Load Injector.exe __FULL__



This startup command is written to the HKCU\...\Run key. It may only have 260 characters (MAX_PATH). Powershell.exe loads Injector.exe from the registry and executes it in memory. Injector.exe isrequired to be written in C#! Because of the MAX_PATH restriction, there is only room to perform a simple Assembly.Load().EntryPoint.Invoke() here.




Load Injector.exe



The injector then proceeds to load the actual Payload.exe from its own executable resources. The payload is then injected using the process hollowing technique (RunPE). This injection techniqueworks by creating a process of a legitimate Windows binary (e.g. svchost.exe). The process is created in a suspended state, after which its process memory is unmapped and replaced with the payloadfile. The thread context is set continue running at the entry point of the payload and then the main thread is resumed.


As a result, a new process (C:\Windows\System32\svchost.exe) is visible in TaskMgr, but it's actually Payload.exe. This process cannot be distinguished from legitimate instances ofthe same file without significant effort. Most 32-bit Windows binaries can be used for process hollowing of 32-bit executables.


The first malicious IronPython scripts of the tool we describe here were discovered last year by a security researcher from FireEye. At the beginning of this year, another security researcher from Dragos pointed out some new scripts of the same threat actor uploaded to VirusTotal from two different submitters. We found that one of the submitters also uploaded two other samples, which are most likely embedded payloads of one of the IronPython scripts. These samples helped us to understand how this tool works, what malware it loads and which threat actor uses it.


IronNetInjector is made of an IronPython script that contains a .NET injector and one or more payloads. The payloads can be also .NET assemblies (x86/64) or native PEs (x86/64). When an IronPython script is run, the .NET injector gets loaded, which in turn injects the payload(s) into its own or a remote process.


Both versions are full-blown PE injection tools able to load a native x86/64 payload reflectively into a remote process. This is accomplished via unmanaged functions and the use of PeNet, a publicly available PE parser library written in C#. The decompiled code is self-explanatory as meaningful function, method and variable names are used throughout the code. Additionally, log and error messages are being used extensively.


The same submitters who uploaded the IronPython scripts also submitted other files which are directly related to IronNetInjector. Based on the file sizes and the file sizes of the embedded payloads in the IronPython scripts, we can make some assumptions about what the payloads likely are.


The following table shows the IronPython scripts categorized by the different VirusTotal submitters. It also shows which other samples uploaded by the same submitter or the other submitters are connected and gives the assumed embedded malware:


When an IronPython script is run, it is loaded into the IronPython interpreter. In the IronPython script, the embedded .NET injector (SHA256: a56f69726a237455bac4c9ac7a20398ba1f50d2895e5b0a8ac7f1cdb288c32cc) and ComRAT DLL payload (SHA256: a62e1a866bc248398b6abe48fdb44f482f91d19ccd52d9447cda9bc074617d56) get decoded and decrypted. This is done with the Python Base64 module and the RijndaelManaged class from the C# cryptography namespace. The decryption key is passed as an argument to the IronPython script. The Rijndael initialization vector (IV) is stored in the script. Next, the .NET injector gets loaded into the IronPython process with the help of the Assembly.Load() method of the C# Reflection namespace. That's possible because IronPython itself is a .NET assembly and thus its process already contains all the .NET runtime libraries.


After the injector assembly is loaded, the ID of the process where the ComRAT DLL gets injected is retrieved. In this case, the explorer.exe was chosen. This routine to get the PID slightly differs in the IronPython scripts we found. While one script uses the C# method GetProcessesByName() to get the PID, the other scripts run the Windows tool tasklist.exe with the help of the Python os.popen() function. The output is then parsed to the targeted process ID with the help of tasklist filters. Also, some scripts filter the PID based on a Windows service name. When the PID is found, an instance of the injector assembly is created and the ComRAT payload bytes and PID are passed.


Finally, the injector's public methods Invoke() and InvokeVoid() get called. In the latter, the exported function name VFEP of the ComRAT payload gets passed. From this point on, the .NET injector takes control over the further execution.


These methods are used pairwise. The method InjectAssembly is used to inject a .NET assembly into a native process (or its own) and InvokeAssemblyMethod to call any chosen method of the injected assembly. The method Invoke is used to inject a native PE into a remote process and InvokeVoid to call any exported function of the injected payload.


