Merritt included that other country-point out affiliated APTs this kind of as TA505 (Russia) and Lazarus Team (North Korea) have made use of ransomware in the previous.
“As lots of ransomware variants are deployed employing commodity malware variants, these types of as TrickBot and Emotet, it’s usually challenging to pinpoint attribution to just one precise APT,” Merritt stated. “Given the prominence of ransomware across the threat landscape, it is very likely that economically-determined country-condition threat actors will use ransomware in potential attacks.”
