Why Don’t Spammers Get Shut Down Faster?

Spam schemes survive significantly longer than other types of Internet fraud. Why?
October 16, 2009

While researching today’s story about crafty phishing techniques, I came across some statistics that reveal the lifespan of various types of nefarious Internet schemes. The chart below, put together by Milcord, a company that collects real-time data about botnets, shows that spammers survive for a couple of months, while phishers typically make it only about five to ten days. Malware schemes are in between.

What’s the reason for this time difference?

Alper Caglayan, Milcord’s president, thinks it’s due to the nature of the victim. “Phishing targets well-known brands, like Citibank, Bank of America, eBay, or Paypal,” he says. “Obviously, these folks are willing to spend a lot of money defending their brands.”

Though ordinary people are the ones who ultimately get burned, phishers can affect the reputations of companies with deep pockets. Caglayan says that some security companies offer service-level agreements that promise to get a phishing site hosted in the U.S. taken down in under an hour.

Spam, on the other hand, has no such highly-motivated opponents. While it’s a nuisance to everyone, no particular company suffers publicly for it, and therefore, the money to halt it simply isn’t there.

Most individuals may want someone to do something about spam, but they end up relying on anti-virus software or intervention from law-enforcement agencies.The motivation to go after and shut down the botnets just isn’t the same.
