octo banker collection credential_access discovery evasion impact infostealer persistence rat stealth trojan
- Octo
  Octo is a banking malware with remote access capabilities first seen in April 2022.
  banker trojan infostealer rat octo
- Octo payload
- Makes use of the framework's Accessibility service
  Retrieves information displayed on the phone screen using AccessibilityService.
  collection evasion credential_access
- Prevents application removal
  Application may abuse the framework's APIs to prevent removal.
  evasion
- Queries a list of all the installed applications on the device (Might be used in an attempt to overlay legitimate apps)
  banker discovery
- Removes its main activity from the application launcher
  stealth trojan evasion
- Requests accessing notifications (often used to intercept notifications before users become aware).
  collection credential_access
- Requests modifying system settings.
  evasion
- Checks CPU information
  Checks CPU information which indicate if the system is an emulator.
  evasion discovery
- Checks memory information
  Checks memory information which indicate if the system is an emulator.
  evasion discovery
- Loads dropped Dex/Jar
  Runs executable file dropped to the device during analysis.
  evasion
- Makes use of the framework's foreground persistence service
  Application may abuse the framework's foreground service to continue running in the foreground.
  evasion persistence
- Obtains sensitive information copied to the device clipboard
  Application may abuse the framework's APIs to obtain sensitive information copied to the device clipboard.
  collection credential_access impact
- Queries the mobile country code (MCC)
  discovery
- Queries the phone number (MSISDN for GSM devices)
  discovery
- Registers a broadcast receiver at runtime (usually for listening for system events)
  persistence
- Acquires the wake lock
- Queries the unique device ID (IMEI, MEID, IMSI)
  discovery
- Reads information about phone network operator.
  discovery
- Requests disabling of battery optimizations (often used to enable hiding in the background).
