“The malware is disguised as ransomware but, if activated by the attacker, would render the infected computer system inoperable,” Microsoft said. In short, it lacks a ransom recovery mechanism.

In Friday’s mass internet defacement, a message left by the attackers claimed that they had destroyed knowledge and positioned it on-line, which Ukrainian authorities stated had not occurred.

The message instructed Ukrainians to “be afraid and expect the worst.”
