[RedEcho](https://attack.mitre.org/groups/G1042) is a People’s Republic of China-related threat actor associated with long-running intrusions in Indian critical infrastructure entities. [RedEcho](https://attack.mitre.org/groups/G1042) overlaps with various other PRC-linked threat groups, such as [APT41](https://attack.mitre.org/groups/G0096), and is linked to [ShadowPad](https://attack.mitre.org/software/S0596) malware use through shared infrastructure.(Citation: RecordedFuture RedEcho 2021)(Citation: RecordedFuture RedEcho 2022)
