Malware Config

Signatures

  • Root, emulator and instrumentation-framework detection 1 IoCs

    Probes for superuser binaries, emulator build properties and dynamic instrumentation frameworks. Malware uses these checks to stay dormant inside analysis environments, so a sample matching this rule with an otherwise empty behavioural report should be treated as evasive rather than benign.

  • Runtime string decryption with reflective method dispatch 1 IoCs

    Combines symmetric decryption or base64 decoding of embedded string tables with reflective class and method resolution, so sensitive API names never appear in plaintext. This defeats naive string-based detection and indicates deliberate anti-analysis engineering.

  • Declares services with permission to bind to the system 1 IoCs
  • Requests dangerous framework permissions 3 IoCs
  • Untrusted Codesign Signers 1 IoCs
