  • Android dropper: runtime DEX/class loading of a staged payload 1 IoCs

    Sample resolves and loads executable code at runtime via DexClassLoader/InMemoryDexClassLoader combined with reflection and asset or network payload retrieval. Legitimate apps rarely need in-memory DEX loading; this is the standard staging mechanism for Android droppers evading store review.

  • Boot-triggered restart with disguised foreground service 1 IoCs

    Restarts itself on device boot and holds a foreground service with a low-visibility notification channel, keeping the process alive across reboots and outside normal background limits. Malicious use is distinguished by pairing this with surveillance or remote-control primitives.

  • 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

  • Declares broadcast receivers with permission to handle system events 1 IoCs
  • Declares services with permission to bind to the system 4 IoCs
  • Requests dangerous framework permissions 8 IoCs
  • Untrusted Codesign Signers 1 IoCs
