An unknown person — possibly a white hat hacker — has taken control of servers distributing Dridex Trojan. The Trojan is one of the three most widely used computer Trojans that target online banking users. Virus researchers from antivirus vendor Avira observed that some of the Trojan’s distribution servers were pushing out an “up-to-date Avira web installer” instead of the Trojan. This means some victims were lucky and instead of having their computers infected, received a legitimate and digitally-signed copy of the company’s antivirus program.”]
