KnowBe4 Issues Alert: CryptoWall 2.0 Ransomware Moves to TOR Network



Tampa Bay, FL (PRWEB) October 15, 2014

KnowBe4 issued an alert to IT Managers that a new version of the world's most widespread ransomware CryptoWall has migrated to the TOR network. It has been upgraded to version 2.0, and 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 had backups but it would take days to recover the data and get them back up and running. The company's operations would be severely impacted.

"The cyber criminals hit pay dirt with this one and the admin ended up paying the ransom, 1.3 Bitcoin, rather than face the serious costs caused by days of downtime, said Stu Sjouwerman, KnowBe4's CEO. "This is the next generation of ransomware and you can expect this new version to spread like wildfire."
