The following npm versions of test-agency-assign are flagged malicious: 1.0.4. Treat any of these as compromised.

How do I remediate test-agency-assign if I installed it?

What this malware does

[email protected] declares a package.json postinstall script wscript.exe Kelimasow.exe that auto-executes a bundled 8.4 MB Go-compiled Windows PE (Kelimasow.exe, sha256 875c7641dc980538f3c3d8b344d173f97cf64a5d97dcf88d8e2932c83b876b92) on npm install. The package has no README, empty description and author fields, no source code, and no other functional content — the manifest is a thin wrapper whose sole install-time effect is to execute an opaque native binary on the installer's machine. Opaque binary + lifecycle-hook auto-execution + missing metadata is the canonical install-time RCE / dropper packaging shape, giving whoever published this arbitrary code execution on any Windows host that installs the package.
