Researchers with US security software maker Symantec Corp say they have uncovered digital evidence that links cyber attacks on South Korea dating back four years to a single hacking group dubbed the "Dark Seoul Gang."
Eric Chien, technical director with Symantec Security Response, said late on Wednesday that his firm made the connection while reviewing malicious software code used to launch attacks that disrupted some South Korean government websites earlier in the week.
He said that the evidence did not uncover the identity of the gang members.
North Korea has been blamed for previous cyber attacks on South Korean banks and government networks, although Pyongyang denies responsibility and has said it has also been a victim.
