Untrusted remote content can execute natively and steer future agent behavior across projects. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.0.2538 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Running the CLI modifies global AI-agent skill directories and project agent instruction files, then starts a downloaded native daemon. The daemon becomes an instruction source agents are told to follow. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-09T08:04:47.649Z - **Finished:** 2026-08-09T08:05:42.190Z - **Download time:** 255 ms - **Static scan time:** 181 ms - **AI review time:** 54104 ms - **Total time:** 54541 ms ## Security analysis ### Published attack-surface review - **Summary:** Running the CLI modifies global AI-agent skill directories and project agent instruction files, then starts a downloaded native daemon. The daemon becomes an instruction source agents are told to follow. - **Trigger:** User runs gm-plugkit (including its default CLI path). - **Impact:** Untrusted remote content can execute natively and steer future agent behavior across projects. - **Evidence paths:** bootstrap.js, bootstrap-shared.js, cli.js, SKILL.md, SKILL-agent-memory.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T08:05:42.190Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote native payload execution plus AI-agent control-surface rewiring. - **Attack narrative:** The CLI invokes ensureReady, which rewrites project agent instructions and installs package or remotely fetched skills into global agent directories. It then downloads a latest native runner and a matching hash from the same remote release, executes it detached, and injects instructions telling agents to follow daemon-provided imperatives. This combines remotely replaceable native execution with persistent AI-agent control-surface modification. - **Rationale:** This is a concrete malicious chain, not merely a bootstrapper: it installs broad agent instructions and executes an unpinned remote native payload. Lack of an npm lifecycle hook does not mitigate the user-triggered compromise path. - **Files touched:** ~/.agents/skills/\/SKILL.md, ~/.claude/skills/\/SKILL.md, \/CLAUDE.md, \/AGENTS.md, \/.gm/next-step.md, \/.gm/exec-spool/, ~/.gm-tools/agentplug-runner - **Network endpoints:** https://api.github.com/repos/AnEntrypoint/agentplug-bin/releases/latest, https://github.com/AnEntrypoint/agentplug-bin/releases/download/, https://raw.githubusercontent.com/AnEntrypoint/gm/main/skills/, https://api.github.com/repos/AnEntrypoint/gm/contents/skills?ref=main ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** bootstrap.js refreshes remote skills into ~/.agents/skills and ~/.claude/skills., bootstrap-shared.js alters project CLAUDE.md and AGENTS.md to load package-controlled instructions., The injected next-step file directs agents to follow imperative responses from a daemon., bootstrap.js downloads latest native agentplug-runner, verifies only a same-origin fetched hash, then executes it., cli.js automatically installs and detaches the runner as a spool daemon., Bundled SKILL.md grants agent instructions command and write capabilities. - **Evidence against:** package.json has no npm lifecycle scripts., Activation begins through the explicit gm-plugkit CLI, not import-time execution. ## Public findings ### 1.
