"The methods used show gaping holes in KYC processes

Tian and Li were easily able to game the Know-Your-Customer (KYC) processes implemented by exchanges. The pair uploaded images to one exchange purportedly showing a South Korean man and a German man holding up government-issued IDs. The images’ metadata reveals that not only were the pictures doctored, but actually featured different heads photoshopped on the same body.

Another exchange with better security flagged images submitted by the pair as having been doctored and requested a video conference to confirm the account holders’ identities. This ended that particular KYC attempt.

In a press release announcing the charges against the Chinese nationals, General Benczkowski of the U.S. Department of Justice (DoJ) asserted that the DOJ “will pierce the veil of anonymity provided by cryptocurrencies to hold criminals accountable, no matter where they are located.”

Last month, a report concluded that North Korean internet usage had trebled over three years amid increasing cryptocurrency adoption by the regime."
