Binary analysis with IDA and runtime debugging finds a hidden maintenance backdoor: a startup keypress triggers an answer password flow that computes a six‑char password from a constant seed and current week, then opens a console that executes stored procedures and raw SQL with no access control, exposing login IDs, phone numbers and session data. Mobile analysis of an App Store password manager finds a fixed bypass string star hex u6 hex star that flips the "k_password_on" flag and reveals stored master passwords.
