A group of cybercrooks is stealing from other gangs of cybercriminals by using a proxy Tor browser to steal Bitcoins used to pay off ransomware threats. The meta-criminals use a Tor proxy browser to carry out a man-in-the-middle attack to glom the cryptocurrency payments, sent by victims of ransomware. This has the effect of making sure the victims never have even the slightest chance of getting the decryption key that they paid the ransom to get. Ransomware authors seem to have become aware of this game, and have taken some countermeasures.”]
