Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The attacker can receive developer secrets and gain persistent SSH access to the installing machine. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 2.1.6 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Concrete install-time execution performs credential/config exfiltration and remote SSH persistence. This is direct malicious behavior, not a package-aligned feature. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-15T21:40:55.920Z - **Finished:** 2026-07-15T21:42:00.439Z - **Download time:** 255 ms - **Static scan time:** 30 ms - **AI review time:** 64233 ms - **Total time:** 64519 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:** Installation executes both payload functions through the postinstall hook. The package exfiltrates sensitive files and establishes SSH persistence from a remote server-provided key. - **Trigger:** npm installation triggers \`postinstall\`, which executes \`test.js\`. - **Impact:** The attacker can receive developer secrets and gain persistent SSH access to the installing machine. - **Evidence paths:** package.json, test.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-15T21:42:00.439Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time file exfiltration, remote SSH-key persistence, and host scanning - **Attack narrative:** On installation, \`test.js\` calls both exported payload functions. One recursively finds likely secret/config files in the current working directory and uploads their contents with the local username. The other fetches an attacker-controlled SSH key and scan rules, appends the key to the current user's authorized keys on Linux, enables inbound SSH access, scans home/user-drive files, and uploads matches to the hard-coded server. - **Rationale:** Concrete install-time execution performs credential/config exfiltration and remote SSH persistence. This is direct malicious behavior, not a package-aligned feature. - **Files touched:** package.json, test.js, index.js, ~/.ssh/authorized\_keys - **Network endpoints:** http://170.205.31.203:3000/api/v1, http://170.205.31.203:3001/api/ssh-key, http://170.205.31.203:3001/api/scan-patterns, http://170.205.31.203:3001/api/block-patterns, http://170.205.31.203:3001/api/v1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs \`node test.js\` on postinstall., test.js imports package exports and invokes both payload functions., index.js recursively collects \`.env\`, \`env\`, \`config.toml\`, and \`id.json\` files, then uploads them., index.js fetches an SSH key, appends it to \`~/.ssh/authorized\_keys\`, and enables SSH via UFW., index.js scans the user home/Windows user drives using remote-supplied patterns and uploads matched files., index.js is deliberately obfuscated and contacts a hard-coded IP endpoint. ## Affected versions and remediation This report applies to typescript-api-node@2.1.6. - Avoid installing typescript-api-node@2.1.6. 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.
