Security expert Brian Krebs dropped a bomb on Yahoo email users last week, though his warning was probably lost in the roar of stories about Black Friday fistfights. According to Mr. Krebs, an Egyptian hacker using the screen name TheHell is selling a Yahoo Mail exploit that could allow an attacker to take over and control a victim’s email and browser activity. TheHell is only charging $700 for the information.

TheHell uploaded a video demonstration to prove he was serious. Mr. Krebs reproduced the video, which you can watch below.

According to Mr. Krebs, the hacker implied his $700 asking price was a bargain:

“I’m selling Yahoo stored xss that steal Yahoo emails cookies and works on ALL browsers,” wrote the vendor of this exploit, using the hacker handle ‘TheHell.’ “And you don’t need to bypass IE or Chrome xss filter as it do that itself because it’s stored xss. Prices around for such exploit is $1,100 – $1,500, while I offer it here for $700. Will sell only to trusted people cuz I don’t want it to be patched soon!”

Yahoo’s security director, Ramses Martinez, told Mr. Krebs that fixing the exploit itself isn’t too hard–the problem is finding the weak Yahoo URL that allows the hacker to take control.

“Once we figure out the offending URL,” said Mr. Martinez, “we can have new code deployed in a few hours.”

Mr. Krebs noted that Yahoo doesn’t pay hackers who notify the company about vulnerabilities like this. Several other companies do, Mr. Krebs writes, “including Facebook, Google, Mozilla, CCBill and Piwik.”

As for ensuring you don’t fall prey to such a hack, always engage extreme caution when opening emails containing links, especially if they come from unfamiliar sources. Like guys who call themselves TheHell, for instance. Just $700 Will Buy the Key to Stealing Any Yahoo Email Account
