Honor Among Thieves And Other Black Hats

Will Microsoft's effort to fund rewards for information on high-profile virus and worm writers make a difference? The virtual wanted poster is a good idea on many levels.

By now its clear to most everyone that law enforcement is ill-equipped to effectively uncover the perpetrators of the widespread viruses and worms. Microsoft is doing something about it, by starting a fund of reward money for information leading to the arrest of such miscreants.

Now, the $5 million fund is not a major investment for Microsoft—if the reward has some positive effect. And its easy to see it having a positive effect, even if it fails to put a deep chill into the community of black-hat malware writers.

Still, I dont expect that the reward will prove much of a deterrent because the people who write these things dont consider the potential punishments for the laws theyre breaking. Even if they did, they would think theyll get away with it.

Perhaps if Microsofts reward program was visibly successful by bringing in informants and leading to successful prosecutions, then the deterrent effect could work. Patrick Gray of Internet Security Systems, a twenty-year veteran with the FBI, said that in the world of conventional physical crimes, such rewards work very well.

Informants may be hard to come by, but it may depend on the author and his or her psychology. The Blaster worm, if you recall, was amateurly written, probably by a kid proving his machismo. Its hard to imagine he didnt brag to friends, and one of them might well be tempted by the money.

Likewise, authors of more-professionally-written attacks, like Sobig, may be just as vulnerable to being turned in by paid finks. Their safety will be assured only when the number of people who know the authors identity is very small.

Taking a slightly different approach, techno-Law Professor Lawrence Lessig recently proposed bounties for spammers. Heres his specific proposal:

Imagine a law that had two parts—a labeling part and a bounty part. The first part asserts that any unsolicited commercial e-mail must include in its subject line the tag [ADV:], which is the label. The second, bounty part suggests that the first person to track down a spammer violating the labeling requirement will, upon providing proof to the Federal Trade Commission, be entitled to $10,000 to be paid by the spammer.

This would be impossible to prove without a real-world experiment, but who can doubt that some spammers would be found in such a way. The only real doubt is whether the FTC or civil courts (or perhaps even the mob?) could get the spammers to cough up the $10,000. People who are so craven about violating existing laws as well as other peoples privacy will usually find a way to skip town ahead of their creditors.

This is an advantage for the Microsoft-funded approach. The money would be there, and potential informants would know that it could be collected, probably under well-defined rules. The Lessig proposal envisions the bounty hunter collecting the money from the spammer, but odds are you wont see a single ruble.

Another thing I like about the criminal rewards approach is that it puts these crimes on the same level as other crimes. In my mind, the act of writing and releasing a mass-mailer worm is the moral equivalent of breaking into millions of homes and offices and vandalizing them.

The innocuous worms just spray-paint your kitchen, the more malicious ones trash the place. Its morally irrelevant whether its easy to do or if someones products or security practices should have prevented the attack. Strangers shouldnt go around damaging other peoples property, even if that property is just information.

At the same time, the whole situation is depressing: that the wonderful openness and interconnectedness of the Internet has deteriorated to the point where attacks are endemic and bounties raised against the attackers. A kind of a Wild West thing. In the end, the West was tamed, but the Internet may prove a more hostile landscape to the taming influence of law enforcement.
