![]() ![]() It is set by the system when the process is debugged. This field refers to the second byte in the Process Environment Block of the process. This API simply reads the PEB!BeingDebugged byte-flag (located at offset 2 in the PEB structure).Ĭircumventing it is as easy as setting PEB!BeingDebugged to 0. IsDebuggerPresent returns 1 if the process is being debugged, 0 otherwise. Anti-debugging and anti-tracing techniques Specific debugger detection, such as window or processes enumeration, registry scanning, etc. Note that we will talk purely about generic anti-debugging and anti-tracing techniques. The paper is aimed towards reverse-engineers and malware analysts. We'll suppose the program is analyzed under a ring3 debugger, such as OllyDbg on Windows platforms. They are used by commercial executable protectors, packers and malicious software, to prevent or slow-down the process of reverse-engineering. ![]() This paper classifies and presents several anti-debugging techniques used on Windows NT-based operating systems.Īnti-debugging techniques are ways for a program to detect if it runs under control of a debugger. ![]() Anti-debugging techniques are ways for a program to detect if it runs under control of a debugger.
