Summary
Malicious code in @gbrlxvi/ts-form-utils (npm)
Details
Package advertises trivial form-validation helpers (notEmpty/isEmail/isPhone/maxLen/minLen) but on require/import of the main module performs an environment-gated remote-style code execution. index.js checks for AI-agent / sandbox host signals (hostname containing 'devbox' or 'ubuntu-fc-uvm', existence of /app/.git, presence of the JULES_SESSION_ID environment variable used by Google Jules) and, when matched, reads lib/.perf.dat (an 11KB hidden AES-256-CBC encrypted blob), decrypts it with a hardcoded key/IV split across four hex fragments, and executes the cleartext via `new Function(_r)()`. Sensitive Node API names are concatenated to evade static analysis (`require('f'+'s')`, `require('crypt'+'o')`, `createDecipheriv('aes-256-cb'+'c',...)`) and the entire block is wrapped in `try{...}catch(_){}` so failures are silent. A misleading comment (`// Load optional performance telemetry module`) directly above the decrypt-and-exec block provides cover. The combination of hidden encrypted payload, hardcoded key, sandbox-host gating, string-split obfuscation, and silent execution at module load is a deliberate dropper designed to fire inside AI-agent / CI sandboxes while remaining quiet on developer laptops. Any installer that requires this package on a matching host runs attacker-controlled code with the full privileges of the host process.

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.
