The big news over the past few months were the Aurora attacks and how they seemed to originate from China, last month Microsoft took the unusual step and released an Out-Of-Band patch for the IE6 0-Day vulnerability used in the attacks.

Within the last few days the origin of the code was traced to 2 Chinese schools which both claimed they had no knowledge of the exploit.

It was always thought the exploit originated from China due to parts of the code only being discovered on Chinese language sites, the latest news is that the actual origin of the code has been discovered by US investigators.

US investigators have pinpointed the author of a key piece of code used in the alleged cyber attacks on Google and at least 33 other companies last year, according to a new report.

Citing a researcher working for the US government, The Financial Times reports that a Chinese freelance security consultant in his 30s wrote the code that exploited a hole in Microsoft’s Internet Explorer browser. The report also says that Chinese authorities had “special access” to this consultant’s work and that he posted at least a portion of the code to a hacking forum.

The story follows another report from The New York Times that traced the attacks to a pair of Chinese schools – Shanghai Jiaotong University and Lanxiang Vocational School – claiming that the latter had ties to the Chinese military. A day later, representatives of both schools denied involvement to the Chinese state news agency, and the Lanxiang representative denied ties to the military.

It all sounds like a conspiracy from the TV show 24 with schools tied to the Chinese military and ‘special’ access to underground forums.

It’ll be interesting to watch which direction it heads after this and if it’s going to increase the tension between the US and China governments. The whole cyberwar has been going on for quite a while now with both sides trying to covertly steal information from each other.

So far the author of the code has not been named and his real identity or purpose is also a little vague.

According to The Financial Times report, the unnamed security consultant who wrote the exploit code is not a full-time government worker and did not launch the attacks himself. In fact, the FT says, he “would prefer not to be used in such offensive efforts.”

The reports says that when he posted the code to the hacking forum, he described it as something he was “working on.”

With a January blog post, Google announced that attacks originating from China had pilfered unspecified intellectual property from the company, and Microsoft later said the attack had exploited a hole in its Internet Explorer 6 browser. According to security researchers, at least 33 other companies were targeted by similar attacks.

If I understand correctly what is being implied above, the author of the code posted a PoC (proof of concept) type exploit to a hacking forum.

Someone took this PoC, turned it into a working exploit and attacked 33 US based companies. If the conspiracists are right this ‘someone’ would be the Chinese government and they used to the exploit to steal commercially valuable data from some big US players.

Any thoughts?

I’m sure you’ve heard about the Microsoft IE7 Exploit that allows Remote Code Execution on XP & Vista, it turns out it’s actually much worse than first expected.

The exploit also affects IE5.01, IE6 and IE8 on all OS versions! That’s a pretty worrying turn of events for MS especially as they are seemingly leaving it unpatched.

You can find a clarification of the various workarounds for the IE flaw on Technet here.

Researchers are warning that the unpatched security vulnerability in Microsoft’s Internet Explorer affects more versions of the browser than previously thought, and that steps users must take to prevent exploitation are harder than first published.

According to an updated advisory from Redmond, the bug that’s been actively exploited since Tuesday bites versions 5.01, 6, and 8 of the browser, which is by far the most widely used on the web. A previous warning from Microsoft only said that IE 7 was susceptible to the attacks. IE is susceptible when running on all supported versions of the Windows operating systems, Microsoft also says.

What’s more, while there is some protection from Vista’s User Account Control, the measure doesn’t altogether prevent the attack, according to this post on the Spyware Sucks blog. Microsoft and others have suggested that those who must use IE in the next few weeks set the security level to high for the internet security zone or disable active scripting. These are sensible measures, but they don’t guarantee you won’t be pwned, according to this post from the Secunia blog.

Once again Firefox users for the win, this is a flaw in the whole family of Internet Explorer and must effect a shocking amount of users. I guess setting your Security Zone to high and disabling Active Scripting helps but then it also disables a lot of features on a lot of sites.

So you are losing out on the user experience of the web just to be more secure, mostly because Microsoft doesn’t want to release an ad-hoc patch.

Well Google Chrome final version is out now too, so there’s another option for people.

Secunia goes on to revise what it says is the cause of the vulnerability. Contrary to earlier reports that pinned the blame on the way IE handles certain types of data that use the extensible markup language, or XML, format, the true cause is faulty data binding, meaning exploit code need not use XML.

Microsoft has yet to say whether it plans to issue a fix ahead of next month’s scheduled release. For the moment, the volume of in-the-wild attacks remains relatively modest and limited mostly to sites based in China. But because attackers are injecting exploits into legitimate sites that have been compromised, we continue to recommend that users steer clear of IE until the hole has been closed.

Plenty of other researchers have weighed in with additional details about the flaw. Links from SANS, Sophos and Hackademix.

I think an imminent danger is if people start using iframe vulnerabilies and XSS to inject this exploit into some more prominent sites – that could cause a huge spread of infections!

Anyway just let people using IE know that this is another reason they shouldn’t be using it! Show them how to download and install Firefox and please teach them to use Tabs!
