Top Mobile Finance Apps Consistently Failing Security and Data Privacy Tests

**Executive Summary:** Zimperium scanned 300 top US mobile banking and payment apps (150 iOS, 150 Android) and found pervasive failures to follow OWASP Mobile Top 10 best practices, broad susceptibility to reverse engineering, insecure communication and storage practices, and extensive privacy risks (high rates of logging, pasteboard monitoring, ad frameworks collecting PII, weak TLS checks, exported components, etc.); the report quantifies affected apps per issue and recommends app shielding, code obfuscation, and runtime self-protection (zScan/zShield/zDefend) to reduce fraud and data leakage.
