Common Mobile Vulnerabilities
OWASP Top 10 M1: Improper Platform Usage M2: Insecure Data
Storage M3: Insecure Communication M4: Insecure Authentication M5: Insufficient Cryptography M6: Insecure Authorization M7: Client Code Quality M8: Code Tampering M9: Reverse Engineering M10: Extraneous Functionality
Unauthorized access and fraud; Intelectual property theft; Trust damaged; Negative
end-user experiences; Negative, potentially permanent impact on the brand’s reputation; Ongoing financial losses; Privacy related and confidencial/sensitive data theft. Business Impact
How do I know if I'm vulnerable?
Can someone code-decrypt your app?
Can someone reverse engineer this app with automated tools?
How to Secure Mobile Devices
Source Code Encryption Penetration Tests Secure the Data-in-transit Database Encryption
Cryptography 1. 2. 3. 4. 5.
6. High-level Authentication 7. Secure the Backend 8. Minimize Storage
of Sensitive Data 9. Be careful with Third-Party Services
GENERAL REMOTE ATTESTATION INTEGRITY CHECKS ROOT DETECTION DEVICE BINDING SSL
PINNING EMULATOR DETECTOR RESOURCES ENCRYPTION INTEGRITY CHECKS ANTI-TEMPERING APPLICATION CODE ENCRYPTION CODE OBFUSCATION ANTI-HOOK ANTI-TEMPERING CODE
