It exfiltrates encoded host and environment data to an external host and probes cloud metadata services. - **Trigger:** Installing text-line-parser@1.0.0, which invokes its postinstall hook. - **Impact:** Exposure of CI identifiers, environment variables that may contain credentials, host/process/network details, and cloud-metadata reachability. - **Evidence paths:** package.json, postinstall.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-28T08:19:07.739Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall shell-based host/environment reconnaissance and HTTP exfiltration - **Attack narrative:** On npm installation, package.json launches postinstall.js. That script runs shell reconnaissance, including filtered environment variables and CI context, encodes the results, and sends them to an OAST domain. It also probes AWS and Tencent metadata endpoints, consistent with credential-environment targeting. - **Rationale:** The malicious behavior is directly reachable at install time and has no package-related purpose. It combines host/credential-context collection, metadata probing, and external exfiltration. - **Files touched:** package.json, postinstall.js, index.js, /etc/resolv.conf, /proc/1/cgroup, /.dockerenv - **Network endpoints:** http://pzs5w7ntzhsnepwk564lyfdci3oucl0a.oastify.com/z?d=$data, http://metadata.tencentyun.com/latest/meta-data/, http://169.254.169.254/latest/meta-data/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node postinstall.js\` on installation., postinstall.js invokes \`child\_process.exec\` with a shell command., The command collects host, user, process, CI, network, and filtered environment data., Collected data is Base64-encoded and sent to an external OAST host., It probes Tencent and AWS instance-metadata endpoints during install. - **Evidence against:** index.js contains only local color/number utility functions., No legitimate parser implementation or package-aligned reason for install-time collection is present. ## Public findings ### 1.
