According to Kaspersky Lab, threat actors behind the recent Olympic Destroyer attack planted sophisticated false flags inside their malicious code. Attackers used the so-called Olympic Destroyer, a strain of malware that allowed the attackers to wipe files and make systems inoperable. There are many similarities between the Pyeongchang attack, which they are dubbing Olympic Destroyer, and earlier attacks such as BadRabbit and NotPetya. All of these attacks are focused on destruction and disruption of equipment not exfiltration of data.”]
