There was quite a bit more ransomware activity this week compared to last week. Like usual, this week has been dominated mostly by small variants that most likely will never make it into distribute. We did, though, see a new CryptoMix and Locky variant released, that are actively distributed. The biggest news was the discovery of a new Android ransomware called DoubleLocker, which uses some new and interesting techiques.
