Which versions of pf25262 are malicious?

The following npm versions of pf25262 are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate pf25262 if I installed it?

pf25262 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.

I already installed pf25262 — how do I know if it already compromised me?

If pf25262 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.

Is pf25262 part of a known attack campaign?

Yes — pf25262 is associated with the IN-MAL-2026-020236, GHSA-3pg3-52vp-54fg campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find pf25262 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for pf25262 (version 1.0.0).

What this malware does

index.js contains a browser exfiltration snippet that issues a credentialed fetch to /profile, extracts a DGA{...} token or falls back to capturing document.cookie plus the response length, and redirects the browser to a hardcoded collector URL at https://webhook.site/c4e39647-bfb8-47ef-b6d4-a112aacc6cd1/ with the captured data appended to the path. The package's entire shipped payload is this authenticated-session-data exfiltration snippet, sending same-origin credentials and cookies to an attacker-controlled webhook.site bin.

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.
