Context
DocSwap is an Android malware first identified in 2025, and attributed to Kimsuky. DocSwap’s name is a combination of its Korean name “문서열람 인증 앱” (Document Viewing Authentication App) and a phishing page masquerading as CoinSwap at the C2 address. Based on DocSwap’s name and Korean-language strings, DocSwap potentially targets mobile device users in South Korea. Several variants of DocSwap exist; one of the latest samples indicates that the adversary added a native decryption function that decrypts an internal APK.
