Installation can silently alter available agent instructions and add executables obtained from redirected remote archives. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.3.1 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installing the package triggers a postinstall routine that writes an AI-agent skill into the user's broad ~/.agents skill directory. It also downloads and extracts native toolchain archives when dependencies are absent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-08T15:17:29.526Z - **Finished:** 2026-09-08T15:18:49.382Z - **Download time:** 253 ms - **Static scan time:** 703 ms - **AI review time:** 78899 ms - **Total time:** 79856 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:** Installing the package triggers a postinstall routine that writes an AI-agent skill into the user's broad ~/.agents skill directory. It also downloads and extracts native toolchain archives when dependencies are absent. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** Installation can silently alter available agent instructions and add executables obtained from redirected remote archives. - **Evidence paths:** package.json, dist/toolchain.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T15:18:49.382Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic AI-agent skill injection and remote native toolchain installation. - **Attack narrative:** A normal npm install invokes the postinstall script. That script initializes package state, selects ~/.agents/skills as the default agent skill root, and writes a wowdump skill without an explicit user command. If Java or Ghidra is missing on Windows, it follows redirects while downloading fixed GitHub archives, extracts them, and installs the resulting native toolchains under the user home. This combines automatic lifecycle execution with a broad AI-agent control-surface write and remote executable delivery. - **Rationale:** The package performs unconsented postinstall mutation of a foreign, broad AI-agent skill directory. Its automatic remote archive download and extraction increases the install-time supply-chain impact. - **Files touched:** dist/toolchain.js, ~/.agents/skills/wowdump/SKILL.md, ~/.agents/skills/wowdump/commands.md, ~/.wowdump/toolchains - **Network endpoints:** https://github.com/adoptium/temurin21-binaries/releases/download/jdk-21.0.8%2B9/OpenJDK21U-jdk\_x64\_windows\_hotspot\_21.0.8\_9.zip, https://github.com/NationalSecurityAgency/ghidra/releases/download/Ghidra\_11.3.2\_build/ghidra\_11.3.2\_PUBLIC\_20250415.zip ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs dist/toolchain.js automatically during postinstall., Postinstall defaults the agent skill directory to ~/.agents/skills and writes a wowdump SKILL.md there., When toolchains are missing, postinstall downloads redirected GitHub archives, extracts them, and installs their contents. - **Evidence against:** The download URLs are hard-coded GitHub release URLs and managed installation is limited to Windows., Skill files are created with exclusive writes, so existing files are preserved. ## Affected versions and remediation This report applies to wowdump@0.3.1. - Avoid installing wowdump@0.3.1. 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.
