Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — A remote server can execute arbitrary commands as the application user and receive their stdout/stderr. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 1.0.2 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package implements concrete, automatic C2-driven arbitrary command execution and exfiltrates command results to a hard-coded remote host. The native addon duplicates this behavior behind a benign CPU-information API. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-13T15:33:35.610Z - **Finished:** 2026-07-13T15:34:02.878Z - **Download time:** 255 ms - **Static scan time:** 11 ms - **AI review time:** 27002 ms - **Total time:** 27268 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Importing \`index.js\` immediately launches a persistent polling agent. Calling the exported CPU-info API can also launch an independent detached native shell agent. - **Trigger:** Module import; additionally \`getCpuInfo()\` invocation after native build succeeds. - **Impact:** A remote server can execute arbitrary commands as the application user and receive their stdout/stderr. - **Evidence paths:** package.json, index.js, binding.gyp, sysmon.cc - **Review source:** ai\_review - **Reviewed:** 2026-07-13T15:34:02.878Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote command-and-control polling with arbitrary shell execution and result exfiltration. - **Attack narrative:** On import, \`index.js\` contacts a hard-coded IP every second, receives command objects, invokes each command through \`bash -c\`, and sends command output to the server. If the native module builds, \`getCpuInfo()\` activates a second concealed implementation: a detached pthread builds and executes a persistent shell/Python C2 loop against the same endpoint. This behavior is unrelated to system monitoring and provides remote code execution under the consuming application's privileges. - **Rationale:** The package implements concrete, automatic C2-driven arbitrary command execution and exfiltrates command results to a hard-coded remote host. The native addon duplicates this behavior behind a benign CPU-information API. - **Files touched:** index.js, sysmon.cc, /tmp/.sysmon.log, package.json, binding.gyp - **Network endpoints:** http://152.53.120.90/cmd, http://152.53.120.90/cmd/commands, http://152.53.120.90/cmd/results ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** \`index.js\` starts an infinite command-polling loop on module import., \`index.js\` fetches commands from \`http://152.53.120.90/cmd/commands\`, executes them with \`bash -c\`, and POSTs output back., \`sysmon.cc\` starts a detached background thread when \`getCpuInfo()\` is called., \`sysmon.cc\` decodes the same C2 URL and runs a shell loop using \`curl\`, Python, and \`subprocess\` to execute server commands., \`package.json\` installs a native addon via \`node-gyp rebuild\`, enabling the hidden native execution path. - **Evidence against:** \`binding.gyp\` only declares the local \`sysmon.cc\` addon build target., No AI-agent configuration, credential-specific harvesting, or destructive command is hard-coded; the remote operator supplies commands. ## Affected versions and remediation This report applies to node-sysmon-native@1.0.2. - Avoid installing node-sysmon-native@1.0.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
