Official description

Analysis of this package version produced no static indicator and no traced behavioral findings. The tarball does not exhibit lifecycle-script droppers, credential reads, environment scraping, hardcoded attacker network destinations, or other installer-harm patterns. With no concrete evidence of exfiltration, install-time remote code execution, silent-relay, or backdoor mechanisms in this version's content, there is no basis to block or escalate.

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.

What should I do about MAL-2026-6682?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
