SkyCloak is a newly tracked advanced persistent threat cluster publicly identified in 2025 as one of seven newly disclosed groups active against organizations in Russia and the CIS. Available reporting places it among clusters targeting Russian government and industrial sectors, but public technical detail remains extremely limited. No confirmed public campaign analysis, malware family association, or detailed tradecraft profile has been established at high confidence. SkyCloak has been listed alongside other newly disclosed 2025 clusters such as Silent Lynx, Telemancon, Mythic Likho, NGC6061, NGC4141, and NGC5081. Despite that grouping, SkyCloak remains the least characterized of the set. Current high-confidence understanding is limited to its existence as a tracked cluster and its inclusion in activity affecting Russian and broader CIS organizations. Attribution to a specific state, country of origin, or sponsoring organization is not currently available from the supplied facts. Given the lack of corroborated public technical reporting, SkyCloak should presently be treated as an underdocumented espionage-oriented or state-aligned cluster operating in the Russia/CIS threat environment, with further details on tooling, intrusion lifecycle, and victimology not yet available at high confidence.
