It activates during account setup after a consumer calls the exported Android initializer. - **Trigger:** Calling initAndroid() with cloud account configuration available. - **Impact:** A third-party host can receive account identifiers, mail server details, usernames, and IMAP passwords. - **Evidence paths:** android-bootstrap.ts, web-settings.ts, package.json, index.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-28T04:37:00.020Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Credential-bearing configuration is serialized into a remote log URL. - **Attack narrative:** The Android initializer loads cloud accounts, then serializes each account's IMAP configuration into a verbose log message. That logger silently sends up to 800 characters to rmf39.aaz.lt. Account normalization includes the IMAP password in this object, making credential exfiltration concrete when password-authenticated accounts are configured. This is runtime behavior rather than an npm lifecycle action. - **Rationale:** The source contains a direct chain from stored account password to an unrelated remote logging endpoint during normal Android initialization. Absence of lifecycle hooks does not mitigate this credential exfiltration path. - **Files touched:** package.json, index.ts, android-bootstrap.ts, web-settings.ts, worker-entry.ts, sync-manager.ts, main-thread-host.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:** Android bootstrap silently sends verbose log text to an unrelated remote host., The bootstrap serializes each account's IMAP configuration into that remote log., Account normalization places the account password in the serialized IMAP configuration., The credential-bearing log runs while Android account setup processes cloud accounts. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The main entry only exports library APIs and does not start the Android bootstrap on import. ## Public findings ### 1.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** android-bootstrap.ts - **Public source:** [View source]() Android bootstrap silently sends verbose log text to an unrelated remote host.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** web-settings.ts - **Public source:** [View source]() Account normalization places the account password in the serialized IMAP configuration. Public source snippet (untrusted): ```typescript imap: { host: acct.imap?.host || provider?.imap.host || `imap.${domain}`, port: acct.imap?.port || provider?.imap.port || 993, tls: acct.imap?.tls ?? provider?.imap.tls ?? true, auth: acct.imap?.auth || provider?.imap.auth || "password", user: acct.imap?.user || user, password: acct.imap?.password || acct.password, }, ``` ### 9.
