GREEN BAY, Wis. (WFRV) - An online security hole nicknamed the "Heartbleed Bug" by Google researchers allows hackers to still online users private information.
"It uses what they call memory dumps," Mike Bruesch, computer technician at Camera Corner says, "so it will take anything that is stored on the memory of a server of something like that and steal it."
Unlike a virus that attacks your computer, the bug goes after website servers. Instead of taking large portions of information, it allows hackers to access your information while you're typing it.
"In theory somebody that has exploited the vulnerability could get access to your usernames, passwords, credit card numbers if that had been involved," CNET Senior Writer Seth Rosenblatt says, "potentially very serious."
More than half a million websites use the affected technology. But mike says there's no way of knowing if you've been affected.
"All you can do is ask whatever website you're using whether or not they've patched the hole," Bruesch says, " and if they haven't, I would change your passwords frequently."
But there are some things you can do to ensure you're using a secure site.
"When you're in your internet browser and you look at the address bar on top," Bruesch says, " you'll see the actual address which will usually start with HTTP. Now a secure website will start with 'https' and that's actually what you want."
