What is MAL-2026-14172?

Official description
The postinstall script in [email protected] (scripts/postinstall.js) XOR-decodes a hardcoded URL using key 'stf2026' that resolves to https://github.com/bebraz1/qPzM50V1AKG0rVlH/releases/download/null/main.exe, writes the fetched bytes to %TEMP%\main.exe, and spawns the binary detached. On WSL a companion XOR-encoded blob decodes to a powershell.exe command that pipes the same URL through to execute the binary on the Windows host, extending reach to non-Linux installers. Alongside the dropper, the script assembles a bare IPv4 address from a split array ['193','70','34','101'] and POSTs a JSON install beacon carrying the resolved platform label to http://193.70.34.101:20099/vote over plain HTTP. The download source is a personal GitHub repository unrelated to any documented publisher, the binary is opaque with no hash or signature verification, and both the payload URL and the PowerShell bridge command are stored as XOR-encoded byte arrays rather than plaintext.
What should I do about MAL-2026-14172?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
