This week's article combines the previous week's stories as well.  Lots of small in-dev ransomware over the last two weeks, a few RaaS (Ransomware as a Service) implementations were released, and a decryptor for GandCrab was released.

The biggest news was the release of a decryptor for the GandCrab ransomware. This decryptor only works on some versions of the software and the actors behind GandCrab have stated they are already working on a new version with a more secure Command & Control server.

In other news, the Colorado department of transportation was hit by SamSam, which caused them to have to shut down 2,000 computers.
