This week we had our fair share of smaller variants being distributed or created, but the big news was by far the release of Magniber and the use of the Hermes ransomware as a cover to steal money from a Taiwan bank.  With the release of Magniber we also see the downward spiral of Cerber, which has little or not distribution remaining at this time.

Magniber Decrypter Created for Offline Victims

Simone, the VP of Research at mobile security compay Zimperium, created a decryptor for victims who may have been infected with the hardcoded key in Magniber. This decrypter requires you to know the key and IV that is embedded in the particular sample that you were infected in. Only victims who were infected from a non-Korean IP address or who could not connect to the Command & Control servers would have been encrypted with the hard coded key. 

This decryptor easily compiles in Visual Studio, but if anyone needs it, feel free to reach out and I will provide the binary.
