It changes foreign agent control surfaces and creates a process that starts at login without an explicit setup command. - **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:** 1.3.16 - **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. A global installation automatically detects AI-agent environments and writes Prumo instructions into their configuration. It then registers a persistent local dashboard process. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-19T11:14:50.305Z - **Finished:** 2026-09-19T11:15:49.952Z - **Download time:** 755 ms - **Static scan time:** 478 ms - **AI review time:** 58413 ms - **Total time:** 59647 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:** A global installation automatically detects AI-agent environments and writes Prumo instructions into their configuration. It then registers a persistent local dashboard process. - **Trigger:** npm postinstall during a global installation of the package. - **Impact:** It changes foreign agent control surfaces and creates a process that starts at login without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/prumo.mjs, lib/install.mjs, lib/autostart.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-19T11:15:49.952Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic AI-agent configuration mutation and dashboard autostart registration. - **Attack narrative:** During global npm installation, postinstall runs \`prumo install --all\`. That flow discovers supported agent harnesses, injects Prumo instructions into Codex configuration, and automatically enables a persistent dashboard service. The changes affect user-controlled agent configuration and operating-system startup settings without requiring the user to run the documented install command or select a target. - **Rationale:** The package performs unconsented postinstall mutation of broad AI-agent control surfaces and establishes persistence. This meets the install-control-surface blocking rule even though the observed dashboard binds only to loopback. - **Files touched:** AGENTS.override.md, AGENTS.md, Library/LaunchAgents/dev.prumo.dashboard.plist, .config/systemd/user/prumo-dashboard.service - **Network endpoints:** http://127.0.0.1:4949 ### 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 a postinstall lifecycle script., Postinstall automatically invokes the CLI with install --all when globally installed., The installer appends package instructions to Codex AGENTS files without an explicit user command., The automatic install enables a dashboard after any successful harness installation., The dashboard creates persistent launchd, systemd, or startup entries. - **Evidence against:** No remote network endpoint, credential collection, or data-exfiltration sink was found in the inspected install path. ## Affected versions and remediation This report applies to @henri-ralmeida/prumo@1.3.16. - Avoid installing @henri-ralmeida/prumo@1.3.16. 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.
