South Korea accuses North of cyberattacks, announces sanctions

North Korea has tried to hack into email accounts of South Korean railway workers in an attempt to attack the transport system's control system, South Korea's spy agency said on Tuesday.

South Korea has been on heightened alert against the threat of cyberattacks by North Korea after it conducted a nuclear test in January and a long-range rocket launch last month, triggering new UN sanctions.

South Korea had previously blamed the North for cyberattacks against its nuclear power operator. North Korea denied that.

South Korea's National Intelligence Service (NIS) said in a statement it had interrupted the hacking attempt against the railway workers and closed off their email accounts.

The agency issued the statement after an emergency meeting with other government agencies on the threat of cyberattacks by the North. The agency detected hacking attempts by the North against workers for two regional railway networks this year, the spy agency said.

"The move was a step to prepare for cyberterror against the railway transport control system," the agency said.

It did not elaborate on what it thought North Korea's specific objective was in hacking into the system. An agency official reached by telephone declined to comment.

Additional sanctions announced

North Korea has been working for years to develop the ability to disrupt or destroy computer systems that control public services such as telecommunications and other utilities, according to a defector from the North.

The United States accused North Korea of a cyberattack against Sony Pictures in 2014 that led to the studio cancelling the release of a comedy based on the fictional assassination of the country's leader, Kim Jong-un. North Korea denied the accusation.

In 2013, South Korea blamed the North for crippling cyberattacks that froze the computer systems of its banks and broadcasters for days.

New fears of attacks on South Korea's computer systems came as South Korean and U.S. troops conducted large-scale military exercises which North Korea denounced as "nuclear war moves" and threatened to respond with an all-out military offensive.

Also Tuesday, South Korea said it would independently impose new sanctions against 40 individuals and 30
entities for Pyongyang's weapons programme and ban any vessels that had stopped at North Korean ports in the past 180 days.

The sanctioned individuals include a Singaporean and Taiwanese nationals.

South Korea would also discontinue participation in a pilot project that brought Russian coal to South Korea through a North Korean port, Rajin, a foreign ministry told reporters in a joint briefing with other government agencies.
