Hackers could hack hot wallets more frequently than cold wallets. In cold wallets, users stored private keys offline on external hard drives and USBs. Upbit was subjected to a $50 million attack in 2019. However, since then Upbit has not experienced a single security breach, according to Yonhap. A Dunamu spokesperson:

“After the hacking incident in 2019, we took various measures to prevent repeated incidents like business by distributing our hot wallets and so far there has not been a single cyber breach. “

“The Ministry of Science and Technology should conduct large-scale whitening trials and examine information security conditions in preparation for cyber attacks on virtual asset exchanges where frequent hacking.” Also, Seong-Jung added:

“The role of the Ministry of Science and Technology in administration and supervision is unclear. “
