First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
Microsoft: We took out Storm botnet

Microsoft Tuesday took credit for crushing the Storm botnet, saying that the malware search-and-destroy tool it distributes to Windows users disinfected so many bots that the hackers threw in the towel.
"They realized they were in our gun sights," said Jimmy Kuo, a principal architect with Microsoft's malware protection center, the group responsible for the Malicious Software Removal Tool (MSRT). Microsoft updates and automatically re-distributes the software tool to Windows users each month on Patch Tuesday.
Last year, said Kuo, the criminals behind the Storm Trojan -- malware designed to compromise PCs and add them to a botnet, or collection of infected machines -- tried to keep pace with Microsoft and the MSRT. "They were anticipating our monthly release [of MSRT]," said Kuo, "with new versions that were ready to go immediately before our release."
The bunch controlling the Storm botnet knew that it took Kuo's group several days to create new definitions for the MSRT, and that Microsoft held to a once-a-month release schedule for the tool. And they used that lag time and set schedule to their advantage.
"They knew that it takes [us] a week or more to create new definitions, and they were prepared to update their botnet immediately prior to MSRT releasing," he said, adding that the hackers would get a new version of the Trojan onto already-infected members of the Storm botnet to try to hold on to the machines after Windows had downloaded the newest version of the MSRT.
The idea was to preempt detection by swapping out the Storm bot already on the PC with a version less likely to be identified by the MSRT.
It didn't work, said Kuo. "They found out that even that was a losing battle," he said. "Even though they were able to maintain parts of their botnet, they knew they were in our gun sights. And ultimately they gave up."
