8i7pp4npm
Advisory published Updated
8i7pp4 is a confirmed malicious npm package (MAL-2026-17952) that steals credentials and exfiltrates sensitive data (malicious version 0.0.0-stage). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in 8i7pp4 (npm)
What this malware does
Package 8i7pp4 version 0.0.0-stage contains only two files and no detected behaviors of concern. There are no lifecycle scripts fetching or executing remote content, no reads of installer secrets (environment variables, SSH/AWS/npm credentials, browser or wallet stores), no outbound network calls to attacker-controlled destinations, no obfuscated payloads, and no persistence or backdoor mechanisms. The version suffix and minimal file count are consistent with a placeholder, staging, or test publication rather than functional code.
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.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for 8i7pp4 (version 0.0.0-stage).
If you installed it — respond
8i7pp4 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 8i7pp4 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 8i7pp4-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
