75million Zombie Computers in USA are owned by China

A former senior U.S. information security official says there are nearly three-quarter million personal computers in the United States taken over by Chinese hackers. “This is a fact that should get everyone’s attention,” Paul Strassmann told Government Executive magazine columnist Bob Brewin. Strassman, who was director of defense information in the early 1990s, is now back at the Pentagon as a senior advisor, according to Brewin.

“As of the morning of Sept. 14, there were exactly (remember, Strassmann is an engineer and likes precision) 735,598 computers in the United States infested by Chinese zombies,” writes Brewin in his Monday column.

Zombies are malicious software packages downloaded by unsuspecting users from infected e-mail messages or Web sites.

They infect computers at a very basic level, making them hard to find and root out, and they enable the hackers who wrote them to create large networks of “slave” computers that can be used in massive, if unsophisticated, cyber attacks using a technique called Denial of Service, or DoS.

Linux beats Windows NT


In this senario, the overall size of one million files was about twice as large as the 2 GB of main memory. The total number of requests in test runs for which a reboot had previously cleared the buffer cache was clearly below 500,000. Files would generally have to be loaded from hard disk before being sent through the net.
In this setup, the freeware system clearly shows better results: While NT can hardly manage more than 30 requests per second, Linux can handle more than 166. With 512 client processes, it even manages 274 pages per second. Since more than 400,000 pages are retrieved during this test, however, we cannot be entirely sure that the increase especially towards the end of the graph isn’t down to a caching effect. But who would complain about an overly efficient buffer cache?
When calling CGI scripts, Windows NT is no match for Linux. As the load is not confined to kernel mode in this case, Linux can benefit from additional CPUs. The graph at the top nicely depicts the linear increase for a CGI script with integrated delay.

The Linux Incompatibility List is an attempt to catalog and document hardware/peripherals of all kinds that do not work with the Linux operating system, or only work with non-free drivers.
