P2P responsible for as much as 90% of all Net traffic

Filed under: — Aviran Mordo

P2P traffic is dominating the Internet these days, according to a new survey from ipoque, a German traffic management and analysis firm. ipoque’s “preliminary results” show that P2P applications account from anywhere between 50 percent and 90 percent of all Internet traffic. The final survey results are not yet available and will presented at the Emerging Technology Conference at MIT later this month.

Leading the way is BitTorrent, which has surpassed eDonkey as the P2P protocol of choice. During the last year, BitTorrent accounted for between 50 percent to 75 percent of all P2P traffic, with eDonkey coming in second at between 5 percent and 50 percent. The wide variance in the figures is due to local preference, according to ipoque: in some parts of the world, eDonkey still reigns supreme when it comes to P2P traffic.

Chinese military hacked into Pentagon

Filed under: — Aviran Mordo

The Chinese military hacked into a Pentagon computer network in June in the most successful cyber attack on the US defence department, say American ­officials.

The Pentagon acknowledged shutting down part of a computer system serving the office of Robert Gates, defence secretary, but declined to say who it believed was behind the attack.

Current and former officials have told the Financial Times an internal investigation has revealed that the incursion came from the People’s Liberation Army.

One senior US official said the Pentagon had pinpointed the exact origins of the attack. Another person familiar with the event said there was a “very high level of confidence…trending towards total certainty” that the PLA was responsible. The defence ministry in Beijing declined to comment on Monday.

Angela Merkel, Germany’s chancellor, raised reports of Chinese infiltration of German government computers with Wen Jiabao, China’s premier, in a visit to Beijing, after which the Chinese foreign ministry said the government opposed and forbade “any criminal acts undermining computer systems, including hacking”.

Spammers add a new dimension to junk mail

Filed under: — Aviran Mordo

Spammers have added a fresh dimension to the fight against junk mail with the creation of image spam rendered in a pseudo 3D layout.

The use of images as opposed to simple junk messages as a way to punt penis pills, refinancing offers and the like has being going on for months. The approach is designed to fool basic spam filters and is, these days, seldom effective. In order to have any hope of success, spammers must use the computing power of compromised machines to create a uniquely modified image in each spam email. Failure to do this would enable spam filters to discard known spam images.

Spammers have now extended this approach by using images that have been modified by adding colours, changing fonts and inserting random dots and lines so that they appear to be in “three dimensions”. The effect is even less convincing than squinting at Jaws 3D through a pair of coloured glasses. It’s also even more nauseating.
