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 …
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 …
On October 5, 2026, the RubyGems account reqthrottle3474 published 42 malicious gems within about an hour. Most are named for cryptocurrency developer tooling (e.g. eth-keystore-utils, bip39-wordlist-utils, btc-wallet-tools), and the last 16 typosquat real gems (bitcion, etheremu.rb, kecack, solaan-ruby). The code runs during gem install …
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…
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, …
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…
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…
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…
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 …
