It has been a slow week in terms of new releases, which is always a good thing. Still lots of small crapware being released that will never have much wide distribution. Of greatest note in terms of new ransomware, a new version of CryptoMix was released that uses the .Exte extension.

We also have some good news, which is the release of a NemucodAES decryptor by Emsisoft. This allows victims of this ransomware to get their files back for free.
