Binary Analysis Next Generation (short: BANG) is a framework for unpacking files (like firmware) recursively and running checks on the unpacked files. Its intended use is to classify/label files and making them available for further analysis such as provenance research, license analysis and security analysis. There are quite a few open source licensed tools out there for analyzing firmware files like binwalk, Hachoir or Sleuthkit. Most of these focus on either forensics, or on unpacking firmware, but none of them focus specifically on where open source, firmware reverse engineering and security meet. Experience creating earlier tools shows that the sometimes simplistic and naive approaches from other tools (assuming correct files instead of broken data, reliance on magic headers) is not realistic. This is why I created BANG, which tries to take these into account. Focus in BANG is on correctness, but also on speed. Currently around 150 different file formats can be unpacked or l...
