According to a new press report published by South Korea's National Intelligence Service (NIS), North Korean hackers have stolen more than 800 billion Korean won ($620 million) worth of cryptocurrencies from decentralized finance, or DeFi, platforms this year. The agency also revealed it blocked a daily average of 1.18 million attacks perpetrated by national and international hacking organizations in November. 

However, a NIS spokesperson revealed via local news outlet Kyunghyang Shinmun that all of the $620 million stolen by North Korean hackers through DeFi exploits occurred overseas, adding: 

"In Korea, virtual asset transactions have been switched to real-name transactions and security has been strengthened, so there is no damage."
