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. Running the CLI install command writes agent hooks that invoke this package for prompt, permission, and tool events. The hooks trigger background collection of local agent history and upload it, with a persisted bearer token, to a fixed HTTP IP address. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-13T03:00:28.117Z - **Finished:** 2026-09-13T03:01:27.228Z - **Download time:** 255 ms - **Static scan time:** 1541 ms - **AI review time:** 57314 ms - **Total time:** 59111 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:** Running the CLI install command writes agent hooks that invoke this package for prompt, permission, and tool events. The hooks trigger background collection of local agent history and upload it, with a persisted bearer token, to a fixed HTTP IP address. - **Trigger:** The user runs vibetime install, then an installed AI-agent hook fires. - **Impact:** Agent activity and the configured bearer token can be disclosed to the operator of the fixed endpoint. - **Evidence paths:** package.json, bin/vibetime.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-13T03:01:27.228Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent AI-agent hooks collect activity and send authenticated rollups to a hard-coded remote service. - **Attack narrative:** The CLI has no automatic npm lifecycle trigger, but its explicit install command modifies AI-agent hook configuration. Those hooks run vibetime when prompts, permissions, and tool events occur, start a background history import, and upload rollups using a saved bearer token. The remote defaults to an unauthenticated HTTP IP address rather than the advertised service domain, making this a concrete credential and activity-exfiltration path. - **Rationale:** Source establishes an explicit-command persistence chain from broad AI-agent hooks to authenticated uploads at a hard-coded HTTP IP endpoint. The lack of an install lifecycle hook reduces automatic-install risk but does not remove the concrete exfiltration capability. - **Files touched:** ~/.codex/hooks.json, ~/.vibetime/config.json, ~/.vibetime/machine-id, ~/.vibetime/backfill-state.json, ~/.vibetime/sync-local-trigger.json - **Network endpoints:** http://121.196.224.82:3001/v3/agent/ingest ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The default service is a hard-coded HTTP endpoint at an unrelated IP address., The explicit install command adds hooks for prompt, permission, and tool events to the user's Codex configuration., Hook activation starts a background import that collects local agent history and uploads rollups., Uploads include the saved bearer token and machine identity headers., The package has no npm install lifecycle hook; its integration is activated by its CLI install command. - **Evidence against:** The manifest exposes only a CLI and has no preinstall, install, or postinstall script., The hook installation path is an explicit user command rather than automatic package-install execution. ## Affected versions and remediation This report applies to @yhong91/vibetime@0.1.76. - Avoid installing @yhong91/vibetime@0.1.76. 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.
