Method hooks malloc/free/realloc via DLL injection and records allocation metadata, then logs accesses either with DBI or with a custom page-fault tracking system that marks pages non-present and single-steps to capture reads/writes. Uses a fixed-size slab allocator to limit faults, a small x86 emulator/JIT and guard-page optimizations to reach millions of accesses per minute. Reports about 200 recovered structures, ~6,000 variable types set in IDA/Hex-Rays and tens of thousands of applied offsets.
