Using anchor DNS, lets the malware to bypass the legit DNS and with it bypassing network defense security and evade recognition.
Other countries like the UK and Australia also predict a potential attack by Ryuke or Trickbot. Australian Cyber Security Centre (ACSC) warned Australian companies about Emotet malware, which is used contemporaneity with Trickbot. "Upon infection of a machine, Emo ..
