kandi X-RAY | ScareCrow Summary

ScareCrow is a Go library typically used in Security, Cybersecurity applications. ScareCrow has no bugs and it has medium support. However ScareCrow has 1 vulnerabilities. You can download it from GitHub.

ScareCrow is a payload creation framework for side loading (not injecting) into a legitimate Windows process (bypassing Application Whitelisting controls). Once the DLL loader is loaded into memory, it utilizes a technique to flush an EDR’s hook out of the system DLLs running in the process's memory. This works because we know the EDR’s hooks are placed when a process is spawned. ScareCrow can target these DLLs and manipulate them in memory by using the API function VirtualProtect, which changes a section of a process’ memory permissions to a different value, specifically from Execute–Read to Read-Write-Execute. When executed, ScareCrow will copy the bytes of the system DLLs stored on disk in C:\Windows\System32\. These DLLs are stored on disk “clean” of EDR hooks because they are used by the system to load an unaltered copy into a new process when it’s spawned. Since EDR’s only hook these processes in memory, they remain unaltered. ScareCrow does not copy the entire DLL file, instead only focuses on the .text section of the DLLs. This section of a DLL contains the executable assembly, and by doing this ScareCrow helps reduce the likelihood of detection as re-reading entire files can cause an EDR to detect that there is a modification to a system resource. The data is then copied into the right region of memory by using each function’s offset. Each function has an offset which denotes the exact number of bytes from the base address where they reside, providing the function’s location on the stack. To do this, ScareCrow changes the permissions of the .text region of memory using VirtualProtect. Even though this is a system DLL, since it has been loaded into our process (that we control), we can change the memory permissions without requiring elevated privileges. Once these the hooks are removed, ScareCrow then utilizes custom System Calls to load and run shellcode in memory. ScareCrow does this even after the EDR hooks are removed to help avoid detection by non-userland, hook-based telemetry gathering tools such as Event Tracing for Windows (ETW) or other event logging mechanisms. These custom system calls are also used to perform the VirtualProtect call to remove the hooks placed by EDRs, described above, to avoid detection by any EDR’s anti-tamper controls. This is done by calling a custom version of the VirtualProtect syscall, NtProtectVirtualMemory. ScareCrow utilizes Golang to generate these loaders and then assembly for these custom syscall functions.

            Json Serialization error expected start of the array "[" but had EOF instead
            Asked 2022-Mar-26 at 11:50

            I am currently learning Kotlin Multiplatform and i'm trying to serialize a Json using the ktor Framework. I receive the JSON from the following api: https://opentdb.com/api.php?amount=10 But i am getting this error: "error: Expected start of the array "\[" but had "EOF" instead. JSON input: .....answers":\["Patrick Swayze","John Cusack","Harrison Ford"\]}\]}" The JSON i receive looks something like this: { "response_code": 0, "results": [ { "category": "Entertainment: Film", "type": "multiple", "difficulty": "easy", "question": "What breed of dog was Marley in the film "Marley & Me" (2008)?", "correct_answer": "Labrador Retriever", "incorrect_answers": [ "Golden Retriever", "Dalmatian", "Shiba Inu" ] }, { "category": "Entertainment: Comics", "type": "multiple", "difficulty": "hard", "question": "In the Batman comics, by what other name is the villain Dr. Jonathan Crane known?", "correct_answer": "Scarecrow", "incorrect_answers": [ "Bane", "Calendar Man", "Clayface" ] }, { "category": "Entertainment: Film", "type": "boolean", "difficulty": "easy", "question": "Han Solo's co-pilot and best friend, "Chewbacca", is an Ewok.", "correct_answer": "False", "incorrect_answers": [ "True" ] } ] }

            In the insert expression, you are telling the XQuery engine to insert the node before //musica. However, is the root node of the document, so inserting a node before it would cause the XML file to be non-well-formed. I would expect the engine to throw an error.

            If your goal is to insert the element into the element, you would use the following expression:

            Maybe the issue is related to the "ASPNETCORE_ENVIRONMENT" variable setup. We have to provide this information in IIS.

            You can actually set it on the website in IIS.

            • Open the "Internet Information Services (IIS) Manager.

            • Go to the Website where you want to set the environment variable. Find the "Configuration Editor".

            • In the "Section" part of Configuration Editor, select system.webServer/aspNetCore in the left dropdown select ApplicationHost.config.

            • Click on environmentVariables then you will get the Current env variable. Add a new env variable.

            • name will be ASPNETCORE_ENVIRONMENT and value will be Development[staging/Prod].

            • Close the window and restart the website.

            Give a try with the above. Happy Coding!!

            You can use .reduce() with an object as an accumulator. For each key in the object, you can use a combination of the code and relationship. Then, for each object in your array, if you encounter a key in the accumulator object which matches the code+relationship of your current object you can add the name to value array held by the accumulator:
