Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The published postinstall clearly fetches and runs a first-party remote installer, which is unresolved install-time remote execution rather than a complete malware chain. Domain, global-only guards, and unobfuscated CLI structure make a publish block too likely to be a false positive. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-16T19:11:55.785Z - **Finished:** 2026-09-16T19:14:13.058Z - **Download time:** 505 ms - **Static scan time:** 13 ms - **AI review time:** 136755 ms - **Total time:** 137273 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 install runs a postinstall hook that downloads https://swirls.ai/install and executes it with bash, then may replace the package CLI with ~/.local/bin/swirls. The remote installer is not in this package, so its live payload cannot be verified from published source. Behavior matches a first-party native CLI bootstrap, not a proven malware chain. - **Trigger:** npm or bun global install of @swirls/cli (skipped for local installs, CI, and Windows). - **Impact:** The installing user runs whatever swirls.ai/install returns, and a native binary may overwrite bin/swirls and land in ~/.local/bin/swirls. - **Evidence paths:** package.json, scripts/install.js, bin/swirls - **Review source:** ai\_review - **Reviewed:** 2026-09-16T19:14:13.058Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time curl piped to bash, then binary copy - **Rationale:** The published postinstall clearly fetches and runs a first-party remote installer, which is unresolved install-time remote execution rather than a complete malware chain. Domain, global-only guards, and unobfuscated CLI structure make a publish block too likely to be a false positive. - **Files touched:** scripts/install.js, bin/swirls, ~/.local/bin/swirls - **Network endpoints:** https://swirls.ai/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** postinstall runs node scripts/install.js on install., Global installs pipe https://swirls.ai/install into bash through child\_process execSync., After the remote script, the installer copies ~/.local/bin/swirls over the package bin/swirls binary., The shipped bin/swirls placeholder tells users to drop --ignore-scripts or run the same curl-to-bash installer. - **Evidence against:** swirls.ai matches the scoped package name, author URL, and documented CLI product., The hook exits immediately unless the install is global npm or bun; CI and Windows are skipped., Published source is short and unobfuscated, with no secret harvesting, eval, agent-config writes, or runtime self-dependency., Scanner malware-fingerprint labels are not backed by extra hidden payload in this tarball. ## Affected versions and remediation This report applies to @swirls/cli@0.1.136. - Review the evidence and your use of @swirls/cli@0.1.136 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
