Removing Debugging Information from Visual C++/C# Projects
It’s often surprising how many malware programmers forget to do the simplest things. Mostly because many are so concerned with functionality, stealthiness and other production concerns, that details slip easily of their minds – a clear advantage to forensics. One of these details is the Program DataBase (PDB) information added by Visual Studio, which most malware authors used for Windows development. While it may seem innocuous, this string reveals a lot about the operating system used by the author, its user name and most notably, symbols that can be used by IDA and ease understanding of the disassembly.
