Now this is a pretty interesting contest from the guys at Defcon, antivirus evasion! It’s a question that gets asked a LOT…how do I avoid AV?
There are various ways to do it and I’ll be interested to see which are used in the contest, the most elegant solutions of course get better prizes.
Security firms have split over the merits of a hacking contest aimed against anti-virus packages planned for August’s Defcon conference.
Anti-virus firm Sophos reckons the exercise will serve only to increase the volume of malware in circulation, further taxing the resources of already hard-pressed security firms. However, net security services firm MessageLabs reckons the proposed Race to Zero competition has some merits as an exercise. It compared the wheeze to penetration testing against corporate networks.
During the proposed Race to Zero contest, delegates to the Defcon hacker conference will be invited to develop techniques to modify supplied virus samples so that these variants are able to evade detection by anti-virus packages. The contest will progress in difficulty leading to awards at its conclusion including “most elegant obfuscation” and “most deserving of beer” as well as an overall winner.
I am of course pro-knowledge, so I think this contest is a great idea. As stated similar research conducted in the past has been useful..so why not this time?
Personally I think signature based virus detection is very weak and heuristic scanning is nowhere near as good as it should be. The AV vendors needs to get their collectives acts together and develop some cool new stuff that effectively blocks unknown malware rather than permanently playing a catch-up game.
Contest organisers said that the exercise will help to demonstrate shortcomings in signature-based virus detection. They also want to highlight weaknesses among anti-virus vendors exposed by the testing process, which will involve passing modified samples through a number of antivirus engines housed on a closed portal. Modified samples will not be released into the wild, the organisers explain. Results of the contest, a fringe event planned outside the main Defcon conference programme, are due to be presented during the annual Las Vegas-based hacking jamboree.
Despite these assurances some security vendors are less than impressed. Graham Cluley, senior technology consultant for Sophos, said: “The last thing the world needs is more malware. It’s really disappointing to see that Defcon appears to be condoning the creation of malware in this way.
“If people really want to test the quality of different anti-virus products there are well established ways of doing it – and testing industry initiatives like ATMSO are working hard at improving standards,” he added.
I would have thought Sophos were amongst the more progressive AV vendors, but it seems not so. Anyway it’s definitely something to watch and we’ll be keeping an interested eye on it.
