Egyptian Hackers Selling Zero-day Exploit of Yahoo Mail For $700
Those people who wander in many underground hackers community, knows very well that several unethical equipment such as Botnet, Zero-day exploit, black hole exploit kit, malware, undisclosed vulnerabilities and so on were sold there for different prices. Those products were generally priced between $5-$500, but today I will talk about an expensive product, which listed itself top on the black market. I am talking about a new cross-site scripting exploit that enables attackers to steal cookies and access Yahoo email accounts. According to the blog post of Krebs on Security -A zero-day vulnerability in yahoo.com that lets attackers hijack Yahoo! email accounts and redirect users to malicious Web sites offers a fascinating glimpse into the underground market for large-scale exploits. The exploit, being sold for $700 by an Egyptian hacker on an exclusive cybercrime forum, targets a “cross-site scripting” (XSS) weakness in yahoo.com that lets attackers steal cookies from Yahoo! Webmail users. Such a flaw would let attackers send or read email from the victim’s account. In a typical XSS attack, an attacker sends a malicious link to an unsuspecting user; if the user clicks the link, the script is executed, and can access cookies, session tokens or other sensitive information retained by the browser and used with that site. These scripts can even rewrite the content of the HTML page. The hacker posted the following video to demonstrate the exploit for potential buyers.
“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!” -said the hacker.
In response Ramses Martinez, director of security at Yahoo!, said the challenge now is working out the exact yahoo.com URL that triggers the exploit, which is difficult to discern from watching the video. “Fixing it is easy, most XSS are corrected by simple code change,” Martinez said. “Once we figure out the offending URL we can have new code deployed in a few hours at most.”
