one thing that i appreciate about your videos is that you zoom the screen big enough to make it easier to read and watch. and i think people don't point that out enough. thanks.

You can zoom any video on phone and laptop/desktop. Either pause it or not : On phone use 2 fingers on the screen and move then the opposite direction. On laptop/desktop, use the magnifier. (Windows key+CTRL+M) Google it, there is other ways too.

i find it odd that microsoft keeps opting to HIDE extension names by default even going as far as force-hiding it even if you set it to always show, like in this case of SCF files. it's like microsoft is allowing threat actors in making windows vulnerable. it's their MacOS/Linux obsession that's influenced this compromised design decision

The point is clear - you have just to make somehow a request from victim PC via SMB, fool it that you're going to authenticate it and it gives you it's NTLM hash. But, I couldn't replicate this attack (at least this way). I've done exactly how did you in video and simply nothing happened. Responder was listening correctly and all VMs were in the same network. Windows 10 nor Windows 7 responds to this. Guest OS: Windows 10, Kali Hypervisor: Virtualbox Networking: Bridged (both of them)

Thanks for sharing! Good to see this is possible, something to be alert for. When I think of protection, blocking SCF files in Ivanti Workspace for example, could prevent this. As for monitoring, detection and response I'm thinking anti virus and SIEM tooling and a SOC to respond to alerts. This covers anti malware and monitoring and logging in ISO27001.

@SzaboB33 8 ай бұрын

A small correction: You meant "relay" the hash not "pass" because pass the hash attacks are different than NTLM relay attacks. It's quite confusing because of the misused terminology (I did it in the previous sentence as well for traditional reasons :D). But the pass-the-hash attack uses the password hash stored on the machine to generate NetNTLMv2 hashes that will be sent through the network. Relay attacks catch a NetNTLMv2 hash (just like responder does) and sends it through to another service that accepts NTLM authentication. Key differences: NetNTLMv2 hashes cannot be used for long, they expire. SMB signing (in case of SMB servers) can defend against relay attacks (but it will have like a 30% performance cut) while pass-the-hash attacks will work even if it's enabled.

@craigblackie2034 8 ай бұрын

You wouldn't be able to "pass the hash" this isn't ntlm, this is a different format known as net-NTLM, you can relay this though, so long as there is no signing in place.

@craigblackie2034 8 ай бұрын

And yes, you can get ntlm from net-ntlmv1, but that involves a cracking process still.

Alright, so you can set a custom icon for a richtext file or word document... 🤷‍♂ Seems cool, but noone really uses it afaik. But then allowing a network location for an icon, on a local document file is really odd🤦‍♂, I don't think anyone asked for that feature whatsoever.

I just did something like this not that long ago and pwnd the SOC for the folks that I was working for. I downloaded an SCF to my computer which pointed to my host on the Internet, well the SOC saw the file saved it their desktop and all of the sudden I had a connection to my host from one of the SOC users (which BTW had admin rights on an S* load of systems) after that I used his credentials, with pass the hash, to own the place.

I've gotten this to work on Windows 11. How are you setting the icon path? I have had the most success when I wrap it in double quotes and use forward-slashes rather than backlashes, i.e. "//10.0.0.155/share/fake.ico"
