"value" : "CryptoMix is releasing new variants very quickly now and is reminiscent of how the Locky developers used to distribute Locky. Yesterday, ID-Ransomware's Michael Gillespie & Malwarebytes malware researcher Marcelo Rivero discovered two new variants of the CryptoMix ransomware being distributed within a week or two of each other. These variants append either the NOOB or ZAYKA extension to encrypted files, but use the same contact email of admin@zayka.pro for payment instructions." ,
