GoldMax is a second-stage C2 backdoor written in Go with Windows and Linux variants that are nearly identical in functionality. GoldMax was discovered in early 2021 during the investigation into the SolarWinds Compromise, and has likely been used by APT29 since at least mid-2019. GoldMax uses multiple defense evasion techniques, including avoiding virtualization execution and masking malicious traffic.
