Seoul says £962m in digital assets stolen by North Korean hackers

North Korean hackers have stolen an estimated 1.5 trillion won (£962 million) in cryptocurrency and other virtual assets in the past five years, more than half of it this year alone, South Korea’s spy agency has said.

Experts and officials say North Korea has turned to crypto hacking and other illicit cyber activities as a source of badly needed foreign currency to support its fragile economy and fund its nuclear programme following harsh UN sanctions and the Covid-19 pandemic.

South Korea’s main spy agency, the National Intelligence Service (NIS), said North Korea’s capacity to steal digital assets is considered among the best in the world because of the country’s focus on cybercrimes since UN economic sanctions were toughened in 2017 in response to its nuclear and missile tests.

The UN sanctions imposed in 2016-17 ban key North Korean exports such as coal, textiles and seafood, and also led member states to repatriate North Korean overseas workers.

Its economy suffered further setbacks after it imposed some of the world’s most draconian restrictions against the pandemic.

The NIS said state-sponsored North Korean hackers are estimated to have stolen 1.5 trillion won (£962 million) in virtual assets around the world since 2017, including about 800 billion won (£513 million) this year alone. It said more than 100 billion won (£64 million) of the total came from South Korea.

It said North Korean hackers are expected to carry out more cyberattacks next year to steal advanced South Korean technologies and confidential information on South Korean foreign policy and national security.

Earlier this month, senior diplomats from the United States, South Korea and Japan agreed to increase efforts to curb illegal North Korean cyber activities.

In February, a panel of UN experts said North Korea is continuing to steal hundreds of millions of dollars from financial institutions and cryptocurrency firms and exchanges.

Despite its economic difficulties, North Korea has carried out a record number or missile tests this year in what some experts say is an attempt to modernise its arsenal and boost its leverage in future negotiations with its rivals to win sanctions relief and other concessions.
