Beyond the Proxy: How KnoxSpy Cracks MDM and Certificate Pinning for Mobile App Sec

by ddos · March 20, 2026

KnoxSpy

KnoxSpy is developed by Appknox, a leading mobile security company dedicated to making mobile applications more secure through innovative security testing tools and platforms.

Traditional proxy tools like Burp Suite fail when dealing with:

Mobile Device Management (MDM) applications
Certificate pinning implementations
Custom security protocols
TLS/SSL bypass restrictions
Devices using VPN connections

KnoxSpy solves this by hooking directly into popular network libraries at runtime, even when the API traffic is routed through a VPN.
