According to Eun Young Choi, the head of China's Cryptocurrency Implementation Working Group (NCET), in addition to the millions of dollars of losses caused by the intrusion and use of DeFi hackers, there are also serious national security problems.

This is a very serious national security problem, far exceeding the fact that millions of dollars have been stolen from DeFi network hackers and single centralized system exploits.

The executive director expressed this concern at the 2022 All Sales Market Conference of Yahoo! Financial Industry yesterday, and added that data encryption crimes are now occurring in every criminal act investigated by NCET.

According to chainalysis, since January, suspect of blockchain technology have stolen as much as $3 billion of investors' cash according to 141 different types of login password system vulnerabilities, an increase of 31% over 2022. Therefore, it is estimated that 2022 will undoubtedly be the year with the largest number of hackers on the cryptocurrency network so far.

The chain analysis shows that in October alone, the use of cross chain highway bridges resulted in a loss of 718 million dollars, and a loss of 2 billion dollars in 2022.

Even so, NCET and the United States cooperated with other international federal governments to help seal up about 3.8 billion dollars of stolen cryptocurrencies this year. However, the vast majority of this amount came from a complaint in February, involving the stolen proceeds in 2016 due to suspected money launderers.

In addition, Director Choi indicated that the web3 field has been improved, and the company will realize that adopting the most basic risk reduction preventive measures and formulating a strong compliance management plan is the best defense. In relevant news, BitKeep Swap's multi chain wallet was leaked today, causing losses of more than $1 million.
