In a blog post, Mike Reavey, Director, Microsoft Security Response said, “Unfortunately cyber crime and cyber attacks are daily occurrences in the online world. We condemn these attacks and the recent attacks against Google and other companies.”
He said according to Microsoft’s investigations into the attacks, “we recently became aware that a vulnerability in Internet Explorer appears to be one of several attack mechanisms that were used in highly sophisticated and targeted attacks against several companies. At this time, we have no indication that Microsoft’s corporate network or our mail properties were attacked as part of these attacks.”
Microsoft has published a Security Advisory that provides people with guidance, and tools, to help protect themselves, and is now working with its Microsoft Active Protections Program (MAPP) and Microsoft Security Response Alliance (MSRA) partners to help provide broader protections for customers. “At this point, these attacks appear to be targeted at corporations; we have not seen any evidence of attacks against consumers,” the blogpost read.
The vulnerability that the Chinese hackers exploited affects Internet Explorer 6, IE 7, and IE 8 on Windows 7, Vista, Windows XP, Server 2003, Server 2008 R2, as well as IE 6 Service Pack 1 on Windows 2000 Service Pack 4, Microsoft said in an advisory this week. Earlier this week, Google had said the attacks targeting it and other US corporations had originated in China, and the targets of the attack were the email accounts of human rights activists. Source code was said to have been stolen from over 30 Silicon Valley companies targeted in the attack, reports said. Amongst companies who have been reported as targets of the attacks are Adobe, Yahoo, Symantec, Juniper Networks, Northrop Grumman, and Dow Chemical.
In its statement, Microsoft said the vulnerability in its Internet Explorer browser exists as an invalid pointer reference and that it could allow an attacker to take control of a computer if the target were defrauded into clicking on a link in an e-mail or an instant message that led to a Web site hosting malware. "It could also be possible to display specially crafted Web content using banner advertisements or other methods to deliver Web content to affected systems," it said in its statement. “Obviously, it is unfortunate that our product is being used in the pursuit of criminal activity. We will continue to work with Google, industry leaders and the appropriate authorities to investigate this situation,” Reavey concluded in his blog. |
