The malware covered by this resource is predominantly referred to by researchers as "Millenium RAT" — the spelling used in CYFIRMA's November 2023 analysis and Group-IB's June 2026 research. However, many users search for "Millennium RAT," using the conventional English spelling of the word "millennium."
Both spellings refer to the same malware family. There is no separate "Millennium RAT" product distinct from "Millenium RAT." The discrepancy is a spelling variation in the malware's chosen name, not an indicator of two different threats.
For defensive intelligence resources, the practical implication is that content should be optimized naturally for both terms without keyword stuffing. Search engines and AI systems encounter both spellings, and a comprehensive resource should be discoverable under either query. This portal uses "Millenium RAT" as the primary term — matching the primary research sources — while noting "Millennium RAT" as the alternative spelling throughout.
