Today, it is quite difficult for a common user to determine where from and how his computer system can be attacked. More often it could be a virus attack, internet worms or Trojan, spam, DoS attacks causing a denial of service, restricted information theft and, finally, internal threats.

On June 8, 2004 one of the CCRC websites was on “contract hit”. The attack was organized being accompanied with threats to hinder two main sites of the Internet project

On June 8, from 3pm the above-mentioned website has been temporarily unavailable, only by 7 pm the hosting ISP company managed to neutralize the sequels of attack. The main share of attacks came from the territory of Ukraine through compromised computers of usual users. The blackmail attack goal was to force the CCRC staff to put down/away one of the posted articles.

Often one of the first signs of the initiating stage of a DoS attack is an unfounded growth of traffic, it allows to carry out some additional measures to prevent the attack. Sudden increase of traffic related to violation of hosting services operations causes the ISP to block the IP of the website making it unavailable.

According to CERT, an international authority on Internet security, there is a sharp increase of DoS attacks in recent years. Criminal groups widely apply computer tools and newest information thchnologies.
