Tracing Struct Accesses with Struct Stalker presented at ReconMontreal2018 2018

by Jeff Dileo,

Summary : Struct Stalker is an LLDB script that instruments processes to trace struct/object accesses in C/C++ applications. It recursively walks through all fields in a targeted variable variable to make each each one inaccessible through page permissions, and catches and processes all ensuing page faults to track memory accesses. This talk will cover the Struct Stalker tool and will additionally include a brief introduction to LLDB scripting that covers a bunch of useful stuff that the LLDB "documentation" does not.
