R2Pay Under the Microscope: Breaking White-Box Crypto
Discover how we broke the R2Pay white-box AES implementation from scratch — recovering the PIN code through fuzzing, identifying PBKDF2-HMAC-SHA256 key derivation from memory traces, and extracting the AES master key r2p4y1sN0wSecur3 using Differential Computation Analysis with Frida and QBDI. No source code. No symbols. Just memory.
