North targeted South’s cryptocurrency 10 timesUN experts say they are investigating at least 35 instances in 17 countries of North Koreans using cyberattacks to illegally raise money for weapons of mass destruction programs - and they are calling for sanctions against ships providing gasoline and diesel to the country.
Last week, The Associated Press (AP) quoted a summary of a report from the experts which said that North Korea illegally acquired as much as $2 billion from its increasingly sophisticated cyber activities against financial institutions and cryptocurrency exchanges.
The lengthier version of the report, recently seen by the AP, reveals that neighboring South Korea was hardest-hit, the victim of 10 North Korean cyberattacks, followed by India with three attacks, and Bangladesh and Chile with two each.
Thirteen countries suffered one attack - Costa Rica, Gambia, Guatemala, Kuwait, Liberia, Malaysia, Malta, Nigeria, Poland, Slovenia, South Africa, Tunisia and Vietnam, it said.
The experts said they are investigating the reported attacks as attempted violations of UN sanctions, which the panel monitors.
The report cites three main ways that North Korean cyber hackers operate. First, attacks through the Society for Worldwide Interbank Financial Telecommunication (SWIFT) system used to transfer money between banks, “with bank employee computers and infrastructure accessed to send fraudulent messages and destroy evidence.”
Second, theft of cryptocurrency “through attacks on both exchanges and users.”
Third, “mining of cryptocurrency as a source of funds for a professional branch of the military.”
The experts stressed that implementing these increasingly sophisticated attacks “is low risk and high yield,” often requiring just a laptop computer and access to the internet.
The report to the Security Council gives details on some of the North Korean cyberattacks as well as the country’s successful efforts to evade sanctions on coal exports in addition to imports of refined petroleum products and luxury items including Mercedes Benz S-600 cars.
As examples of North Korean cyberattacks, the panel said hackers in one unnamed country accessed the infrastructure managing its entire ATM system and installed malware modifying the way transactions are processed. As a result, it forced 10,000 cash distributions to individuals working for or on behalf of North Korea “across more than 20 countries in five hours.”
In Chile, the experts said, North Korean hackers demonstrated “increasing sophistication in social engineering,” by using LinkedIn to offer a job to an employee of the Chilean interbank network Redbanc, which connects the ATMs of all the country’s banks.
According to a report from one unnamed country cited by the experts, stolen funds following one cryptocurrency attack in 2018 “were transferred through at least 5,000 separate transactions and further routed to multiple countries before eventual conversion” to currency that a government has declared legal money, “making it highly difficult to track the funds.”
In South Korea, the experts said, North Korean cyber actors shifted focus in 2019 to targeting cryptocurrency exchanges, some repeatedly.
The panel said South Korea’s Bithumb, one of the largest cryptocurrency exchanges in the world, was reportedly attacked at least four times. It said the first two attacks in February 2017 and July 2017 each resulted in losses of approximately $7 million, while a June 2018 attack led to a $31 million loss and a March 2019 attack to a $20 million loss.
The panel said it also investigated instances of “cryptojacking” in which malware is used to infect a computer to illicitly use its resources to generate cryptocurrency. It said one report analyzed a piece of malware designed to mine the cryptocurrency Monero “and send any mined currency to servers located at Kim Il Sung University in Pyongyang.”
