Hosting firm shutdown forces botnets to relocate

Criminals affected by plug-pulling already shifting operations, says researcher.

Ben Feinstein, director of operations for the counter threat unit of SecureWorks, a security company, echoed Ferguson. "In the short term, this may have a positive effect in reducing online crime, but in the medium- and long-term, they'll reorganize and move to other hosting providers."

The move won't even be that hard, said Feinstein. "The real pioneers of cloud computing were these criminal organizations," he argued. "One of the features of a lot of these botnets is that they can push out updates to the bots to point them toward new command-and-control servers. So while they may lose some bots, they will be able to reconstruct their botnets."

That doesn't mean this week's take-down was for naught.

"There are two important by-products of that [forced] redeployment," said Ferguson. "It increases the cost of doing business for them, and when they do move, we can observe and track them."

"It's definitely a positive take-away," said Feinstein. "This, and the Intercage take-down [in September] serve as examples that if you allow this kind of activity to run rampant on your network, or you're aiding and abetting criminals, there can be consequences."

Even then, however, Feinstein said there might be a dark lining to the cloud. "McColo's upstream providers were responsive in the end [to the evidence], but are you going to get that from other providers in other parts of the world? Unlikely. So big take-downs like this may get more difficult."

"I'm just taking solace in small victories," countered Ferguson. "What we have to try to do is raise the cost of doing business for these guys."

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
