Posted by Mourad Ben Lakhoua in Cybercrime, Web Security on November 2, 2009
According to thelocal news Swedish police website was subject for a DDoS attack last week. The result of this attack was a complete disrupt of the official website.
On the High traffic the server can treat about 800 requests per second but during the attack they detected about 400 thousand requests per second which is 5 times more than the normal high traffic.
The number of DDoS-attack has significantly increased to become one of the biggest threats on Internet, by looking at the history the beginning of DDoS attacks were mainly directed to disrupting IRC servers, but on 1997 there were a vulnerability on Microsoft windows TCP/IP that allowed hackers to send a lot of packets using several tools and dosing remote systems, another popular incident were on 2000 by turning down web service for many popular websites like YAHOO ,CNN, eBay and others, October 2002 Root DNS servers experienced a DDoS attack to make 7 of the 13 main servers out of service. And now we are seeing a lot of distributed denial of service (DDoS) attacks against social networking website like Twitter and Facebook…
Stopping DDoS attack depends on the whole internet community by protecting your machine from malware that could be used to run these attacks, the most popular Botnet’s are:
Conficker 10 million + Machine.
Kraken – 495 Thousand Machine.
Srizbi – 315 Thousands Machine.
Bobax – 185 Thousands Machine.
Rustock – 150 Thousands Machine.
Storm – 85 Tousands Machine.

Bitbucket a web Service designed to host programming projects has faced an outages last weekend, the failure period was more than 19 hours which is relatively long. According to Amazon the incident was due to a DDoS attack on their computing infrastructure.
This Attack can only brings a doubt in the IT services that are provided by Amazon (Amazon Elastic Compute Cloud EC2), we had previously posted on a several cases of DDoS attacks, Jesper posted on the company blog some details about the incident which is not usual.
The story started when they noticed on the server a high load, even by turning off anything that took up CPU. They submitted an “urgent” ticket to the Amazon support system and in 5 minute the support responded by phone to help on the issue.
Later the support identified the problem it was a massive flood of UDP packets targeting the Bitbucket website and consuming the whole bandwidth to the box. This is what we call a distributed denial of service.
The source of attack was not identified but the developer assumed that the attack targeted one of their projects.

Sources say Pentagon plans new cyber command
Posted by Mourad Ben Lakhoua in News on April 26, 2009
The U.S. military is planning to create a new military command to focus on cyberspace and protect its computer networks from cyber attacks, Pentagon officials said Wednesday.
The move comes as the White House prepares to release a broader study on the nation’s cyber security. Officials in recent months have warned increasingly that the nation’s networks are at risk and repeatedly are being probed by foreign governments, criminals or other groups.
The Pentagon has been reviewing for at least a year just how it needs to reorganize military efforts on cyber issues, one official said on condition of anonymity because he was not authorized to speak on the record. Another official said that under the new plan, being completed now, a subcommand could be set up under the U.S. Strategic Command.
The military’s plans to create the new cyber command was first reported Wednesday in The Wall Street Journal and The Washington Post.
Sited at Offutt Air Force Base just south of Omaha, Nebraska, the command oversees space issues and is responsible for protecting and monitoring the military’s information grid, as well as coordinating any offensive cyber warfare on behalf of the country.
Defense Department networks are probed repeatedly every day and the number of intrusion attempts have more than doubled recently, officials have said. Military leaders said this month that the Pentagon spent more than $100 million in the last six months responding to and repairing damage from cyber attacks and other computer network problems.
In the Pentagon’s budget request submitted last week, Defense Secretary Robert Gates said the Pentagon will increase the number of cyberexperts it can train each year from 80 to 250 by 2011.
