What the Tech? Cyber attack follow

Posted: Updated:

Fallout from Tuesday's massive cyber attack continues and as of this writing, the attacks have been confirmed on over 12,000 computers in at least 65 countries.

The attacks were primarily ransomware, a type of malware that locks a computer and keeps the user from accessing files unless they pay the hacker a ransom, usually around $300.

The ransomware spreads primarily through email attachments that are sent and then opened by the recipient. The malware installs itself on the computer and lately has been able to infect the entire network.

"It literally takes seconds", says Jeremy Hopwood, president of Five Iron Technologies. He told me he sees it happen every single day.

"We're seeing that 33% of people who are getting phishing emails open them, and of those 11% are actually clicking on links," Hopwood said.

When that happens, the computer gets locked and the screen shows a ransom note. In the past, it generally happened on just that one computer, but a recent leak from the NSA is being used by the bad guys, and With those codes, the ransomware attacks the entire network.

"Once they've been weaponized and detonated within the business it spreads within seconds," Hopwood said.

What can you do? It's something you shouldn't do. Never click on a link or attachment within an e-mail. It might appear to be a tracking number from UPS or FedEx or another company. You can also install a program like CyberReason, it's free and will prevent ransomware programs from opening on your computer.

You've probably noticed that a new cyber attack is happening every week. It's only going to get worse.
