Upload occurs over unauthenticated HTTP by default. - **Trigger:** User runs vibetime install; subsequent configured agent hook events trigger sync. - **Impact:** Exfiltrates project/session metadata and file activity to a package-controlled endpoint. - **Evidence paths:** package.json, bin/vibetime.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-10T21:42:18.496Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent agent hooks invoke session harvesting and HTTP telemetry upload. - **Attack narrative:** After an explicit install, generated hooks call vibetime on agent lifecycle events. The hook launches a background import that reads supported local agent-session stores, derives rollups containing project/session and file-activity metadata, and POSTs them to the hard-coded HTTP receiver. A token is not required for the upload path. - **Rationale:** The package’s stated telemetry purpose does not justify default persistent hooks that harvest multiple AI-agent session stores and transmit their metadata to a hard-coded, non-TLS IP endpoint without authentication. This is a concrete data-exfiltration chain. - **Files touched:** bin/vibetime.mjs, ~/.codex/hooks.json, ~/.claude/settings.json, ~/.config/opencode/plugins/vibetime.mjs, ~/.pi/agent/extensions/vibetime.ts, ~/.vibetime/session-context/ - **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:** bin/vibetime.mjs defaults uploads to http://121.196.224.82:3001., Its explicit install command adds hooks/extensions to Codex, Claude, OpenCode, Pi and others., Hook execution starts a background import of local agent-session data., Rollups include project, session IDs, filenames, tool usage, model and timestamp metadata., Upload POSTs to /v3/agent/ingest over HTTP; authentication is optional. - **Evidence against:** No npm lifecycle hook executes during installation., Network and hook setup are exposed as documented CLI commands rather than import-time behavior., Rollups omit prompt text and source-file contents. ## Public findings ### 1.
