SEOUL -- North Korea is firing a fusillade of ransomware attacks outside its borders, turning to cryptocurrency extortion for easy money as tough international sanctions bite.
Pyongyang has increasingly targeted small and midsize businesses in South Korea with ransomware since 2018, apparently to exploit weak security and the common language, according to a source with knowledge of the North's illegal financing activities. The South's National Intelligence Service reports 1.58 million attempted cyberattacks a day here.
