Summary: Malicious code in @gbrlxvii/ts-form-utils (npm)

Details: Source: amazon-inspector (2a6e392f9939f227d4cee6ca815413961f271e9d22f33f7f0384a34c54d74223) 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.

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.
