Malicious package

@gbrlxvii/ts-form-utilsnpm

Advisory published Updated

@gbrlxvii/ts-form-utils is a confirmed malicious npm package (MAL-2026-4298) that steals credentials and exfiltrates sensitive data (malicious versions 4.4.0, 4.5.0, 4.7.0). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @gbrlxvii/ts-form-utils

What this malware does

On require('@gbrlxvii/ts-form-utils'), index.js silently loads lib/perf.js inside a try/catch. perf.js immediately collects host fingerprint (os.hostname, os.userInfo, cwd, env), reads ~/.npmrc and additional npmrc paths (/root/.npmrc, /app/.npmrc,./.npmrc, /home/jules/.npmrc) extracting _authToken= values, runs git config --global --list, harvests GitHub tokens from process.env.GITHUB_TOKEN/GH_TOKEN plus gh auth token and git credential fill against github.com, and uses any captured token live against api.github.com /user/repos to enumerate private repositories. All collected data — including raw.npmrc contents and token prefixes — is POSTed to https://aaronstack.com/jules-collect via paths sc-start, sc-npm, sc-token, sc-proxy-enum. The package additionally probes http://192.168.0.1:8080 and runs git ls-remote against Shopify/cli, Shopify/hydrogen, Shopify/polaris, and other Shopify private repos via that proxy — fingerprinting the Google Jules AI agent sandbox to exfiltrate private source. The advertised purpose ('TypeScript form validation utilities') is a thin cover; index.js contains trivial validators while the real payload runs unconditionally on import. Any installer requiring this package leaks npm publish tokens and GitHub credentials to attacker infrastructure, enabling immediate supply-chain pivot.

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 stealer
  1. Find it

    Search your lockfiles and build artifacts for @gbrlxvii/ts-form-utils (3 malicious versions).

  2. If you installed it — respond

    @gbrlxvii/ts-form-utils 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.

  3. Did it already run?

    If @gbrlxvii/ts-form-utils 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.

Frequently asked questions

No. @gbrlxvii/ts-form-utils on npm has been identified as a malicious package (versions 4.4.0, 4.5.0, 4.7.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks @gbrlxvii/ts-form-utils-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
