Members of a criminal organization suspected of spreading malicious ransomware "CLOP" have been caught in Ukraine via a coordinated joint investigation involving Ukrainian police, the FBI and Interpol.
South Korea's National Police Agency said Friday the joint investigation busted four people on charges for hacking, blackmail and concealment of crime proceeds.
Procedures were launched to bring two of them to South Korea.
Three out of the four are Ukrainian and one is currently an unidentified foreign national.
Clop ransomware is known to have been distributed in February 2019 to four South Korean universities and companies and paralyzed some 720 computer systems.
As a result, the program has allegedly extorted a total of 65 Bitcoins valued at around three.eight million U.S. dollars.
South Korean police said information on the suspects' methods and infiltration had been shared with 20 countries soon after the hacking incidents and found the suspects had converted the extorted Bitcoin into cash at overseas exchanges.
The Korean police agency said it's slated to present its latest findings at the upcoming "International Symposium on Cybercrime Response" an online event scheduled for Monday.
