This week has been dominated by the news of aluminum producer Norsk Hydro being crippled by the LockerGoga Ransomware. While this ransomware has had high profile targets, it is not the most active one out there targeting companies and has not seen wide distribution. A new ransomware called JNEC.a spreads through an exploit for the recently reported code execution ACE vulnerability in WinRAR. After encrypting a computer, it will generate a Gmail address that victims need to create in order to receive the file decryption key once they pay the ransom.
