Cybersecurity experts and enthusiasts around the world are abuzz with the news of a devastating ransomware attack that has disrupted operations at one of South Korea's most prominent conglomerates, Kyowon. In this article, we will delve into the details of the attack, its impact on the company and its stakeholders, and explore the implications of such an incident for the global cybersecurity landscape.
The attack, which is believed to have occurred in early January 2026, has left the Kyowon conglomerate reeling, with several of its core subsidiaries, including Kyowon Kumon, Wiz, Life, Tour, Property, Healthcare, and Start One, affected by the cyberattack. According to reports filed with the Korea Internet & Security Agency (KISA), the attack involved an external server that was exposed to the internet, which was used by the attacker to infiltrate the internal system, leading to a ransomware infection that spread throughout the subsidiaries.
The attacker exploited an open external port to gain access to Kyowon's network, spreading laterally across subsidiaries and disrupting major services and databases. Extortion attempts followed the ransomware infection, although authorities have not yet been notified. According to estimates by the Korea Joongang Daily, around 9.6 million accounts may have been impacted by the cyberattack.
The Kyowon breach is part of a larger wave of major cyberattacks on South Korean companies that have exposed sensitive data in recent times. Other notable incidents include Coupang, which affected 33.7 million customers, and Korean Air, which saw its staff information compromised. SK Telecom has also revealed a malware breach dating back to 2022 that exposed the data of 27 million subscribers.
In response to the attack, Kyowon Group confirmed signs of an external cyber intrusion, believed to be ransomware, on Saturday, January 10. The company immediately reported the incident to KISA and relevant investigative authorities, and is working with external cybersecurity experts and authorities to restore systems and assess the breach.
"At around 8 a.m. on January 10, we detected suspicious signs of an external cyber intrusion, believed to be ransomware. Immediately after recognizing the incident, we reported the circumstances to KISA and relevant investigative authorities, and we are working with external cybersecurity experts to precisely determine the cause and extent of the damage," said a statement released by Kyowon Group.
The company added that it is still checking whether any personal information has been leaked. If a data breach is confirmed, it will promptly and transparently notify customers and take all necessary protective measures in accordance with relevant laws and procedures.
In light of this incident, cybersecurity experts are warning companies to prioritize their cybersecurity posture, particularly when it comes to protecting sensitive data and systems from external threats. The attack highlights the importance of robust cybersecurity controls, including firewalls, intrusion detection systems, and regular software updates.
Moreover, the incident underscores the need for greater collaboration between companies, regulatory agencies, and law enforcement in responding to cyberattacks. By sharing information and best practices, these stakeholders can better mitigate the impact of such incidents and prevent future breaches.
As the world grapples with the increasing complexity and sophistication of cyber threats, it is essential that we prioritize cybersecurity awareness and education, particularly for small and medium-sized enterprises (SMEs). SMEs are often vulnerable to cyberattacks due to their limited resources and expertise.
In conclusion, the ransomware attack on Kyowon conglomerate serves as a stark reminder of the devastating consequences of cyber breaches. As we move forward, it is crucial that companies prioritize their cybersecurity posture, collaborate with regulatory agencies and law enforcement, and invest in cybersecurity awareness and education programs.
