Security researchers at FireEye have detected a new series of drive-by attacks based on a new Internet Explorer zero-day vulnerability. The attackers breached a website based in the US to deploy the exploit code to conduct a classic watering hole attack. The discovery was announced just a few days after Microsoft revealed the Microsoft Zero-day CVE-2013-3906 , a Zero-day vulnerability in Microsoft graphics component that is actively exploited in targeted attacks using crafted Word documents sent by email. Microsoft graphics component zero-day vulnerability allows attackers to install a malware via infected Word documents and target Microsoft Office users running on Windows Vista and Windows Server 2008. Recently reported new Internet Explorer zero-day vulnerability detected by FireEye affects the English versions of IE 7 and 8 in Windows XP and IE 8 on Windows 7, but according the experts it can be easily changed to leverage other languages. Experts at FireEye conf

The US government, particularly the National Security Agency  has been paying a French security firm for backdoors and zero day hacks. According to a contract newly released in response to a Freedom of Information request, last year the NSA purchased a 12-month subscription to a " binary analysis and exploits service " sold by Vupen, a zero-day Exploit Seller based in France. VUPEN is one of a handful of companies that sell software exploits and vulnerability details, who do original vulnerability research and develop exploits for bugs that they find. They Sold those exploits to the Governments and Law enforcement agencies. VUPEN has promised that the company only will sell its services to NATO countries and will not deal with oppressive regimes. It is unclear how much money the NSA spent on the Vupen exploits package because the cost has been redacted in the released contract. Last year, Vupen researchers successfully cracked Google's Chrome browser, but declined to
