Sinbad was a key money laundering tool used by Lazarus Group — a sanctioned, state-sponsored group of cyber hackers of the Democratic People’s Republic of North Korea (DPRK). Cryptocurrency stolen by DPRK sponsored groups has been used to ultimately fund North Korea’s weapons programs. Sanctioned by OFAC in 2019, Lazarus Group has been implicated in stealing over $3 billion worth of cryptocurrency. Cryptocurrency mixing services, while potentially useful for legitimate privacy purposes, have become a prime instrument in the toolkit of cybercriminals, including North Korean-linked attackers.
