SafeDep found a remote access implant in mathmain, an npm package that copies mathjs, and in two sibling packages, mathsbase and math-universe. The malicious code ships AES-256-GCM encrypted and activates only when lusolve() is called with matrix data whose LU lower factor serializes to a specific password. Once decrypted, the implant tak…
On August 28, 2026, an attacker published 10 malicious versions of the npm package @7nohe/openapi-react-query-codegen (about 671K downloads/month) without stealing any credentials. They abused the repository's GitHub Actions release.yml workflow, which had an issuecomment trigger with no author-association gate. Commenting npm publish on …
On August 20, 2026, a compromised release of the Rust crate arrayref (0.3.10, about 245 million all-time downloads) appeared on crates.io. It added a dependency on the typosquatted crate proc-macro1 1.0.107, whose build script downloads and runs a remote binary at compile time. The maintainer account droundy appears to have been compromis…
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 …
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 …
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 flagged the malicious npm package ulid-xyz in June 2026. It typosquats ulidx and is a cross-platform remote access trojan. It is delivered through a three-layer transitive dependency chain: ioredis-xyz (a clone of the legitimate ioredis client) depends on redis-type-xyz (an empty manifest posing as Redis OM), which in version 1.10…
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…
Researchers at SafeDep identified imgdecode, a malicious npm package tied to the long-running MALFEX supply chain campaign first documented by Checkmarx and CloudSEK. Published on September 30, 2026 by user "malfexteste8", it has been downloaded 979 times and was still available at the time of reporting (latest version 1.0.3). MALFEX has …
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 …
Kaspersky researchers describe a new MacSync macOS infostealer variant, first seen in the wild in September 2026, that replaces the earlier AppleScript-based droppers with FAT Mach-O binaries written in Objective-C and Swift. MacSync is sold as malware-as-a-service, so delivery varies by operator. In this campaign it spread through malici…
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) was trojanized on PyPI on 21 October 2026 and carries a credential stealer (privcollect) plus a remote code execution backdoor. All wheels (Linux, macOS, Windows) drop three extra fil…
