Hello there. I hope I am not intruding on your busy schedule. I was just wondering if you knew whether someone found a fix to this that doesn't involve the removal of the new text file option?

[@twcziggybomz187]

Hey Chuck , ive actually come across the exact same thing yesterday except it wasnt a word document. It was a whole installation ISO of Windows 11 Pro , which my brother downloaded from the Pirate Bay. it triggered instantly once the installation was completed , and had some more effects to it whereby it damaged hardware so bad that the bios was messed up as well.

[@AnotherSkyTV]

You mean it ran this diagnostic tool window once installation was finished?

[@twcziggybomz187]

@@AnotherSkyTV yes once instalation was finished , pc rebooted , once signed in diagostic popped up

[@moth5799]

An ISO that you use at boot has basically full access to your system, not a good idea to download that from a pirate site without checking it in a VM first at least, msdt is the least of your issues when it comes to that lmao

[@steps0x029a]

Windows Defender seems to have caught up with Follina. Word still reaches out to the server, but that's it. You get a warning and nothing else is happening - at least with my setup, don't feel too safe. I really like the idea of Chuck and John making content as a team, by the way!

[@MrSpyLiam]

It depends on what you do with Folina. Hackers are experts in remaining undetected. What Chuck shows you is a very basic attack, but in real life instances victims wouldn't know that anything has been done, other than that they open a Microsoft product and the troubleshooting window runs.

[@steps0x029a]

@@MrSpyLiamof course. But as Defender seems to actually prevent the execution, it shouldn't really matter what payload is used. I might be wrong, though 🤷🏻‍♂️

Thanks for you work I love it. Tested it out and got it working. I wonder if the company I work for would have to worry about this. Sure they have it blocked already but you never know. Company is world wide

[@theaifam5]

34 is not a “weird obfuscation” but just “ required so the Base64 receives payload string and decodes it and executes it, like a normal function call where the argument is a string, in this case, a base64 encoded payload

its really awesome that this video references what you learn in the Hack the box course.

[@djscuffedjays5155]

[@ChristianPixtun]

You should really do a playlist explaining these vulnerabilities. Yes, there are channels explaining this stuff, but with you and your way of teaching things, explaining a CVE and how it works is a must for security professionals, especially if they want to be blue or red team pros, or even us, who are just passionate of these things. Do a playlist!!!!!!

Also interesting stuff besides follina: python web server and adding a NAT network in VirtualBox on-the-fly. Got it running. Thx a lot!

[@StephenCurry-nm7io]

In essence, exploits of Follina involve a Word document containing a web link to an attacker-controlled web resource. Since Word automatically fetches such embedded links, the attacker may specially crafting their content such that it invokes a MSDT instance which may be used to force the execution of attacker-supplied Powershell commands. However, you failed to mention that Follina may be exploited in a zero-click fashion using a file in an .rtf format which runs the code via the Preview Tab in Explorer.

[@WJPearce_]

In well preped .rtf you don't even need user interaction. The preview of .rtf in windows explorer is enough. Maybe event outlook preview of .rtf file attachment - not sure rn.

[@devinbrasher6752]

You can find it by reverse engineering msdtc.exe with Ghidra. There's a void function (doesn't accept arguments) that assigns GetCommandLineW() to its initial variable, and then calls another function that invokes StringCchCopyA() to pass the payload into the return value for GetCommandLineW(), which is a pointer to the command-line string for the current process.

[@brandonbaldwin3095]

Fix: Admin command prompt type: “reg export HKEY_CLASSES_ROOT\ms-msdt msdt_bkup” “reg delete HKEY_CLASSES_ROOT\ms-msdt” Prevents the back door of msdt from being exploited. The back door is via the online template connection word uses which is tunneled through msdt. The attacker exploits the connection redirecting to payload. If you already been a victim this will not help you, you’re already pwned.

You can actually get around it by adding specific keys to the registry of systems. Not a microsoft fix but it will protect you.

By deleting the ms-msdt key, not by adding. Remove-Item REGISTRY::HKEY_CLASSES_ROOT\ms-msdt -Recurse -Force OR reg delete HKEY_CLASSES_ROOT\ms-msdt /f Make sure to backup first (reg export HKEY_CLASSES_ROOT\ms-msdt $env:USERPROFILE\Undo_FollinaFix_MS-MSDT.reg)
