According to TechFlow, a United Nations report said that North Korean hackers infiltrated the encryption industry by forging job applicants' identities, and fake recruitment programs alone made North Korea earn up to $600 million a year. About 4,000 North Koreans tried to enter the Western technology industry, including the encryption industry, by concealing their identities.

North Korean hackers have stolen $3 billion worth of crypto assets in 58 cyber thefts over the past seven years, and experts warn that the trend may just be beginning, bringing new security challenges to the crypto industry.

Taylor Monahan, chief security researcher at MetaMask, pointed out that North Korea generates income through illegal sales of resources, IT work, manual labor and hacking activities. With the launch of Bitcoin ETF, Wall Street has regarded cryptocurrency as an asset class, and the demand for recruitment in the encryption industry has surged, but the influx of fake job seekers has made recruitment more difficult.
