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
CryptoWall 2.0 went live
Sjouwerman advises these three steps as something IT admins have to do:
1." Make regular backups, and have a backup off-site as well. TEST your restore function regularly to make sure your backups actually work.
2. Patch browsers as soon as possible, and keep the amount of plug-ins as low as you can. This diminishes your attack surface.
3. Step all users through effective training on security such as Kevin Mitnick Security Awareness Training to prevent malware infections to start with."
For end users, Sjouwerman advises, "Think before you click. Don't open anything from someone unless you are expecting it. Hover over an email address to make sure its from a valid domain, one you know and recognize."
KnowBe4 offers a free Phishing Security Test(PST) to find out just how many of your users are Phish-prone. KnowBe4 also offers a Crypto-Ransom guarantee and is confident its training works so well, they will pay your ransom if you get hit with ransomware while you are a customer.
