As the Lunar New Year of 2023 approached, South Korea experienced an unexpected storm in the digital realm. The nation's cyber landscape was jolted by a series of attacks orchestrated by a hacker group known as "Dawn Cavalry" (also known as "Xiaoqiying", "Genesis Day", "Teng Snake"). This assault thrust a dozen research and academic institutions into a state of digital disarray.
A Coordinated Cyber Offensive
Dawn Cavalry, allegedly a Chinese hacker group, executed a well-coordinated cyber offensive targeting the websites of twelve South Korean institutions. According to a report from Gnews (gnews.org), the Korea Internet & Security Agency (KISA) identified the affected research and academic institutions, which include:
Korean Research Institute for Construction Policy
Korean Archaeological Society
Woorimal Academic Society
Korean Academy of Basic Medicine & Health Science
Association for Studies in Parents and Guardians
Research Institute for Early Childhood Education
Korean Lesson Study Group for Social Studies
Korean East-West Mind Science Association
Korean Cleft Lip and Palate Association
Korean Association for the Education and Rehabilitation of the Blind and Visually Impaired
Jeju Education & Science Research Institute
Korean Society for the Study of Educational Principles
KISA reports that all of the institutions suffered website defacement attacks, and the group claims to have stolen a total of 54 GB of data during these attacks. These attacks were not only disruptive but showcased the group’s capability to infiltrate and commandeer critical data networks. Their bold proclamation of invasion was broadcast ominously across compromised websites, adorned with their logo and a declaration in both Chinese and English.
Vulnerabilities and Consequences
A glaring weakness exploited by Dawn Cavalry was the lack of encrypted data transmissions between users and these institutions' web servers. This vulnerability not only facilitated easy access for the hackers but also heightened the risk of sensitive information being intercepted. KISA, the country’s cyber-safety agency, was embroiled in a rigorous investigation to piece together the attack's intricacies, yet progress remained hindered by the holiday’s disruption.
Motives and Plans: Beyond a Cyber Ransack
The motivations behind these digital incursions were multifaceted. Dawn Cavalry hinted at using South Korea as a "training ground" for its members, a declaration that underscored both their audacity and intent for continued cyber operations. Their grievances, seemingly as varied as their cyber targets, included discontent with Korean streaming stars—a testament to how digital influence could extend into realms of unexpected consequence.
Despite KISA's efforts, identifying the group's origins and backers remained challenging. Speculations about their links to mainland China arose from the use of simplified Chinese in their communications, but definitive attribution remained elusive.
The Road Ahead
In today's increasingly politically heated climate, organizations can find themselves becoming targets of cyber crime simply for being in a country or region considered hostile by ideologically-motivated threat actors. Such is the case with Dawn Cavalry, which, despite having no confirmed support from the Chinese government, have specifically targeted NATO countries and those with histories of Chinese tensions.
Staying One Step Ahead
As South Korea grappled with the immediate impact of these breaches, there was an urgent call for enhanced cybersecurity measures. Institutions, especially those dealing with sensitive data, needed to re-evaluate their security protocols and fortify their digital defenses against future assaults.
