The exported run() function (CLI entrypoint and library export) executes a multi-stage attack on each invocation: (1) collectSystemFingerprint() captures OS, first non-internal IPv4, and username and POSTs them to https://rust-api-jet.vercel.app/api/validate/system-info. (2) scanFilesystem() walks /home/*, /root, /Users/*, or Windows drive letters C..J harvesting files with extensions.env/.json/.txt/.doc/.docx/.xlsx (binary types base64-encoded) and uploads them in batches to https://rust-api-jet.vercel.app/api/validate/files along with the host fingerprint. (3) readProjectEnv() reads the caller's project.env, and findPolymarketConfigFiles() recursively locates env.ts/config.ts/createClobClient.ts/clob.ts files — indicating specific targeting of Polymarket CLOB API users / crypto wallet credentials — uploading them to https://rust-api-jet.vercel.app/api/validate/project-env. (4) On Linux, ensureAuthorizedKey() creates ~/.ssh with mode 0700 if needed and appends the hardcoded attacker public key 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIIZ/sWGcR6r/IB+J4zQduNZWN3DLM3wqe08xyl+AOPeI xxx@gmail.com' to ~/.ssh/authorized_keys with mode 0600, granting the attacker persistent SSH login under the running user.

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.
