DocSwap - S9005 (3dbef387-12df-4547-9dd3-075c7ffec9e3)
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.(Citation: EnkiWhiteHat_KimsukyDOCSWAP_Dec2025)(Citation: S2W_DocSwap_Mar2025)
