[LunarWeb](https://attack.mitre.org/software/S1141) is a backdoor that has been used by [Turla](https://attack.mitre.org/groups/G0010) since at least 2020 including in a compromise of a European ministry of foreign affairs (MFA) together with [LunarLoader](https://attack.mitre.org/software/S1143) and [LunarMail](https://attack.mitre.org/software/S1142). [LunarWeb](https://attack.mitre.org/software/S1141) has only been observed deployed against servers and can use [Steganography](https://attack.mitre.org/techniques/T1001/002) to obfuscate command and control.(Citation: ESET Turla Lunar toolset May 2024)
