During this session we will explain how we are combating the Number One ransomware-as-a-service, GandCrab.
We'll discuss what we have learned from looking at the malware, from finding specific mistakes and indicators to exploiting those mistakes to build a publicly available vaccine.
We also focused our efforts on linking the ransomware and its affiliates to victims. (This is something that is often overlooked by the industry and law enforcement.)
To learn more about the actor behind GandCrab and its affiliates we carried out extensive underground forum research. We did all of this to complete the chain of custody, from victim to perpetrator. By looking at hundreds of GandCrab samples at once we began to find some interesting discoveries and patterns.
During our session we will cover the following topics:
* Reverse engineering the code
* The mistake we found, which helped build our vaccines
* How we extracted and aggregated affiliates from the samples
* Finding affiliates on underground forums
* Throwing all this together in a comprehensive timeline and we'll talk about tools to help law enforcement
* We'll round off with some interactions between us and the actors.
