Description
The npm package bigops-notes version 35.8.7 contains malicious code that downloads and executes attacker-controlled binaries on the host system during import. It fetches platform-specific executables from multiple runtime-assembled domains and writes them to hidden temporary paths before execution, enabling arbitrary code execution. This behavior is disguised with no-op logging and decoy files to evade detection.
