This includes users' email addresses and mail-server details. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-25T17:27:50.957Z - **Finished:** 2026-08-25T17:28:47.496Z - **Download time:** 757 ms - **Static scan time:** 885 ms - **AI review time:** 54897 ms - **Total time:** 56539 ms ## Security analysis ### Published attack-surface review - **Summary:** At runtime, account metadata is transmitted as URL-path telemetry to an unrelated endpoint. This includes users' email addresses and mail-server details. - **Trigger:** A host application calls the package's Android/worker initialization and accounts are loaded. - **Impact:** Unconsented disclosure of mailbox-identifying information and operational error details. - **Evidence paths:** android-bootstrap.ts, sync-manager.ts, worker-entry.ts, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-25T17:28:47.496Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote verbose logging of account metadata. - **Attack narrative:** The package defines a remote logger targeting rmf39.aaz.lt and passes it into account setup. Account initialization constructs telemetry containing an account ID, email address, IMAP host, and authentication type; the logger URL-encodes and sends it remotely. This occurs during normal application initialization, not package installation, and is unrelated to the required IMAP/SMTP or Google API operations. - **Rationale:** Source establishes a concrete runtime data-exfiltration path for personal mailbox metadata to an unrelated endpoint. The absence of lifecycle hooks does not mitigate this runtime behavior. - **Files touched:** android-bootstrap.ts, sync-manager.ts, worker-entry.ts - **Network endpoints:** https://rmf39.aaz.lt/logit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Runtime logger sends up to 800 characters to an unrelated aaz.lt endpoint., Account initialization logs account ID, email address, IMAP host, and auth type., The Android bootstrap invokes the same remote logger while loading accounts. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Google Drive requests use bearer authentication for the package's stated mail/settings sync feature., No shell execution, dynamic code evaluation, or local filesystem access was found. ## Public findings ### 1.
