It was, however, less sophisticated than its predecessor, and in particular it lacked the self-propagating worm features that made NotPetya a general danger. WhisperGate was, like NotPetya a few years ago, a pseudo-ransomware attack that delivered a wiper behind defacements and spurious ransom demands. The Wall Street Journal sees last week's cyberattacks against Ukrainian targets as pointing to a broader risk of more general cyberwar. The operation is being called "WhisperGate." Microsoft has given the threat actor the temporary tracking identifier DEV-0586. It is, however, confident that the attack involved the use of a wiper, malware whose intent was the destruction of data, not their temporary denial (as in a conventional ransomware attack) or their theft.
Microsoft said last Saturday that it hadn't been able to draw connections between Friday's cyberattacks against Ukraine and any of the threat actors it tracks. Increasing this number should work but has not been tested.Russia operates in the grey zone against Ukraine. Note that the number at the end indicates the size to write in hex.
