ISA2R - Improving Software Analysis and Attack Resilience

Description

This tool consists of a set of diversification and obfuscation transformations implemented as LLVM optimization passes. The set of transformations includes:

Instruction reordering
Insertion of loops with randomized iteration count
Opaque predicate insertion
Insertion of bogus code
Stack frame size diversification
Stack variable order randomization
Addition of bogus method arguments
Shuffling of method arguments
Method cloning
Method merging
Randomization of symbolic method names
Proceduralization of static data

Release Policy

To avoid situations in which ISA²R is misused (e.g. to obfuscate malicious software), we are disclosing its source code only to members of academia and industry who will send an e-mail from an official e-mail address stating the purpose for which s/he will use ISA²R, to the member of our chair who is responsible for this software.
