anyone used ys******l on kali, if you managed a way to do that on kali please PM me

Same here! I am looking for a way to construct the payload without resorting to setting up a Windows VM (is compilation required too?). Please PM if anyone knows how to do it in kali.

Hello,

Yes , it’s possible using wine and installing mono in wine as described below:

You must do the installation on GUI , so don’t try it in console :slight_smile:

Read carefully , you don’t need to install mono using apt install

HTH

Hello im have problem with get shell, server get from my server files and in next step i can’t run it on the server. Anyone has any tips to get shell? Im talking about user part.

Hi, just like to get some help with initial payload for JSON, i am able to ping back, so I know that works, however not able to execute other commands which I can do locally. PM please

Able to use ys*******.n** to get ping to work but not getting any joy from next efforts to move a useful file over and execute for a shell. Have tracked with tcpd*** but not seeing anything to help me. Would appreciate a nudge if anyone is willing to offer one.

Edit: Finally got user. I needed a nudge on syntax with ys*******.n** and got it sorted. Onto some digging into the server now that I have a shell.

Would anyone be available to assist me
Using the potatoes, I was able to grant myself group memberships but I am unable to get a reverse shell.
I’ve validated with a few folks and what I am doing should work… I’m baffled

When you create payload you must pay attention to quotation marks and escaping it. Im have some problem and resolve it by escaping.

i use ys*********.jar… pls mesage for help.

You must use ys*******.**t. This one is correct for the technology of this application.

Wow very interesting machine. Really want to learn why the whole foothold works, I understand it vaguely but really don’t get why it works. Great system to practice for my AWAE test coming up! Privesc was great too!

meterpreter > getuid
Server username: NT AUTHORITY\SYSTEM
meterpreter > sysinfo

I get it too. I wonder if it’s not the fault “OS Version: 6.3.9600 N/A Build 9600”

You must get good CLSID to use juice

Send me a PM with which bit exactly you didn’t understand and I’ll try explain

EDIT: Ended up writing a pretty comprehensive explanation of exactly how the y******.**t part of this box works to send to @m4ng0n3l and had to put it on dropbox because HTB banned me for 15 mins when I tried to send it to him directly for some reason lol so if anyone else wants a copy of that (only AFTER you’ve got the user flag and just want to understand how/why it worked) then drop me a PM and I’ll send it over.

could I use a nudge on initial foothold. managed to get ping back to my machine but no other payload i tried works

Got this one, after spending a day to set up the Visual Studio on a windows VM. Pure guess work that the B… header would de… Getting root was relatively easy with a spud.

Do you escape characters in payload ?

It is easy if u know the methods , but hard for me cuz i am noob

Forums nudges are more than enough to own the box, have fun !

special thanks to @Schecken @icoNic @VsamlAmV for explanations
