- Family: Octo
Octo is a banking malware with remote access capabilities first seen in April 2022.
- Octo payload 1 IoCs
resource yara_rule behavioral1/files/fstream-1.dat family_octo - Accessibility-driven UI automation to self-grant permissions 1 IoCs
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.
resource yara_rule behavioral1/files/fstream-1.dat ANDROID_Accessibility_AutoClick_SelfGrant - Android banker: accessibility service abuse with overlay injection 1 IoCs
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.
resource yara_rule behavioral1/files/fstream-1.dat ANDROID_Overlay_Banker_AccessibilityAbuse - Notification listener abuse for OTP and message theft 1 IoCs
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
resource yara_rule behavioral1/files/fstream-1.dat ANDROID_NotificationListener_OTP_Theft - Scripted prompt coaching the user to enable Accessibility 1 IoCs
Contains step-by-step instructional text walking the victim through enabling an accessibility service. Because Android deliberately makes this flow difficult, malware ships explicit coaching copy; the presence of such a script alongside an accessibility service is a strong abuse indicator.
resource yara_rule behavioral1/files/fstream-1.dat ANDROID_Accessibility_SocialEngineering_Prompt - Silent screen capture via MediaProjection 1 IoCs
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.
resource yara_rule behavioral1/files/fstream-1.dat ANDROID_MediaProjection_ScreenCapture - Loads dropped Dex/Jar 1 TTPs 2 IoCs
Runs executable file dropped to the device during analysis.
