A hacker has stolen the private data of over half of the population of South Korea in a series of major cyber-attacks.
The 24-year-old hacker, known only by the surname of 'Kim', broke into 220 million data records using a cache of credentials.
It is believed the youngest victim of the cyber-attack was 15, and the eldest 65.
The hacker reportedly gained the login details in 2011 through an online game forum. Over the years, Kim then used the information to hack into several online services such as websites, selling ringtones and cinema tickets.
He then went on to extract personal information records from these sites, including bank details which he sold to mortgage fraudsters and illegal gamblers at 20p each. Kim scooped up the profit of £235,000.
Some of the compromised data records could still be circulating around criminal gangs. The authorities have launched an investigation into tracking down the details.
