Robber is a free open source tool developed using Delphi XE2 without any 3rd party dependencies. In Version 1.7 Robber doesn't require administrator rights by default because of new write permission check feature, so if you want to scan somewhere like 'ProgramFiles' you need to run Robber with admin rights. What is DLL hijacking? Windows has a search path for DLLs in its underlying architecture. If you can figure out what DLLs an executable requests without an absolute path (triggering this search process), you can then place your hostile DLL somewhere higher up the search path so it'll be found before the real version is, and Windows will happilly feed your attack code to the application. So, let's pretend Windows's DLL search path looks something like this: A) . <-- current working directory of the executable, highest priority, first check B) \Windows C) \Windows\system32 D) \Windows\syswow64 <-- lowest priority, last....
