M-10 discusses the lack of binary protection in mobile applications. It can allow attackers to reverse engineer apps to steal intellectual property, inject malicious code, or bypass security controls. Detection involves checking if an app's binary can be reversed or modified using tools like dex2jar or Clutch. This can lead to piracy, data theft, unauthorized access, and revenue loss. Prevention involves implementing controls like root detection, checksums, and certificate pinning, while also protecting that code from reverse engineering and modification.
