NASHVILLE, Tenn. (NewsChannel5/AP) - It now appears that the "Heartbleed" security problem affects not just websites, but also the networking equipment that connects homes and businesses to the Internet.
A defect in the security technology used by many websites and equipment makers have put millions of passwords, credit card numbers and other personal information at risk.
The extent of the damage caused by Heartbleed isn't known.
"Anything from Facebook to Twitter all the way up to your bank accounts is impacted," explained Kirk Farrell who runs a computer repair business in Smyrna.
The threat went undetected for more than two years, and it's difficult to tell if any attacks resulted from it because they don't leave behind distinct footprints.
"You're pretty safe if you change your password, do it right now. (Hackers) are going to be able to figure out your user name and your password," he adds.
Now that the threat is public, there's a good chance hackers will try to exploit it before fixes are in place.
