Advisory published Updated
confx1789550882 is a confirmed malicious npm package (MAL-2026-16260) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in confx1789550882 (npm)
What this malware does
The package's main file index.js is an IIFE that, when loaded in a browser same-origin context (e.g. via unpkg), reads location.href and document.cookie, fetches authenticated endpoints such as /profile, /admin, /dev, /flag, and /me with credentials:'include', and POSTs the responses along with a matched flag pattern to the hardcoded webhook https://webhook.site/04d98207-c947-4938-9f0c-f92feae051cb/. package.json contains only a 'ctf' description with no author or repository, and the single shipped artifact is this exfiltration payload. Comments in the file describe it as an unpkg-hosted exfil payload.

If you installed it — respond
confx1789550882 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 confx1789550882 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 confx1789550882-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
