This week we had some rather large or interesting ransomware infections released.  We have a new CryptoMix variant called Revenge being distributed via RIG exploit kits and we have someone modifying Petya in order to get their own ransomware without having to create their own ransomware. We also have a Star Trek themed ransomware called Kirk Ransomware.

Some good news is that Fabian Wosar of Emsisoft released a decryptor for the Damage Ransomware and an update decryptor for CryptON.

Contributors and those who provided new ransomware information and stories this week include: @struppigel@malwrhunterteam@demonslay335@PolarToffee@fwosar@malwareforme@jorntvdw, @FourOctetsDanielGallagher, @campuscodi, @JAMESWT_MHT, @Seifreed, @JakubKroustek@hasherezade@siri_urz@jiriatvirlab@Malwarebytes@Jan0fficial@kaspersky, @msftmmpc, @BroadAnalysis, and @BleepinComputer
