These could include images and a library of executable functions.ĭLL 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?ĭLL 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.ĭLL hijacking is not an innovative cyberattack method. Only Microsoft operating systems are susceptible to DLL hijacks.īy 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.įor a DLL hijack to be successful, a victim needs to load an infected DLL file from the same directory as the targeted application. What is DLL Hijacking?ĭLL hijacking is a method of injecting malicious code into an application by exploiting the way some Windows applications search and load Dynamic Link Libraries (DLL). This almost cinematic breach demonstrates the formidable potency of DLL hijacking and its ability to dismantle entire organizations with a single infected file. This will track any newly created process on the system, meaning that if you launch an EXE installer and it installs an MSI, it will first need to create the MSI operation which will handle the Windows Installer execution.A simple DLL file was the catalyst to the most devastating cyberattack against the United States by nation-state hackers. Under the drop down menu, hover the Filter > Filter, go to Display entries matching this condition and select Operation is Process Create. We already covered this scenario in the MSI Packaging ebook - Helpful tools chapter, but let’s go quickly through the steps: You can filter anything from Architecture, Authentication ID, Category, Command Line, Company, Completion time, Date & Time to Version.Īnother example where filtering is important is when we want to find out if a particular EXE contains an MSI that is extracted and executed during the installation. By filtering operations, you can easily detect your issues on your system/application. Cool right?įiltering operations is one of the most important and powerful aspects of Procmon. This will ensure that only the Explorer.exe will appear in the capture, and with the registry operations filter, you will now see only what Explorer.exe operations are happening in the registry.
