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. On npm installation in a project that already has .claude, the package automatically deposits package-controlled hook and launcher files into that AI-agent control surface. In a Claude session it also writes a message intended for Claude to relay. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-07T21:03:48.212Z - **Finished:** 2026-09-07T21:05:09.388Z - **Download time:** 514 ms - **Static scan time:** 14202 ms - **AI review time:** 66457 ms - **Total time:** 81176 ms The recorded confidence comes from the underlying analysis.

In a Claude session it also writes a message intended for Claude to relay. - **Trigger:** npm postinstall while the consumer project contains .claude; the notice path additionally requires a Claude-session environment variable. - **Impact:** Package code can persist as project-level Claude scripts and helpers without an explicit setup command, influencing later agent sessions. - **Evidence paths:** package.json, scripts/post-install-bootstrap.mjs, bin/lib/shipped-scripts.json, scripts/post-install-notice.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-07T21:05:09.388Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic copying of package-selected agent scripts and helpers into the consumer project. - **Attack narrative:** Installing the package runs postinstall automatically. If the consumer already has a .claude directory, the bootstrap creates or overwrites project .claude scripts, libraries, migrations, and helpers from a package-controlled manifest, including hook and prompt-related components. In Claude environments it also leaves a restart message for the agent. This is an unconsented lifecycle mutation of a broad project AI-agent control surface; later Claude sessions may execute or rely on the deposited files. - **Rationale:** The install lifecycle performs broad project-level Claude control-surface mutation rather than limiting itself to package-owned files or an explicit setup command. No lifecycle exfiltration was found, but the automatic persistence is concrete and sufficient to block publication. - **Files touched:** .claude/scripts/\*\*, .claude/scripts/lib/\*\*, .claude/scripts/migrations/\*\*, .claude/helpers/\*\*, .moflo/restart-pending.json, .moflo/last-install-banner.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The automatic postinstall hook runs a bootstrap that modifies the consumer project., The bootstrap copies a package-selected set of scripts, every bin/lib file, migrations, and helpers into an existing .claude control surface., The copied manifest includes hook, prompt, session-start, and subagent-related files., A Claude-session postinstall writes restart instructions that are intended for Claude to relay. - **Evidence against:** No credential harvesting, secret exfiltration, or lifecycle network request was found in the inspected install scripts., The same-name dependency is only a development dependency, not a runtime self-dependency. ## Affected versions and remediation This report applies to moflo@4.13.2. - Avoid installing moflo@4.13.2. 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.
