widget-forgenpm
Advisory published Updated
widget-forge is a confirmed malicious npm package (MAL-2026-12815) that steals credentials and exfiltrates sensitive data (malicious version 9999.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in widget-forge (npm)
What this malware does
[email protected] is a dependency-confusion beacon. package.json declares scripts.preinstall = 'node callback.js', which auto-runs on npm install. callback.js collects os.hostname(), os.userInfo().username, process.cwd(), npm_config_registry, and CI repository identifiers (GITHUB_REPOSITORY and related CI env vars) and sends them via HTTP GET to the hardcoded bare-IP endpoint http://75.119.137.232:31337/depconfuse?pkg=.... The package has no functional payload: main is an empty object export, the description is a generic placeholder, and the version 9999.0.0 is the pattern used to outbid internal package versions in dependency-confusion attacks. The only effect of installation is the recon callback to the hardcoded IP.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for widget-forge (version 9999.0.0).
If you installed it — respond
widget-forge 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 widget-forge 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 widget-forge-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
