Windows systems require DLL files to understand how to use their resources, the host computer memory, and hard drive space most efficiently.ДLL files usually end with a. These could include images and a library of executable functions.ДLL files cannot be opened by end-users, they can only be opened by their associated application, which usually happens when the application starts up. What are DLL Files?ДLL files, or Dynamic Link Library files, contain the resources an application needs to run successfully.

It has been in circulation among cybercriminals since Windows 2000 launched. If applications that are automatically loaded upon startup are compromised with a tainted DLL file, cybercriminals will be granted access to the infected computer whenever it loads.ДLL hijacking is not an innovative cyberattack method. Only Microsoft operating systems are susceptible to DLL hijacks.Д«y replacing a required DLL file with an infected version and placing it within the search parameters of an application, the infected file will be called upon when the application loads, activating its malicious operations.ДЇor a DLL hijack to be successful, a victim needs to load an infected DLL file from the same directory as the targeted application.

This almost cinematic breach demonstrates the formidable potency of DLL hijacking and its ability to dismantle entire organizations with a single infected file. A simple DLL file was the catalyst to the most devastating cyberattack against the United States by nation-state hackers.
