MAL-2026-12024 Malicious code in @keyv/test-suite (npm)

@keyv/test-suite is a shared test harness used by keyv storage adapter packages. No install-time lifecycle hooks, remote fetches, credential reads, exfiltration endpoints, or persistence mechanisms were identified in the package contents. No static or behavioral indicators of supply-chain attack were observed.

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.
