KnowBe4issued an alert to IT Managers that a new version of the world’s most widespread ransomware CryptoWall has migrated to the TOR network. It's been upgraded to version 2.0. Continues to encrypt files so that a ransom can be extracted if there are no backups or if the backup process fails, often a common occurrence.
KnowBe4 received a panic call from an IT admin who was hit this week with CryptoWall. The admin’s workstation became infected with the malware. The workstation was mapped to 7 servers and within an hour, the entire server farm was shut down. The admin explained he'd backups but it'd take days to recover the data and get them back up and running. The company’s operations would be severely impacted.
