Dragon Breath

On April 7, 2026, a new sample of the long-running malicious sims-4-updater.exe campaign surfaced on MalwareBazaar... The implant is a custom-virtualized PE64 backdoor whose runtime artifacts (mutex Global\DHGGlobalMutex, registry keys HKCU\offlinekey\open / HKCU\offlinekey\clipboard) match documented APT-Q-27 / GoldenEyeDog / Dragon Breath tooling.
