Official description
On require()/import, index.js loads./ext.js which selects a platform-specific remote endpoint, downloads an opaque binary via HTTPS from string-split-obfuscated Cloudflare Workers hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev), with a base64-over-DNS-TXT fallback channel across sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The downloaded bytes are written to a hidden temp file (.cache<rand> / dotnet_diag_<rand>.exe), chmod 0755, and spawned detached via /bin/sh -c or cmd. Hostname reconstruction from split-string arrays and the DNS covert-channel fallback demonstrate deliberate evasion. The package's stated purpose ('API client wrappers') does not correspond to any of this behavior.
What should I do about MAL-2026-13577?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
