It truly is presently not crystal clear who the supposed victims are, despite the fact that SentinelOne stated it notified Ukrainian businesses. The correct scale of the attacks is presently unknown.

The discovery as soon as once more underscores the use of wiper malware to cripple targets, even as risk actors are diversifying their attack procedures for greatest effects.
