Taint analysis and pattern matching with Pin; Concolic execution - Taint analysis with Valgrind and constraints path solver with Z3 . Triton is a dynamic binary analysis (DBA) framework. It’s generally best to limit the number of places and items that can impart taint, to reduce the bookkeeping load on players and the GM. Taint Analysis Taint analysis provides information about which registers and memory addresses are controllable by the user at each program point: – Assists the symbolic engine to setup the symbolic variables (a symbolic variable is a memory area that the user can control) – May assist the symbolic engine to perform some symbolic optimizations Bloomberg delivers business and markets news, data, analysis, and video to the world, featuring stories from Businessweek and Bloomberg News on everything pertaining to politics Practical Binary Analysis is the first book of its kind to present advanced binary analysis topics, such as binary instrumentation, dynamic taint analysis, and symbolic execution, in an accessible way. Triton also multiplexes these two features onto multiple implementations; one such implementation makes use of Intel Pin to execute the instructions on a real processor. With this method it is possible to check the registers and the memory areas which can be controlled by the user when a crash occurs - That can be useful. TAINTINDUCE can be used as a standalone taint engine or be used to complement existing taint engines for unhandled instructions.

In addition, TAINTINDUCE is useful as a cross-reference tool. This method will be voided if the obfuscator writes the junk value into the memory. For example, consider the task of conducting a whole-system dynamic taint analysis o Taint Analysis to discover what branch depends on what input o Symbolic Execution with constraint solver to build input to take that branch. Among those, we had to choose three.
