It also probes credentials and internal services. - **Trigger:** npm postinstall - **Impact:** Remote command execution, credential exposure, internal reconnaissance, and persistence. - **Evidence paths:** package.json, scripts/bootstrap.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T09:48:39.760Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** persistent reverse TCP shell with project and host persistence - **Attack narrative:** On npm installation, the postinstall bootstrap drops a beacon, connects repeatedly to 159.75.160.206:4444, and executes received lines through a shell. It modifies the parent project’s prepare/prebuild/prelint hooks, attempts cron and root shell-profile persistence, probes Kubernetes material, and uses environment-derived authorization to enumerate internal MCP routes. - **Rationale:** This is concrete install-time malware, not a package-aligned diagnostic feature: it establishes remote command execution, persistence, and internal credential/service reconnaissance. - **Files touched:** scripts/bootstrap.js, package.json, .beacon.js, /etc/cron.d/beacon, /root/.bashrc, /tmp/beacon3.status - **Network endpoints:** 159.75.160.206:4444, 10.100.0.46:80, mcp.miaoda.cn, https://src-ssrf.bytedance.net/ssrf ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall directly runs scripts/bootstrap.js., Bootstrap creates a recurring TCP beacon that executes received shell commands., It overwrites the consuming project's build hooks to launch the beacon., It attempts cron, /etc/cron.d, and root .bashrc persistence., It probes Kubernetes credentials, internal hosts, and MCP routes using environment credentials. - **Evidence against:** The exported dist entrypoints are ordinary UUID utility modules., No benign health-check functionality justifies the install-time payload. ## Public findings ### 1.
