Contrary to most common disassemblers (e.g.

It reconstructs the control flow graph (CFG) of the code while disassembling and analyzing the binary. The static code analyzer together with the disassembler front-ends comprise a recursive descent disassembler. Currently GDSL comes with disassembler specifications for the Intel x86-32 and x86-64 and the AVR-8 architecture, thus replacing the hand written front-ends of the Bindead analyzer. GDSL compiles the instructions specification using one of the available language binding back-ends to a disassembler library that can be plugged into other projects. The projectĪllows to specify the syntax and semantics of machine instructions in a domain specific language that wasĭesigned for exactly this purpose. Hence, the Generic Decoder Specification Language Toolkit GDSL was started. Currently we have disassemblers for Intel x86-32 and x86-64 and for the AVR-8 architecture.Īs writing front-ends by hand proved to be tedious and error prone and after discussing the issue with people from the reverse engineering community the consensus was that there should be a simpler way to build and share descriptions for machine instructions.
We can thus use different disassembler front-ends for different architectures with the same code analyzer. To analyze the code we currently use a hand-written disassembler that translates the binary representation of machine code (chunks of bytes) into the intermediate language RREIL that is then passed on to the analyzer. Basically any collection of chunks of bytes can be fed to the analyzer if wrapped in our simplified binary file format. The input file format for binary code chunks though is built around a simple interface and plugins can easily be added for any other file format.

We are able to parse and extract code sections from Linux (ELF) and Windows (PE) executables and our own It uses pluggable front-ends for the input data (file parsing) and the disassemblers/translators. The disassembler part is designed around the idea of a modular front-end that produces RREIL code from binary code blobs. To this end we perform a collection of (numeric and symbolic) analyses on the program and are able to infer memory access bounds and various other numeric properties statically, i.e. The analyzer enables one to reason about all the possible runtime behavior of a program and find potential bugs. In fact, the purpose of Bindead is to help with the reverse engineering of executable code or binaries.
As Bindead operates on the machine code level, it can be used without having the source code of the program to be analyzed. It features a disassembler that translates machine code bits into an assembler like language (RREIL) that in turn is then analyzed by the static analysis component using abstract interpretation.
