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.

SMB seems like it's primarily a vulnerability generating protocol that just happens to also let you share files

really seems like Microsoft should implement some security measures for these scf files

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)

Yooo, I swear you always have the most absurd things in windows to perform malicious actions with, absolutely love it!

I'm too dumb to understand everything You present, but how I have been told "I love when You speak technical to me"

Running and gunnin! Hotel YT production. Good to see you John! Great video

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.

Thank you for the awesome content, Scary that this works on network file shares and USB drives.

Love, John Hammond. :)

It's really cool to get this working :P Love your content!

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.

Thanks John, you the boss!

ok that is really cool. Thank you for doing these types of videos.

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.

Hi John, Thank you for all the information you share with all of us! I need some help some Russians hacked my email account so I have changed all passwords as required. I have the ip address it was accessed from. How can I revert their action towards them back?

Wonder if all these vulnerabilities are recognized by Huntress?

So powerfull! If a read teamer put this file in a smb share for example, whould the .ico be fetched by any viewers of the share? Or the ico will be cached by the DC?

yow John, unrelated topic here, just want to ask if you know how to install linux mint or ubuntu dual boot with windows 10 if i don't have flash drive and dvd to create bootable installer. thanks

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.

Hey John big fan here, one thing though I noticed that this only works on windows 10 and does not give me the hash when I tried it on windows 11 is there any reason for that?

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"

thats mad, and i alrway riht click recycle bin to empty it i never open it luckily but i see the point any icon can be used lol

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.

"I'm trying to drag this file to the bin but it just WILL NOT GO IN THERE" 😅🤣 Another fun option would be to change the right-click context options for this file to look like it is a recycle bin - the context menus for the bin vs. files look pretty different and someone who is apprehensive might be able to figure out something is up just by right clicking the file and seeing no recycle-related-options. But maybe not if it looks exactly like the bin menus. OR ... could you somehow link the trap file to the REAL recycle bin, and simply pass the user in a way that looks normal? (IE: logs info, then just opens the real recycling bin so fast the user would never notice)
