Norway’s unit for fighting economic and environmental crimes, Okokrim, has seized 60 million Kroner ($5.9 million) in cryptocurrency linked to the $600 million Axie Infinity hack that happened in March 2022.

The FBI identified the North Korean Lazarus Group as the group behind the hack, and with the help of Chainalysis, the US government was able to recover $30 million in stolen cryptocurrencies in September 2022.

North Korea has been a major contributor to cryptocurrency hacking, according to a recent Chainalysis report, which revealed that hackers from the country looted $1.7 billion worth of cryptocurrencies.

The Lazarus Group is a notorious cybercrime group believed to be based in North Korea, although the North Korean government has denied any involvement.
