Solution Detail Proven and trusted by globally famous banks and game publishers from 10 years ago, CrackProof protects Apps against various risks like tampering, pirating, reverse-engineering, and more. For example, Android Apps (APK file) is easily unpackaged and DEX codes inside can be decompiled to source codes, which allows a malicious person to modify the original Java codes or add other codes to create a fake App. If the fake App is distributed via a third part Market, it might bring unpredictable damages to people, as the fake App might steal personal information from the mobile phone, force the user to connect dangerous website and finally let the user download malware. Without countermeasures against unauthorized analysis and tampering, publicized Apps can pose a number of risks to both app providers and users, since the Apps might become a prey to malicious people. CrackProof is also available for iOS and Windows.
The following are the possible risks in case that non-protected App were spread:

Risks for app providers

  • Leak of confidential information, leading to attacks targeting business systems
  • Monetary loss through circulation of pirated apps
  • Reputational damage through circulation of fake apps

Risks for app users
  • Leak of private data like address book contacts, photos, etc.
  • Leak of activity or location data via control of microphone, camera, GPS, etc.
  • Monetary loss due to fraudulent Internet banking transactions.
