Aliases: Earth Kasha, MirrorFace
[MirrorFace](https://attack.mitre.org/groups/G1054) is a People's Republic of China (PRC)-aligned cyberespionage actor believed to be a subgroup under the [menuPass](https://attack.mitre.org/groups/G0045) umbrella based on targeting, tools, and infrastructure overlaps. [MirrorFace](https://attack.mitre.org/groups/G1054) has been active since at least 2019, at first exclusively targeting Japanese organizations across the media, defense, diplomatic, financial, manufacturing, and academic sectors. Subsequent [MirrorFace](https://attack.mitre.org/groups/G1054) operations included targets in Central Europe and featured use of [LODEINFO](https://attack.mitre.org/software/S9020), [HiddenFace](https://attack.mitre.org/software/S9023), and [UPPERCUT](https://attack.mitre.org/software/S0275) malware.(Citation: Kaspersky LODEINFO OCT 2022)(Citation: Kaspersky LODEINFO Part II OCT 2022)(Citation: ESET MirrorFace DEC 2022)(Citation: JPCERT MirrorFace JUL 2024)(Citation: Trend Micro Earth Kasha NOV 2024)(Citation: Trend Micro Earth Kasha Updates APR 2025)
