A Month After Grum Botnet Takedown, Spam Back To Previous Levels 47
wiredmikey writes "It's been over a month since spam-spewing Grum botnet has been shut down, but spam experts say there hasn't been a noticeable impact on global spam volume. Symantec researchers at the time estimated that Grum was responsible for one-third of all spam being sent worldwide, and its takedown led to an immediate drop in global spam email volumes by as much as 15 to 20 percent. However, the drop was only temporary. While Grum had an estimated hundred thousand zombies sending spam, the machines were likely blocked for sending emails too frequently, or wound up on IP blacklists, said Andrew Conway, Cloudmark researcher. IP filtering is fast and cheap, and is a good first line of defense against spam, Conway said. Grum spam was easy to blacklist, and despite its size, most spam messages from the botnet probably never reached user inboxes."

These aren't companies, these are criminal going concerns, some well organized,
Wait, what?. I thought you said they weren't companies. I'm confused.
but I don't expect you'll see them listed on NASDAQ any time soon.
Oh, they're privately-held companies. No biggie. Those are the real engines of industry and the heart of the entrepreneur class.
Ah I see. "Criminal". The only real difference between "criminal concern" and "legitimate entrepreneur" is the size of their lobbying budget and legal departments.
