Advisory published Updated
6161test1234 is a confirmed malicious npm package (MAL-2026-2967) that steals credentials and exfiltrates sensitive data (malicious versions 0.0.0-stage, 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in 6161test1234 (npm)
What this malware does
Package [email protected] contains only two files and exhibits no install-time lifecycle scripts, no network activity, no filesystem reads of sensitive paths, and no credential handling. The name and version suffix are consistent with a throwaway test publication. No code paths that could harm an installer 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.
The OpenSSF Package Analysis project identified '6161test1234' @ 1.0.0 (npm) as malicious.
It is considered malicious because:
- The package communicates with a domain associated with malicious activity.

Credential / info stealerFind it
Search your lockfiles and build artifacts for 6161test1234 (2 malicious versions).
If you installed it — respond
6161test1234 is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If 6161test1234 was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks 6161test1234-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
