Hacker Restores Banner Ad Blocking
Workaround thwarts AdKey's effort to nullify ad blockers, but updates are under way.
Rick Perera, IDG News Service
Nobody said the war was over. When it comes to pop-up and banner advertising on Web sites, tempers run high: Dedicated surfers can't stand the commercial messages, but site operators who depend on advertising revenues want people to see them.
Now a hacker has fired the latest round.
An increasing number of users have implemented Web filtering software--such as the shareware AdKiller, InterMute's AdSubtract, Junkbuster's Proxy, or Network Software Development Group's Surfer's Aid--to filter out ads.
That didn't sit well with German Internet company MediaBEAM, which finances its unified messaging services Web site www.directbox.com entirely through advertising. So the company developed an antidote in the form of software called "AdKey" that blocks the ad blockers--denying access to its site to users who have implemented a filter.
Enter a 25-year-old German man, who has announced in e-mail to journalists that AdKey had been cracked just days after it was launched.
"Encouraged either by the bad, ineffective, and almost amateurish HTML-coding style on MediaBEAM's service directbox.com, as well as a personal dislike for forced advertising and the belief that MediaBEAM is not capable of developing the revolutionary software it claims to have developed, a programmer turned the AdKey software almost worthless in a few hours of investigation," he writes.
"I'm not really a hacker, but I'm familiar with (HTML)," says the programmer, who did not want to be identified. He says that he considered cracking AdKey "a sportsmanlike challenge."
AdKey Tries Again
His e-mail includes instructions for how to circumvent the AdKey algorithm, using webwasher.com AG's popular filter. Following the instructions allows you to view directbox.com without ads.
Not so fast, says MediaBEAM Chief Technology Officer Jochen Meyer. He says his company has prepared a Version 2.0 of AdKey, circumventing the anonymous programmer's trick.
"Our programmers actually enjoy finding out when bugs in their work have been discovered; there's a little bit of playfulness that goes into it," he says. "It's really a beta version, where we're just testing how the thing works. This is only a simple solution, but I can assure you that AdKey as a product will function quite differently."
His company will work closely with AdKey users, offering regular updates to counteract any hacks or more sophisticated ad filters yet to be developed, Meyer says.
"You have to imagine it like when someone creates a virus, and people go to [Symantec Corp.'s] Norton... it's a strike and counter-strike scenario," he adds.
Indeed. The anonymous programmer is already on the case: "I think MediaBEAM will make it as hard as possible to crack," he says. "But I won't give up."
And the arms race continues.
