Atul Dwivedi, an Indian hacker paid a visit to the Royal Australian Air Force (RAAF) last Monday by defacing their website.
This accident comes amid a raise in violence targeted towards Indian native in Australia and apparently Dwivedi protested this situation by leaving a message on the website:
“This site has been hacked by Atul Dwivedi. This is a warning message to the Australian government. Immediately take all measures to stop racist attacks against Indian students in Australia or else I will pawn all your cyber properties like this one.”
This site is now up and running as per normal. Of course the webserver wasn’t connected to any internal network and didn’t contain any classified information according to a spokewoman:
“No sensitive information was compromised as the air force internet website is hosted on an external server and, as such, does not hold any sensitive information,1“
Microsoft products are used in pretty much every Western armed forces. So it’s save to assume the webserver used by the RAAF is probably running IIS. Of course, IIS implies as Windows machine and a Windows Server machine means that everything is almost certainly all Microsoft based. Of course we can now verify those claims and according to David M Williams from ITWire2 the website is hosted through Net Logistics, an Australian hosting company. The aforementioned article tries to explain the hack with the use of exploits. Which might have been the way Dwivedi did it, but the analysis is quite simple and lacks depth. The site still has an excellent link to a blog detailing the WebDAV exploit, see below for the link.
It’s not impossible to think that Dwivedi might have tricked someone into giving out too much information also. Social engineering can do lots and is usually easier than technical exploits. The Art of Deception by Kevin Mitnick should convince most people of that. Someone could look up on Facebook or another social networking site for some people in the RAAF and then try to pose as them and pose as them.
Then also, why not look for the FTP server? And God knows what else the server is running; maybe a SMTP server also (and probably it does). Now I wouldn’t suggest doing this, but running a port scan would probably reveal a lot of information. Moreover, using web vulnerability tools like Nikto could help find misconfigured settings in ASP or forgotten test/setup pages/files. Up to there, only two things are important: information gathering and imagination.

The vulnerability resolves around the return value of the escape function in the JIT engine. It’s exploited using the <font> tag. The code for the exploit is public and can be found at milw0rm. The exploit use a heap spraying technique to execute the shellcode.
