MEGAsync staged in non-standard path for exfiltration
Detects the execution of MEGAsync binaries (MEGAsync.exe, MEGAupdater.exe, or MEGAsyncSetup64.exe) from suspicious locations typically used for staging (Temp, Downloads, Public folders), or the creation of MEGAsync configuration and state cache files in the local AppData directory. This pattern is consistent with an adversary setting up a legitimate cloud storage client for data exfiltration.
