South Korea’s financial industry hit by fresh wave of cyberattacks

South Korea's financial landscape faces fresh cyberattacks, underscoring the escalating threat of AI-driven hacking in the region. Brokerages Daishin Securities and Mirae Asset Global Investments, along with crypto exchange Bithumb, have fallen victim to the latest breach. This marks a month since a series of cyberattacks targeting South Korean financial entities, raising concerns over systemic vulnerabilities.

Security researchers associate the September wave of attacks on South Korea with a suspected China-based hacker who utilized the AI penetration testing tool, Artex, though authorities are still probing the origins of the most recent intrusions.

Daishin Securities disclosed a cyberattack exposing personal data of 38,490 customers, including names, email addresses, and mobile phone numbers. The firm has notified affected individuals, is collaborating with authorities, and pledges to compensate for any losses in line with legal requirements. Mirae Asset Global Investments and Bithumb reported separate cybersecurity incidents on Wednesday, though neither has confirmed the theft of customer data.

South Korea's financial watchdog has urged for enhanced cybersecurity protocols in the wake of a series of attacks on financial institutions and government agencies. The nation also intends to conduct security audits on numerous private sector IT systems. Recently, Japan reported a cybersecurity incident involving GMO Internet, following a string of attacks on its financial entities.

The wave of cyberattacks across Asia highlights the growing cybersecurity challenges in the region, often stemming from years of inadequate cybersecurity measures; however, investigators have yet to establish a direct link between the incidents. South Korea's Financial Services Commission (FSC), Daishin Securities, Bithumb, and Mirae Asset Global Investments have not yet provided comment on the matter.
