【Slow Fog CISO: Suspected North Korean hacker group Kimsuky APT member suffers data leak, exposing internal tools and operational details】Golden Finance reports that Slow Fog's Chief Information Security Officer 23pds tweeted, "A member of the suspected North Korean hacker group Kimsuky APT has suffered a significant data leak, exposing hundreds of GB of internal documents and tools. The intrusion likely occurred in early June 2025, revealing the organization's complex backdoors, phishing frameworks, and reconnaissance operations. Analysis of the leaked files indicates that the internal dump originated from two compromised systems belonging to an operator codenamed 'KIM' from Kimsuky. One is a Linux development workstation running Deepin 20.9; the other is a public-facing VPS used for spear-phishing activities."