Depending on the number of arguments passed to DefaultSerializer on creation time, the payload is either loaded into its own process or a remote one. In case only the payload bytes are passed, it gets loaded into its own process space. The other options are to also pass the ID or handle of the remote process the payload gets injected to.


Don't forget after the base install you must also install the patches to match your LoadRunner\Performance Center servers. If you are using Performance Center you should install the patches before you add the load generator to the list of available generators.


After the base and patch are installed you can then add the load generator to Lab Management for use with PC projects but make sure that you are selecting stand alone load generator as the type because you will get an error trying to add it as a host.


Load Injector supports FIX (all versions), ITCH, LSE Native, SOLA SAIL & HSVF, HTTP, SOAP, and various binary trading-system protocols. The tool's architecture is flexible and allows adding other protocols. Load Injector is an open-cycle load generator capable of supporting both model and measurement approaches of performance testing.


The growing volume of orders generated by HFT (high-frequency trading) systems has posed a challenge of conducting exchange and brokerage systems testing in production-like environments. Specialized testing tools are used to ensure quality of high load trading systems with high availability. The main requirement for such tools is that they should be capable of creating realistic, high loads using limited hardware infrastructure. This article describes a load injection tool developed for testing automated trading systems and an approach that ensures high performance.


New Super Ultimate Injector 3DS (also known as NSUI) is an application that allows you to inject Nes, Snes, GameBoy, GameBoy Colour, GameBoy Advance, Mega Drive, Game Gear and TurbiGrafx 16 roms in to the 3DS, allowing roms of games from these popular classic consoles to be loaded from the 3DS home screen.


It takes the type of hook to be installed (idHook), the pointer to the procedure (lpfn), the handle to the DLL with the procedure (hMod), and finally the tread id to associate the hook to (dwThreadId). To get the pointer to the procedure we first need to load the DLL using the LoadLibrary method. This loads it into the address space of our exe. Then GetProcessAddress we are able to locate the address to the method that we want to use. Finally, we call SetWindowsHookEx and either wait for the event that we want or create our own using something like BroadcastSystemMessage. Once that event happens, Windows will load the DLL into the processes address space where it will be executed.


The following was adapted from code found here. First we load the DLL into the executable using LoadLibrary method. With GetProcAddress we get the address of the inject method from the DLL. Finally we set up a global hook (the parameter 0 will hook every thread in the current desktop) and wait for the program to be hooked.


Look at that! There is the message box running from the process we selected. Using Process Explorer we can see that the DLL is loaded into both Notepad++ and into the injector exe, which makes sense since the exe originally loads the DLL.


Download the Windows FS Injector tool for your workstation OS. The Injector tool, winfs-injector, is an executable binary that adds the Windows Server container base image into the product file. This step requires internet access and can take up to 20 minutes.


To deploy your TAS for VMs [Windows] app workloads to an isolation segment, select App Containers and follow the procedure in Assign a Tile to an Isolation Segment in Windows Diego Cells in Isolation Segments.


Like every patch maintenance, the lobby server will likely be taken offline as usual. Even assuming you get the patch downloaded and applied mid-maintenance, your authorization will almost assuredly be expired before things are back up.


So I have this DLL and this other thing which I think is refered to as a Injector / loader? It basically loads my DLL into the process of itself so it takes my DLL and loads it into the process of "Injector.exe"In the example down below it doesnt load it from resources but instead from the desktop, the same thing applies here.


There is a testdll.dll in the package folder of this project which will just open a new window from the process it was injected in which tells you when the dll is loaded and unloaded. There is also already a test js file in the test folder that you can run with npm test (be aware that for this to work notepad needs to be running and you are inside the package folder when executing npm test)


If your issue still persists, it is usually a firewall/antivirus blocking the download. Make sure the injector and the Rocket League installation folder called `rocketleague` are whitelisted in your antivirus. It could also be that a firewall on the router or elsewhere on the network is blocking the download. This is often the case on university networks and networks which are managed by other parties. For this, if possible, try tethering the download through another connection (if you can afford tethering 2.7mb, don't do this if you don't have any kind of data plan!). Another possible solution would be to use a VPN when updating. If none of these options are available to you, you need to manually install the updates every time Rocket League updates.
