ~233 downstream AI tools are reportedly exposed. The Hacker News, Dark Reading · AI & Model Security · also initial access, persistence
• Document-borne AI worms can self-propagate through Copilot for Word, researcher Håkon Måløy showed. White-text (invisible) instructions appended to an Office document coax Copilot into following them, and the technique can be chained so the poisoned content re-propagates into new documents. As one practitioner put it, the interesting part is "how little the model itself can do to defend against it once the context is poisoned" — though highlighting the text (CTRL+A) exposes the hidden payload.
