It also registers a persistent local dashboard without an explicit user command. - **Trigger:** npm postinstall during global installation - **Impact:** It can alter AI-agent instructions and install a process that starts at login. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/prumo.mjs, lib/install.mjs, lib/autostart.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-19T11:16:13.594Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic agent configuration injection and dashboard persistence - **Attack narrative:** The postinstall hook checks whether the package is globally installed, then launches its own install --all command. That command detects supported AI-agent environments and writes the package skill plus Codex instruction content into their configuration locations. After successful installs it enables a platform-specific dashboard service, including launchd or systemd registration. These mutations occur during installation rather than after an explicit setup command. - **Rationale:** This is an unconsented postinstall chain that mutates broad AI-agent control surfaces and establishes login persistence. The absence of outbound exfiltration does not neutralize the concrete install-time control-surface behavior. - **Files touched:** ~/.agents/skills/prumo, ${CODEX\_HOME}/AGENTS.md, ${CODEX\_HOME}/AGENTS.override.md, ~/Library/LaunchAgents/dev.prumo.dashboard.plist, ~/.config/systemd/user/prumo-dashboard.service ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs a postinstall lifecycle script., When installed globally, that script automatically starts the package CLI with install --all., The CLI treats that invocation as a lifecycle install and applies installation plans to every detected agent harness., The installer copies its skill payload into global and project agent skill directories and modifies Codex instruction files., The same automatic install enables a login-persistent dashboard through platform schedulers. - **Evidence against:** The inspected network behavior is limited to a loopback dashboard; no credential collection or outbound exfiltration sink was found. ## Affected versions and remediation This report applies to @henri-ralmeida/prumo@1.3.14. - Avoid installing @henri-ralmeida/prumo@1.3.14. 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.
