Kaseya

Episode 1812

Employees have been warning IT company Kaseya that the company would be hacked for three years.

The hack was performed by Russian criminal gang REvil, demanding 70 million in bitcoin for the decrypter. Leo says that there's no excuse for it, as the executives of Kaseya left the company a sitting duck for an attack.

Leo also adds that every year, ransomware gets worse and more prevalent.

Vick from Vista, CA

Vick is concerned with network security, especially with ransomware. Leo says it's important to adopt a layered approach to online security, especially with employees. Train your employees to be able to identify so-called Phishing attacks and malware. Be aware of spear-phishing attacks, especially when working from home via VPN. Password management is important, too, with rotating passwords. Have good offline backups, so if your network is compromised, you can get back up and running. It's a complicated full-time job, but it's worth hiring someone to do it.

Microsoft has put out an emergency update to plug the holes, and users are advised to install the fix immediately.
