Dissecting the Dyre Loader

Authors: Jason Reaves

Dyre or Dyreza, is a pretty prominent figure in the world of financial malware. The Dyre of today comes loaded with a multitude of mod- ules and features while also appearing to be well maintained. The first recorded instance of Dyre I have found is an article in June 2014 and the sample in question is version 1001, while at the time of this report Dyre is already up to version 1166. While the crypters and packers have varied over time, for at least the past 6 months Dyre has used the same loader to perform it’s initial checks and injection sequence. It is the purpose of this report to go through the various techniques and algorithms present in the loader, and at times reverse them to python proof of concepts.
