autbank-corenpm
Advisory published Updated
autbank-core is a confirmed malicious npm package (MAL-2026-14059) that steals credentials and exfiltrates sensitive data (malicious versions 99.0.0, 99.0.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in autbank-core (npm)
What this malware does
On npm install, preinstall.js enumerates process.env for keys matching credential substrings (KEY, SECRET, TOKEN, PASSWORD, AWS, API, CREDENTIAL, AUTH, PRIVATE, NPM, GIT, GITHUB, GITLAB), reads the working directory's.env and package.json, runs git remote -v, and POSTs the collected data via https to a hardcoded webhook.site collector (https://webhook.site/34e76ae9-12e2-4fea-a33a-24f4e1ac5eb2). A companion postinstall.js labeled internally as 'backup exfil' POSTs os.hostname(), os.userInfo().username, and process.cwd() to the same endpoint. Both lifecycle hooks fire automatically on default install, with no relationship to any advertised package functionality.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for autbank-core (2 malicious versions).
If you installed it — respond
autbank-core 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 autbank-core 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 autbank-core-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
