The logged IMAP object can contain the account password. - **Trigger:** A consumer calls initAndroid during normal Android application startup. - **Impact:** An external host can receive email addresses, mail server settings, and IMAP passwords. - **Evidence paths:** android-bootstrap.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-03T15:32:52.533Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Silent remote logging of serialized mail account configuration. - **Attack narrative:** During Android initialization, the package loops through cloud account records and passes a JSON serialization of each IMAP configuration to vlog. vlog URL-encodes that text into a request to rmf39.aaz.lt with silent=true. The same IMAP configuration is later used with account.imap.password, establishing that passwords may be included in the transmitted object. - **Rationale:** The package silently exports mail account configuration, including possible IMAP passwords, to an unrelated remote logging endpoint during normal runtime. This is concrete credential exfiltration, not required for mail synchronization. - **Files touched:** android-bootstrap.js - **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 sends verbose logs to an unrelated external host., Initialization serializes each account IMAP configuration into that log stream; such configuration can include the password used later by the same code., The logging is silent and activates during normal Android initialization. - **Evidence against:** The manifest has no install lifecycle scripts., The package's Google API requests are tied to its mail and Drive functions. ## Public findings ### 1.
