Get Ahead with Thick Client Pen Testing Tips from Redfox Security

DLL hijacking is a common vulnerability that affects insecure thick client or desktop applications. This vulnerability poses significant risks as malicious actors can exploit it to gain unauthorized access or execute arbitrary code. In this video, we will explore DLL hijacking, identifying and exploiting these vulnerabilities.

DLL (Dynamic Link Library) files hold multiple codes and procedures shared across programs. When a program needs a function, it calls the DLL file containing it. However, if the program doesn't specify the DLL file's exact location, it can be vulnerable to DLL hijacking. Attackers exploit this by placing a malicious DLL in a location controlled by them, causing the application to load it instead of the legitimate file.

To identify DLL hijacking vulnerabilities, look for unexpected error messages, abnormal behavior, or crashes when certain functions are called. These signs can indicate potential DLL hijacking, which security professionals can analyze and mitigate.

Exploiting DLL hijacking involves replacing a legitimate DLL with a malicious one and tricking the application into loading it. Techniques include manipulating the search order or placing the malicious DLL in a prioritized directory. Once loaded, the attacker can execute their code, potentially compromising the system.

Stay tuned until the end of the video for a comprehensive lesson on DLL hijacking, a valuable addition to your methodology or TTPs for testing desktop applications for vulnerabilities.
