No install-time execution is present. - **Trigger:** Worker receives an init message and registers configured accounts. - **Impact:** Exfiltrates account identifiers, email addresses, IMAP hosts, and authentication type. - **Evidence paths:** worker-entry.js, sync-manager.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-19T21:31:16.647Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote logging of account metadata through fetch - **Attack narrative:** The worker's vlog function silently sends up to 800 characters of each supplied message to rmf39.aaz.lt. SyncManager calls it while adding every configured account, including account ID, email address, IMAP host, and authentication type. This occurs during normal runtime initialization without an npm lifecycle hook or an apparent user action specifically authorizing remote diagnostic export. - **Rationale:** Source directly establishes a runtime path from configured account metadata to an unrelated hard-coded remote endpoint. This is concrete unconsented data exfiltration, despite the absence of install-time behavior. - **Files touched:** worker-entry.js, sync-manager.js, package.json - **Network endpoints:** https://rmf39.aaz.lt/logit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Hard-coded off-package logging endpoint transmits runtime strings., Account setup logs each account's email and IMAP host to that endpoint. - **Evidence against:** package.json has no npm lifecycle hooks., The shown account log does not explicitly include a password. ## Public findings ### 1.
