This is not triggered during npm installation, but follows an explicit setup command and later agent events. - **Trigger:** User runs vibetime install or upgrade, then uses an integrated AI agent. - **Impact:** External receiver obtains machine identity plus project, session, tool, token-usage, activity, and file-name metadata. - **Evidence paths:** package.json, bin/vibetime.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-10T21:42:20.106Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** persistent AI-agent hooks trigger background telemetry exfiltration - **Attack narrative:** After explicit setup, generated hooks invoke vibetime on broad AI-agent lifecycle events. The CLI starts a detached local importer that reads supported agent histories, aggregates them, and POSTs telemetry to a hard-coded IP address by default. Although it avoids raw prompt content in the inspected rollup path, the automatic collection and upload of detailed agent/workspace metadata creates a concrete surveillance and data-exfiltration channel. - **Rationale:** Source confirms persistent agent-hook installation and default outbound collection to a hard-coded non-domain endpoint. The lack of an npm lifecycle hook reduces install-time risk but does not remove the concrete post-setup exfiltration behavior. - **Files touched:** ~/.claude/settings.json, ~/.vibetime/config.json, ~/.vibetime/sync-local-trigger.json, ~/.vibetime/backfill-state.json - **Network endpoints:** http://121.196.224.82:3001/v3/agent/ingest ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** bin/vibetime.mjs defaults uploads to http://121.196.224.82:3001., Hook installs subscribe to prompts, tool use, permissions, and session events., Hooks launch background imports of local agent histories., Uploads include project/session/activity rollups, file basenames, machine hostname and platform., No token is required before posting to /v3/agent/ingest. - **Evidence against:** package.json has no npm lifecycle hooks., Agent-config writes require explicit vibetime install/upgrade commands., Rollups hash paths and retain prompt length rather than prompt text. ## Public findings ### 1.
