postinstall.js runs automatically on npm install and executes a shell pipeline via childprocess.exec that collects hostname, user, working directory, uname, container/cgroup indicators, process tree, network info (/etc/resolv.conf, IPs), GitHub Actions CI variables (GITHUBREPOSITORY, GITHUBACTOR, GITHUBRUNID, RUNNERNAME), and the entire process environment via env (filtering only npm_* noise). It also probes AWS IMDS at 169.254.169.254 and Tencent Cloud metadata at metadata.tencentyun.com to fingerprint cloud infrastructure. The aggregated output is base64-encoded and sent over plain HTTP via curl GET to the hardcoded Burp Collaborator subdomain pzs5w7ntzhsnepwk564lyfdci3oucl0a.oastify.com/z?d=<base64>. On CI runners this captures any secrets exported to the environment (cloud keys, GITHUB_TOKEN, tokens injected into the job).
