The diagnostic includes a JSON-serialized IMAP configuration that can contain the account password. - **Trigger:** A consumer calls initAndroid and cloud accounts are loaded. - **Impact:** IMAP credentials and account metadata can be exposed to rmf39.aaz.lt. - **Evidence paths:** package.json, android-bootstrap.ts, worker-entry.ts, sync-manager.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-28T01:22:05.245Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote logging of account configuration. - **Attack narrative:** When the Android bootstrap loads cloud accounts, it serializes each account's IMAP settings into a vlog message. vlog sends that text to rmf39.aaz.lt. The same source uses account.imap.password as the IMAP credential, so serializing the configuration can disclose the password without user consent. - **Rationale:** This is a concrete credential-exfiltration path to an unrelated logging endpoint during normal application initialization. No install hook is required for the harm to occur. - **Files touched:** android-bootstrap.ts - **Network endpoints:** rmf39.aaz.lt ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The Android bootstrap transmits vlog text to rmf39.aaz.lt., Account setup logs the full IMAP configuration, which includes a password field., Calling initAndroid starts the account-loading flow that reaches this logging. - **Evidence against:** package.json has no install lifecycle hook., The package otherwise implements browser mail storage and sync features. ## Public findings ### 1.
