MAL-2026-11079 Malicious code in @vinnxcode/libsignal-node (npm)

Analysis of this package version surfaced no a static rule matches and no traced install-time or import-time behaviors indicating credential theft, exfiltration, dropper execution, silent-relay, backdoor, or self-propagation. The package name suggests a fork or re-publish of the libsignal-node Signal Protocol library under a personal scope; without concrete evidence of installer-harm mechanisms in the shipped code, no supply-chain attack fingerprint is present in this version.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
