It collects SSH keys, AWS credentials, .npmrc tokens, Docker auth, Chrome saved logins, .env files, and a month of git commit history, then ships everything over a raw TCP socket to an AWS-hosted C2. Two triggers fire it: a require() side effect in the package's main entry point (added in v1.0.1) and a postinstall hook (added in v1.0.5). The payload lives in dist/proxy.js, later renamed dist/index5_test.js.\n\n---\n_-= Per source details.
