  • Family: Octo

    Octo is a banking malware with remote access capabilities first seen in April 2022.

  • Accessibility-driven UI automation to self-grant permissions

    Locates nodes in the Settings or package-installer user interface by text or view identifier and dispatches synthetic clicks. This lets the application approve its own permission dialogs, complete side-loading, and intercept attempts to reach the uninstall screen without any real user consent.

  • Android banker: accessibility service abuse with overlay injection

    DEX references AccessibilityService event hooks together with window-overlay creation and credential-capture primitives. This combination is the canonical Android banking-trojan pattern: the app reads screen content and injects fake login windows over legitimate banking apps.

  • Encrypted or packed staged payload inside Android package

    Extracted asset shows near-random entropy without a recognised container header, indicating an encrypted secondary payload staged for runtime decryption and loading. Correlate with any runtime class-loading detection on the same sample.

  • Notification listener abuse for OTP and message theft

    Binds a notification listener service and reads posted notification content, optionally dismissing notifications afterwards to hide them. This harvests one-time passcodes and private messages without ever requesting SMS permissions, which is why it has largely replaced SMS interception in modern ban

  • Silent screen capture via MediaProjection

    Acquires a MediaProjection session and pipes the virtual display into an image reader or encoder, enabling continuous capture of everything shown on screen including credentials and one-time codes. Combined with accessibility auto-approval this runs without further user interaction.

  • Loads dropped Dex/Jar

    Runs executable file dropped to the device during analysis.

    evasion

  • Makes use of the framework's Accessibility service

    Retrieves information displayed on the phone screen using AccessibilityService.

    collectiondefense_evasioncredential_access

  • Queries a list of all the installed applications on the device (Might be used in an attempt to overlay legitimate apps)

    bankerdiscovery

  • Queries the phone number (MSISDN for GSM devices)

    discovery

  • Acquires the wake lock

  • Makes use of the framework's foreground persistence service

    Application may abuse the framework's foreground service to continue running in the foreground.

    defense_evasionpersistence

  • Performs UI accessibility actions on behalf of the user

    Application may abuse the accessibility service to prevent their removal.

    evasion

  • Queries the mobile country code (MCC)

    discovery

  • Reads information about phone network operator.

    discovery

  • Requests accessing notifications (often used to intercept notifications before users become aware).

    collectioncredential_access

  • Requests disabling of battery optimizations (often used to enable hiding in the background).

    defense_evasion

  • Requests modifying system settings.
