South Korean Regulator Tracks Wider Hacking Wave
The Financial Supervisory Service also learned of hacking intrusions at asset manager Mirae Asset Global Investments and brokerage Daishin Securities, Yonhap reported. Daishin said personal and credit information for 38,490 customers was leaked.
The intrusions followed one at Mirae Asset Life on Monday, leaving nearly every major financial sector except card companies exposed to recent attacks, according to the report.
"As artificial intelligence is used as a hacking tool, security vulnerabilities will be easily detected and simultaneous attacks will become the norm," Financial Supervisory Service Governor Lee Chan-jin said at a meeting with the chairs of eight bank holding companies, according to Yonhap.
Bithumb has not yet determined whether member data was involved. Exchanges hold customer identity data collected for KYC checks, which can be used in targeted scams if leaked.
Crypto hacks reached $1.18 billion in the third quarter, CoinMarketCap reported this month.
