-Sandbox Detection
-=================
+# Sandbox Detection
+
 Detects whether the malware instance is being executed inside an instrumented sandbox environment (e.g., Cuckoo Sandbox). If so, conditional execution selects a benign execution path.
 
 The related **Virtualization/Sandbox Evasion ([T1497](https://attack.mitre.org/techniques/T1497/), [T1633](https://attack.mitre.org/techniques/T1633/))** ATT&CK techniques were defined subsequent to this MBC behavior.
