The Hackers Behind 4 Years of Cyberattacks Against South Korea

Part of the mystery shrouding the cyberattacks on South Korea has been lifted. Online security firm Symantec revealed on Wednesday that one single group — codenamed the DarkSeoul Gang — is responsible for four years of cyberattacks against the country.

The cyberattacks have been persistent over the past few years, with the country's authorities blaming its neighbors and enemies from North Korea. The most recent of the many attacks came on Tuesday, but perhaps the most massive one hit South Korean banks and TVs in March, wiping off multiple hard drives.

Based on chunks of code gathered after Tuesday's attack, researchers at Symantec were able to connect the dots and reveal that parts of the same code were used in various attacks over the last four years, starting with the first attack on July 4, 2009.  "We know that they are one gang," Eric Chien, technical director with Symantec Security Response told Reuters. "It is extremely well coordinated."
