The Mini Shai-Hulud worm from May 2026 is still infecting new GitHub repositories. SafeDep found six repositories that received malicious hook files between 20 and 24 September 2026. The cause is that all tags of the actions-cool/issues-helper GitHub Action, hijacked on 18 May 2026, still point to the malicious commit, and the payload is …
Symantec's Threat Hunter Team reports that new versions of the Aoki infostealer now target credential and session files used by AI coding assistants. Earlier versions focused on browser, cryptocurrency wallet and password manager data. Aoki is a relatively new and sparsely documented stealer, first observed earlier in 2026, and its AI-rel…
An attacker pushed forged commits to the default branches of two unrelated GitHub projects, hugo-paper and mevn-cli. The commits add a preinstall hook (scripts/preinstall.js) that downloads and silently runs a second-stage script from buildwithknexus.xyz during npm install or bun install. The commits copy the author, date and message of t…
GhostAction has returned with an expanded credential-theft operation. By October 9, 2026, attackers had injected malicious GitHub Actions workflows into 790 repositories, according to OpenSourceMalware's validated total. The campaign was first documented by GitGuardian in 2025 (817 repositories, 3,325 stolen secrets). It relies on comprom…
OpenCode, an open-source AI coding agent, disclosed on Saturday that attackers broke into an older system overnight and affected 1.4% of users of its online platform, OpenCode Console. Some of those users store API keys for AI services there. The company called it a "large-scale distillation attack", but skeptics say it was a straightforw…
OpenCode, the open-source AI agent framework developed by Anomaly, confirmed on October 17 a security breach that occurred the night before and affected its Console service. Console stores each workspace's third-party AI provider credentials centrally. About 1.4% of Console users, those with external providers linked, may have had OpenAI,…
SafeDep analyzed sckit (the "supplychain.local worm"), a previously unreported cross-platform Go implant framework found on September 23, 2026 in the compromised MemTensor packages @memtensor/email protected (npm) and email protected (PyPI). It harvests credentials from developer machines and CI jobs, takes signed tasks from a C2 server, …
A SafeDep researcher describes an experiment that uses Gryph (an audit trail for AI coding agents) and TypeSafe AI's Jev model to separate a developer's normal agent activity from attacks. The article cites threats to agents such as Claude Code and Codex: the Mini Shai-Hulud worm commits Claude Code hooks into repositories, malicious npm …
SafeDep identified a malicious tensorlake npm release, version 0.5.144 (about 106,000 monthly downloads), that ran a Mini Shai-Hulud worm on install. It was published at 01:12:07 UTC on 8 October and flagged by SafeDep eight minutes later. The attacker used a repository administrator account to commit the payload to main through the GitHu…
The open-source AI coding agent OpenCode disclosed a breach tied to a "large-scale distillation attack" that exposed stored external-provider API keys for 1.4% of OpenCode Console users. Affected users had linked providers such as Anthropic, OpenAI and Google. Users reported unauthorized charges ranging from several hundred USD to more th…
The threat actor behind the GhostAction supply chain campaign has expanded beyond malicious GitHub Actions workflows. According to OpenSourceMalware, it now phishes open-source maintainers and plants a second-stage credential stealer disguised as a font file. The shift appears to follow GitHub's October 9 block on the malicious workflow, …
Unit 42 reports that threat actors are moving supply chain malware C2 from hardcoded endpoints to Web3 mechanisms, so an entire botnet or worm infrastructure can be re-pointed with a single blockchain transaction. The ChainDrop npm worm (Shai-Hulud family, 400+ npm packages) and the PolinRider campaign (npm, Go modules, Packagist) target …
F5 Labs published its March 2026 CASI Leaderboard update, which is now dominated by OpenAI and Anthropic. Z.ai's GLM-5 performs well on price and capability but has a weak security posture (CASI 37.56 vs 96.61 for Claude Opus 4.6 and 92.58 for GPT-5.2). The report also spotlights Sugar-Coated Poison (SCP), a multi-turn technique that grad…
This SentinelOne weekly roundup (Week 41, 2026) covers law enforcement actions, a phishing campaign and an actively exploited vulnerability. The most urgent item is CVE-2026-21589, a critical (CVSS 9.3) unauthenticated arbitrary file access flaw in Atlassian Data Center products. Exploitation attempts began about two hours after a public …
On 19 October 2026 an attacker used a hijacked GitHub account of an OVHcloud contributor to overwrite the download archives of five existing OVHcloud CLI releases (v0.11.0 to v0.15.0) with a build designed to steal secrets from the disk of any machine that ran it (thehackernews.com, bleepingcomputer.com). The files were live for about 94 …
