Ransom gangs increase hostility towards victims that seek help

In the latest development to the methods used by ransomware gangs, the Grief ransomware gang (with apparent links to DoppelPaymer) has warned that they will delete decryption keys, thereby rendering decryption absolutely impossible, for victim organisations that bring in professionals to negotiate the ransom or who try to decrypt data themselves. This builds on Ragnar Locker group's recent warning that it would leak all exfiltrated data from victims who contact law enforcement authorities.
