A North Korean defector has made some terrifying claims about the regime's hacking prowess, saying it has the ability to remotely attack the infrastructure of us evil Westerners to such an extent that the resulting collapse in our delicate society could lead to mass deaths.
The worry has been caused by Prof Kim Heung-Kwang, who says North Korea has a virtual army of around 6,000 cyber-warriors ready to strike. Prof Kim taught computer science in the country until escaping in 2004, and now thinks some of his former students have gone on to power the country's hacking division known as Bureau 121.
Kim told the BBC the threat is definitely on the real side of theoretical, explaining: "The reason North Korea has been harassing other countries is to demonstrate that North Korea has cyber war capacity. Their cyber-attacks could have similar impacts as military attacks, killing people and destroying cities."
Kim's most worrying claim is that a Stuxnet clone has been built by the regime's hackers, with the autonomous malware "designed to destroy" our infrastructure apparently a viable threat. So if one of your street lights refuses to turn off in the day time tomorrow, it could be those bloody North Korean hackers running wild on your council's intranet. [BBC]
