W32.Duqu: The Precursor to the Next Stuxnet

October 19, 2011

According to Symantec, Duqu is the precursor to another Stuxnet type attack. However Duqu does not contain industrial like controls. It is primarily a remote access Trojan.

On October 14, 2011, a research lab with strong international connections alerted us to a sample that appeared to be very similar to Stuxnet. They named the threat “Duqu” [dyü-kyü] because it creates files with the file name prefix “~DQ”. The research lab provided us with samples recovered from computer systems located in Europe, as well as a detailed report with their initial findings, including analysis comparing the threat to Stuxnet, which we were able to confirm. Parts of Duqu are nearly identical to Stuxnet, but with a completely different purpose.

A little more than one year after the infrastructure-destroying Stuxnet worm was discovered on computer systems in Iran, a new piece of malware using some of the same techniques has been found infecting systems in Europe, according to researchers at security firm Symantec.The new malware, dubbed “Duqu” [dü-kyü], contains parts that are nearly identical to Stuxnet and appears to have been written by the same authors behind Stuxnet, or at least by someone who had direct access to the Stuxnet source code, says Liam O Murchu.

AMD launches FX “Bulldozer” desktop chips, Eight cores

October 12, 2011

The long-awaited day for AMD fanboys has arrived. The chip company has finally released its first Bulldozer desktop processors under the FX series name, including a flagship eight-core CPU that’s priced at just $245.

Four FX processors are launching today, including a pair of eight-core chips, a six-core one, and a quad-core one. The octo-cores include the 3.6GHz FX-8150 for $245 and the 3.1GHz FX-8120 for $205, while the hexa-core chip is the 3.3GHz FX-6100 for $165. The quad-core FX-4100 runs at 3.6GHz and is priced at just $115. Each has a Turbo mode that lets it run even faster, and all are unlocked so overclockers can goose them to even higher clock speeds. In fact, the FX-8150 recently set a world record for the highest frequency for a CPU.

But how do the new chips compare to their Intel equivalents? According to Bulldozer reviews at AnandTechHotHardware, and Tom’s Hardware, it appears that the FX-8150 is no match for the Core i7-2600K on many benchmarks, though it performs more in line with i5-2500K, which runs around $220. While the Bulldozer chip handles multi-threaded benchmarks well, it suffers compared to Sandy Bridge processors on lightly threaded apps and even on power consumption, supposedly one of its strong suits.

So it seems that AMD hasn’t delivered much of a knockout punch to Sandy Bridge, though enthusiasts will still be happy to have a more competitive alternative than the aging Phenom II processors. And real-world performance won’t exactly mirror benchmark testing, so many buyers may still be happy with the FX series. However, Intel’s Ivy Bridge chips are on the horizon, and they should reset the competitive landscape once again in a mere few months.
