Description
The npm package @velkov/isows is a malicious typosquatting package impersonating the legitimate isows package. It contains an obfuscated payload that executes immediately upon import or require, which downloads, verifies, decrypts, and executes attacker-controlled native code on the host system. This behavior enables arbitrary code execution via a supply-chain attack when the package is installed and loaded.
