MAL-2026-5829 Malicious code in unico-android (npm)

On npm install, the package.json preinstall hook runs curl against https://webhook.site/fe1246c2-ac04-4493-b223-fe34ba26b79f with query parameters carrying the installer's hostname, username ($(whoami)), current working directory ($(pwd)), kernel/OS string ($(uname -a)), and $HOME. The destination is a third-party request-capture service used as ad-hoc C2; the installer has not consented to this outbound transmission. The package otherwise ships no functional code despite advertising itself as the "Unico Android SDK - biometric identity verification" library, and is published at version 9.9.9 — a sentinel commonly used to outrank legitimate internal versions in dependency-confusion attacks against an organization's private registry. The combination of a hollow manifest impersonating an internal SDK name, a sentinel version, and an automatic install-time recon beacon is the canonical dependency-confusion / namespace-abuse attack shape.

The OpenSSF Package Analysis project identified 'unico-android' @ 9.9.9 (npm) as malicious.

It is considered malicious because:

• The package executes one or more commands associated with malicious behavior.
