New IronWorm Malware Hits 36 Packages In npm Supply-Chain Attack

A new npm supply-chain attack has infected 36 packages with Rust-based infostealer malware called IronWorm. According to BleepingComputer, the malware "targets 86 environment variables (key-value pairs) and 20 credential files that may contain OpenAI, AWS, Anthropic, and npm credentials, vault configuration files, SSH keys, and Exodus cryptocurrency wallet files." From the report: According to researchers at supply-chain and devops company JFrog, IronWorm is written in Rust, hides behind an eBPF kernel rootkit, and communicates with the operator over the Tor network. The Rust-based malware self-propagates by using stolen credentials for publishing on npm; this includes secrets associated with npm's Trusted Publishing workflow. Once it compromises a developer or CI environment, it can publish trojanized versions of packages owned by the victim, which then infect additional developers and CI systems. This behavior is conceptually similar to Shai Hulud, which had its code published on GitHub recently. Although JFrog researchers did not find a clear connection between IronWorm and Shai Hulud, they observed the same commit names in both supply-chain attacks. This opens the possibility that the new malware is an evolution of TeamPCP's payload, since IronWorm appears to be "a custom, carefully built implant from an operation with its own infrastructure." [...] The company provides a list of all impacted package names and their versions in the report and recommends that developers upgrade to fixed releases, rotate their keys, and enable two-factor authentication (2FA) for all accounts. At the same time, Endor Labs and StepSecurity have spotted a very similar but distinct attack involving a JavaScript-based malware named binding.gyp, performing registry poisoning and GitHub Actions infection, unfolding during the same time-frame.
