S2W (CEO Suh Sangduk), a big data-based artificial intelligence (AI) security company, announced that it participated as a presenter at the global cybersecurity conference 'Virus Bulletin 2025 (VB2025)' held in Berlin, Germany from September 24th to 26th.
S2W has been selected to present at the VB Conference for five consecutive years since 2021, demonstrating its technical expertise and global competitiveness in the cybersecurity field. Drawing on years of accumulated threat intelligence analysis experience, the company has long-term tracked and analyzed major cyber threat groups based in North Korea, China, and Russia. Building on this experience, the company published two research findings this year.
The first presentation was the results of an analysis of the mobile malware "DocSwap," conducted by Kim Hyung-jun, a researcher at the S2W Threat Intelligence Center. DocSwap is an advanced malware that disguises itself as a security application and infiltrates user devices, capable of executing up to 57 commands. It garnered significant attention for its connection to the "Kimsuky" group, a known North Korean cyberattack organization.
The second presentation, jointly conducted by Kim Ji-ho, Senior Researcher, and Kim Jae-gi, Director of the Threat Intelligence Center, focused on ScarCruft (APT37), the group's recent cyberattack campaign. The presentation identified new attack tools, including backdoors leveraging the PubNub API, Rust-based malware, and custom ransomware. It also revealed the group's strategy expanding beyond its previous focus on intelligence to include financial gain.
The VB Conference, a global cybersecurity technology event launched in 1989, rigorously selects presenters based on technical depth and practical contributions. Consequently, presentations at this conference are recognized as credible and influential research within the global security industry.
Suh Sangduk, CEO of S2W, said, “The VB2025 presentation is not just about participating in an event; it is the international validation of S2W’s threat analysis capabilities and expertise.” He added, “In particular, we will continue to contribute to the global security ecosystem based on our independent data analysis experience on North Korea, China, and Russia-based threat groups.”
