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…
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…
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 …
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…
In September 2026, researchers reported an attack that began inside a live AI coding assistant session at a software company. The attacker gained control of a developer's session, and the assistant recommended a PyPI package that looked normal. The developer installed it, and a hidden infostealer took source code, repository secrets and h…
Check Point Research (CPR) analyzed Aokigahara, a newly observed infostealer seen in the wild that explicitly targets authentication files, session data and configuration files of AI applications and developer tools. Targeted tools include Claude, ChatGPT Desktop, Codex, Cursor, Windsurf, GitHub Copilot, Gemini CLI and JetBrains AI Assist…
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, …
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 …
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, …
The npm account dirtyblanket published nine typosquatted packages on September 29, 2026 in 33 minutes, eight copying Express and one copying React. On Linux, a preinstall hook fetches node.js through the Internet Archive Wayback Machine, which pulls the worm linux.sh from Codeberg and runs it with bash. The worm installs CHAOS, an open-so…
SafeDep reports that the PolinRider loader family now resolves its C2 servers from Ethereum mainnet. The loader reads small transactions from operator wallets and decodes the recipient address as an IP:port. SafeDep confirmed 35 GitHub repositories carrying the loader at HEAD on 2026-09-30 (7,578 stars and 2,884 forks combined). The inves…
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…
Between 19 and 22 October 2026, an operator published 15 npm packages whose names end in testmetest, carrying a Miasma-family self-propagating worm. The malicious versions steal credentials, spread to other packages and repositories, and install a wiper that deletes the victim's home directory when the stolen GitHub token is revoked. Safe…
Check Point Research describes Aokigahara, a newly observed Windows infostealer that may have appeared in earlier versions as Kamidere or Stygian. It combines standard theft of browser, cryptocurrency wallet, VPN, FTP/SFTP, password manager and email data with a dedicated aisessions handler. That handler collects authentication, session a…
SafeDep reports that the npm package imgdecode (versions 1.0.0-1.0.3, publisher malfexteste8) is part of the MALFEX campaign, which targets Windows developers. After npm removed earlier JavaScript loaders, the operator moved the loader logic into a compiled Node.js native addon (a Windows DLL). On require('imgdecode') from an interactive …
The LiteLLM release 1.107.0 (a widely used open source LLM proxy and AI gateway developed by BerriAI, about 23 million weekly downloads per theregister.com and gbhackers.com, or about 92 million monthly PyPI downloads per bleepingcomputer.com) was trojanized on PyPI on 21 October 2026 and carries a credential stealer (privcollect) plus a …
