Exploring debugger detection

For malware authors to keep their operations going without being interrupted by antivirus products or any takedown operations, they have to fight back and equip their tools with various anti-reverse engineering techniques. Debuggers are the most common tools that malware analysts use to dissect malware and reveal its functionality. Therefore, malware authors implement various anti-debugging tricks to complicate the analysis and keep their functionality and configuration details (mainly Command & Control servers or C&Cs) hidden.

Using PEB information

Windows provides lots of ways to identify the presence of a debugger; many of them rely on the information stored in the Process Environment Block (PEB). For example, one of its fields located at offset 2 and called BeingDebugged is set to True when the process is running under a debugger. To access this flag, malware can execute the following instructions:

mov  eax, dword ptr fs:...
