This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 89.0% - **Started:** 2026-08-13T12:01:44.340Z - **Finished:** 2026-08-13T12:04:02.712Z - **Download time:** 761 ms - **Static scan time:** 646 ms - **AI review time:** 136964 ms - **Total time:** 138372 ms ## Security analysis ### Published attack-surface review - **Summary:** Uninstall-time code terminates its own marked processes and removes its marked Claude hooks. No install-time foreign-agent configuration or exfiltration was confirmed. - **Trigger:** Global npm uninstall from a node\_modules installation. - **Impact:** May alter ~/.claude/settings.json and stop matching package services during removal. - **Evidence paths:** package.json, node/bin/postinstall.js, node/bin/preuninstall.js, node/bin/install.js, deploy/ack\_watchdog.js, node/enforcer/agent\_enforcer\_daemon.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T12:04:02.712Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Uninstall cleanup of package processes and Claude hook entries. - **Rationale:** Source inspection found no concrete malware chain, network exfiltration, or unconsented install-time agent-control mutation. Per policy, the uninstall-only Claude configuration mutation warrants a warning. - **Files touched:** ~/.claude/settings.json, /tmp/ack-preuninstall.log ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Global preuninstall lifecycle runs on package removal., It terminates matching package daemon, monitor, and watchdog processes., It rewrites Claude settings to remove ack.js-marked hooks. - **Evidence against:** Postinstall only logs setup guidance and states it performs no configuration., Claude hook wiring is performed by explicit \`ack configure\` and can be declined., No exfiltration, remote payload loading, or covert install-time configuration was found in inspected sources. ## Public findings ### 1.

Public source snippet (untrusted): ```javascript L264: L265: // MOD-007: `spawn()` not throwing means the OS accepted the fork request, L266: // not that the process is still running or responding to RPC a moment ... L268: // through EnforcerClient (client.js), since that reads its token from L269: // process.env.ACK_AUTH_TOKEN globally, and mutating the installer's own L270: // process-wide env for a single liveness check is worse than a small ...
