A DLL Loader is a program or software component responsible for loading Dynamic Link Libraries (DLLs) into a computer's memory for execution. In legitimate contexts, DLL Loaders are essential for running shared code and resources in Windows applications. However, cybercriminals often exploit DLL Loaders to inject malicious DLLs into processes, enabling stealthy execution of malware, privilege escalation, or evasion of security controls. Attackers may use custom DLL Loaders in phishing campaigns, fileless attacks, or to bypass application whitelisting. Detecting unauthorized DLL loading is crucial for preventing malware infections and maintaining system integrity.
