Hacking attacks on the websites of U.S. and South Korean government agencies and banks in 2009 and in March this year were probably launched by "North Korea or its sympathizers," computer security firm McAfee Labs said Tuesday.
McAfee in a report said analysis of code clues used in the so-called massive denial of service attacks suggests the North or its sympathizers were behind them, especially the attacks that paralyzed U.S. government websites in 2009. Analysis suggests a more than 95 percent probability that the attacks in 2009 and 2011 were perpetrated by the same culprits, it said.
McAfee believes that this year's attack that targeted more than 20 websites in South Korea was a kind of reconnaissance. "The attack itself was very limited and may have been utilized to test and observe how quickly the attack would be discovered, reverse engineered, and mitigated," it said.
