Avecho has offered $18,056 (10,000 pounds) to anyone who can past its GlassWall product, and it has even opened up the challenge to its developers.
"Lots of people have already tried to do this," said Mark Elliott, vice president of international marketing for Avecho. "I think this is something we are able to do. The only condition is that people must be willing for us to publicize their failure as well as their success."
In order to take part, contestants need to sign up for an Avecho e-mail account and then send a virus to that address or try to receive one from it. If the virus gets through, the contestant will win the prize, Elliott said.
Currently, Avecho is the only party able to see the virus traffic traveling through its network. Elliott said he would like a third party to judge the contest, but no one has come forward to volunteer for the job yet.
"We are struggling to find a third-party arbiter," Elliott said. "We would like to get a media company (to judge the competition), but as yet we don't have one."
Avecho's GlassWall product has been shrouded in mystery for some time. The company still refuses to detail how the product works, saying only that it is "a software-based, siliconizable malware protection solution." In the past, Avecho executives have said the company was keeping the mechanics secret because it was unable to patent its products.
Elliott declined to comment on the company's plans or its financial backers but said that there were "some changes in progress at the top level."
Many companies have crashed and burned with hacker challenges. In 2001, Argus Systems failed to pay a Polish ethical hacking group, called the, prize money for cracking its Pit Bull server.
Korean Digital Works also suffered embarrassment in 2002, when suspicion arose over the running of its hacking competition. The company hadto anyone who could break its Web server, but instead, hackers decided to break the registration server to control who entered the contest.
