South Korea’s communications regulator announced yesterday authorities and online security analysts are assessing the damage caused by what is being described as the largest data breach in the country’s history.
SK Communications discovered earlier this week that malicious code was used to hack its sites, the Nate portal, the third most visited search engine and email platform in the country and Cyworld, described as Korea’s equivalent to Facebook. Officials explained that hackers infiltrated sites and stole the phone numbers, email addresses, names and encrypted information of up to 35 million users.
They claim to have traced the source of the incursion back to computer IP addresses based in China.
According to Reuters, accusations against China over hacking incidents have mounted in recent months, with allegations it intruded into the networks of Lockheed Martin and other U.S. military contractors and tried to gain access to the Google email accounts of U.S. officials and Chinese human rights advocates.
This recent attack on Korea’s popular sites follows a series of recent cyber attacks directed at South Korea’s government and financial firms.
