North Korean hackers working for the government stole record-breaking virtual assets last year estimated to be worth between $630 million and more than $1 billion, U.N. experts said in a new report.
The panel of experts said in the wide-ranging report seen Tuesday by The Associated Press that the hackers used increasingly sophisticated techniques to gain access to digital networks involved in cyberfinance, and to steal information that could be useful in North Korea's nuclear and ballistic missile programs from governments, individuals and companies.
