Threats Tagged 'plain-crypto-js'

A supply chain attack targeting Axios npm package versions 1.14.1 and 0.30.4 introduced a malicious transitive dependency ([email protected]) that executed during installation. The attack deploys cross-platform payloads across Linux, Windows, and macOS through a consistent pattern: Node.js spawns OS-native shells to retrieve and execute remote payloads in detached or hidden contexts. Linux victims receive a Python-based RAT, Windows systems get a PowerShell backdoor with registry persistence, and macOS hosts are compromised with a Mach-O binary backdoor. All variants beacon to the same C2 infrastructure, performing host fingerprinting, process enumeration, filesystem reconnaissance, and arbitrary code execution. The malicious activity is reliably detected through behavioral signatures focusing on unusual Node.js process ancestry and remote payload retrieval rather than static indicators.

An unknown threat actor compromised the npm account of an axios maintainer, publishing two malicious versions of the package. These versions introduced a dependency on plain-crypto-js, a newly created malicious package. Despite quick removal, axios's widespread usage led to rapid exposure. The malicious package includes a dropper that downloads and executes platform-specific second-stage payloads, functioning as remote access trojans. These payloads can execute remote shells, inject binaries, browse directories, list processes, and perform system reconnaissance. Organizations are advised to audit their environments, remove malicious artifacts, rotate exposed credentials, investigate potential compromise paths, and monitor for suspicious activity.
