<p>Many attacks here originate from overseas. "It is very complicated to locate an original attack," said a participant at the 9th Xcon conference, an annual gathering of cyber security analysts.<br /><br />The participant, also a consultant for a global software firm, said overseas hackers link to computers in China so the victims believe they were attacked from this country, reported China Daily.<br /><br />"For example, there might be a hacker in America, he might attack a computer in China first and then use the Chinese IP to attack a computer in Australia and so on," the consultant said.<br /><br />Last year, 75 percent of global companies experienced severe cyber attacks causing losses worth $2 million, according to Symantec's 2010 report.<br /><br />There have been claims by websites and search engines, including Google, Optus and the official website of the Republic of Korea, that they have been victimised by Chinese hackers. <br /><br />The expert said attackers use fake IPs to make themselves untraceable. <br />The hackers also utilise "fryers", a computer with security leaks that is accessible to hackers. Using fryers is like using guns registered under another person's name before squeezing the trigger, the analyst explained.<br /><br />This kind of attack is called Distributed Denial of Service (DDOS), "pretty simple technically, with attack tools already made and put out there", the consultant said. <br /><br />No advanced techniques are needed to conduct DDOS attacks, "as long as you have enough money to buy lots of fryers and control them", said Sun Bing, a Beijing-based researcher who also attended the conference. <br /><br />According to the Chinese National Computer Network Emergency Response Technical Team, more than one million Chinese IPs were under overseas control in 2009. <br /></p>
