rotection regulates and restricts operations, such as memory injection or memory dumping of protected processes, even from a process holding the SeDebugPrivilegeprivilege. Under the process protection model, only processes running with higher protection levels can perform operations on protected processes.

The _EPROCESSstructure, used by the Windows kernel to represent a process in kernel memory, includes a _PS_PROTECTIONfield defining the protection level of a process through its Type(_PS_PROTECTED_TYPE) and Signer(_PS_PROTECTED_SIGNER) attributes.

By writing in kernel memory, the EDRSandblast process is able to upgrade its own protection level to PsProtectedSignerWinTcb-Light. This level is sufficient to dump the LSASSprocess memory, since it "dominates" to PsProtectedSignerLsa-Light, the protection level of the LSASSprocess running with the RunAsPPLmechanism. EDRSandBlastimplements the self protection as follow:

* open a handle to the current process
* leak all system handles using NtQuerySystemInformationto find the opened handle on the current process, and the address of the current process' EPROCESSstructure in kernel memory.
* use the arbitrary read / write vulnerability of the Micro-Star MSI Afterburnerdriver to overwrite the _PS_PROTECTIONfield of the current process in kernel memory. The offsets of the _PS_PROTECTIONfield relative to the EPROCESSstructure (defined by the ntoskrnlversion in use) are hardcoded in the NtoskrnlOffsets.csvfile. Credential Guard bypassMicrosoft Credential Guardis a virtualization-based isolation technology, introduced in Microsoft's Windows 10 (Enterprise edition)which prevents direct access to the credentials stored in the LSASSprocess.

When Credentials Guardis activated, an LSAIso(LSA Isolated) process is created in Virtual Secure Mode, a feature that leverages the virtualization extensions of the CPU to provide added security of data in memory. Access to the LSAIsoprocess are restricted even for an access with the NT AUTHORITY\SYSTEMsecurity context. When processing a hash, the LSAprocess perform a RPCcall to the LSAIsoprocess, and waits for the LSAIsoresult to continue. Thus, the LSASSprocess won't contain any secrets and in place will store LSA Isolated Data.

As stated in original research conducted by N4kedTurtle: "Wdigest can be enabled on a system with Credential Guard by patching the values of g_fParameter_useLogonCredentialand g_IsCredGuardEnabledin memory". The activation of Wdigestwill result in cleartext credentials being stored in LSASSmemory for any new interactive logons (without requiring a reboot of the system). Refer to the original research blog post for more details on this technique. EDRSandBlastsimply make the original PoC a little more opsec friendly and provide support for a number of wdigest.dllversions (through hardcoded offsets for g_fParameter_useLogonCredentialand g_IsCredGuardEnabled). ntoskrnl and wdigest offsetsThe required ntoskrnl.exeand wdigest.dlloffsets (mentioned above) are extracted using r2pipe, as implemented in the ExtractOffsets.pyPythonscript. In order to support more Windows versions, the ntoskrnl.exeand wdigest.dllreferenced by Winbindex can be automatically downloaded (and their offsets extracted). This allows to extract offsets from nearly all files that were ever publ[...]

Is an ethernet connection required for mitm attacks?

I tried sniffing traffic through wifi and mitm a few months ago but was never able to sniff anything beyond basic traffic. Is an ethernet connection required for getting http requests and the like?

Similar style to the wifi pinaple

Hello all, do any of you guys know any of or software perhaps that can be used as an os for an rpi4 to mimic the feel of a wifi pineapple? Id love to have a os on my rpi that is basically a wifi pineapple so that i could just simply turn on my rasberry pi and access it through another web interface on a different device. Maybe you guys know like a software for kali that does this job well (ideally with a GUI/Web interface for conveniece). Basically anything that is like the wifi pinaple. Thanks in advancefor any suggestions.

Changing Account Info Illegal?

So to make a VERY LONG story short I was given the password to an account that manages internet service that is not my own, think the portal for paying your bill, etc. Well this particular internet service provider allowed you to manage your router in this portal, so I paused a devices WiFi, changed all the login, and contact info, and then logged out. Next day the owner of the account notices WiFi isn't working on a device so they call the ISP, they tell them how all the information was changed etc.

Is what I did technically illegal if I was GIVEN the password to this account a while back and I didn't use any exploits or hacks to gain access or change the info? Just the GUI of the website really lol.

Thank you in advance.

Canary Tokens

Hey I recently created a custom version of the canary tokens from canarytokens.org which is using the flask restful api library.

I know about 'request.environ' to get the basic data from a users request including IP etc., but is anyone aware of how to implement other calls to get more specific data from users requests?

The tool will be free when complete and I'll follow up with the link to deployed site where you can register and create your own tracking tokens (for educational purposes.....)
