![]() (For a larger resolution of this diagram visit this link) Azorult LoaderĪzorult loader is a classic “Trojan Horse” that contains several components including the Azorult malware itself and additional embedded files to enable remote access and data collection. In this blog, the Splunk Threat Research Team will do a deep dive analysis on “Azorult loader” and its several components to understand tactics and techniques that may help SOC analysts and blue teamers defend against these types of threats. This software restriction policy may be abused by adversaries, like the “Azorult loader,” a payload that imports its own AppLocker policy to deny the execution of several antivirus components as part of its defense evasion. This feature advances the functionality of software restriction policies and enables administrators to create rules to allow or deny applications from running based on their unique identities (e.g., files) and to specify which users or groups can run those applications.ĪppLocker has the ability to control the execution of executables (“.exe” and “.com”), scripts (“.js”, “ps1”, “vbs”, “.cmd” and “.bat”), windows installer (“.msi, “.mst”, “.msp”), dll modules, packaged apps, and app installer. Even so, it can prove to be useful in keeping you focused.Microsoft continues to develop, update and improve features to monitor and prevent the execution of malicious code on the Windows opearting system. However, it still lacks a few features, with no password protection method or the possibility to work over LAN or multiple accounts. To sum it up, AppLocker gets the job done flawlessly and managed to lock down all applications we threw at it. You don't have to write down the full path, just the name and EXE extension, but you must pay attention and provide the exact name, otherwise AppLocker is not able to locate the specified item to block. ![]() Unfortunately, there is no included explorer to navigate to the target executable file and have it selected. The configurations panel displays a list of applications that can be blocked, with a field for a name and one for the executable file. In addition, you can handle and populate the existing list with applications you consider more suitable than the ones already suggested. The reverse process can be done for applications individually, or with the help of the “Unlock All” button. It's enough tick the check box next to its corresponding element and hit the “Save” button in order for restrictions to be applied. By default, you can select from a decent list that includes Notepad, MS Paint, Internet Explorer, as well as all tools included in the Microsoft Office suite. Choose from a list of presetsĪs you figured out, the core function is to completely restrict applications you choose. All features are stored in a compact and intuitive interface and even though there is no included help manual it poses no accommodation problems whatsoever. With the setup process taking only several settings and requiring minimum attention, you are free to launch the application. One such utility is AppLocker and promises to do exactly what the name suggests. However, with the proper applications you can lock down certain Windows features or apps so you can better focus on the task at hand. While offering a powerful environment for nearly all domains of activity, the computer can also keep you distracted while working.
