Symbolic execution tools
WebSymbolic Execution (description taken from "Symbolic execution for software testing: three decades later" ©ACM by Cristian Cadar and Koushik Sen, CACM 2013): Symbolic execution has garnered a lot of attention in recent years as an effective technique for generating high-coverage test suites and for finding deep errors in complex software applications. WebSep 30, 2024 · The use of symbolic execution brings a new tool to the fight against obfuscated macros that perform checks against the environment in order to evade analysis. This Excel 4.0 sample will de-obfuscate correctly only if the host has the correct environment. A possible set of correct environment values is:

Symbolic execution tools based on virtual machines solve the environment problem by forking the entire VM state. For example, in S2E [9] each state is an independent VM snapshot that can be executed separately. See more In computer science, symbolic execution (also symbolic evaluation or symbex) is a means of analyzing a program to determine what inputs cause each part of a program to execute.

WebUnlike most other symbolic execution tools, S2E performs in vivo analysis through the use of virtualization and dynamic translation of x86/ARM instructions. S2E ameliorates the path explosion problem by interleaving concrete/symbolic execution at different parts of the stack ( selective symbolic execution ) and allowing users to relax the consistency models … WebAccount Manager - Symbols & RTM.
