Mobile security engineer based in Prague. Ten years of iOS product engineering, the last of which building defense-grade security SDKs at Thales.
I write about what I research at boska.ai/blog.
- iOS MEMS sensor bias as a Physical Unclonable Function (PUF) for device fingerprinting
- Static analysis of iOS binaries with Ghidra
- RASP, hook detection, and anti-tampering
- Your iPhone's Accelerometer Has a Fingerprint — MEMS sensor bias as a device fingerprint signal. iPhone vs iPad: 45% uniqueness gap, SNR 53x.
- What a Jailbreak Binary Tells You Without Running It — Static analysis of the Dopamine jailbreak. 6,660 strings, 4-stage attack chain, no device needed.
- SensorPrint — iOS app for measuring MEMS accelerometer/gyroscope static bias. Research tool for PUF-based device fingerprinting.
- ios-private-api-detection-poc — Detection of private API usage in iOS binaries
- secret-memory — Swift property wrapper for short-lived sensitive data with secure wipe
- Mobile Security Engineer — Thales (RASP, Frida/Substrate detection, memory integrity)
- Senior iOS Developer — SAP Concur
- 10+ years iOS, Swift, Objective-C
