Hello everyone , in this post I will be sharing my write up for the retired HTB Heist machine , which is rated as easy windows machine but there were a lot steps involved getting administrator on this box and the process was really time consuming .


PORT      STATE SERVICE       REASON          VERSION

PORT 445 (SMB)

Since smb service is running we can see if anonymous login is enabled on smb or not

Looks like it isn’t useful for so let’s move on to port 80


On the webserver we can see a login page

So let’s try the usual admin:admin

But this asks us to enter email address , there’s login as guest option available to us so let’s see what it does

In parallel I started running gobuster

It seems there’s nothing interesting that I found so on viewing the attachment Hazard sent

We can see a Cisco IOS MD5 hash and two ciso type 7 passwords use a very weak algorithm that can be easily reversed, so going to a online tool for decrypting the two passwords

Also we have 3 usernames rout3r , Hazard and admin and we got two decrypted passwords except for the hash, so let's try to brute force for that I'll make a wordlist for usernames and passwords ,for brute forcing I used crackmapexec against smb.

So it failed maybe we do need to crack that hash, so let’s fire up hashcat and crack that hash, we can see the hash format number from hashcat examples wiki page

Awesome we cracked the hash ,let’s add this to our passwords wordlist and see if this makes a difference

Nice ,we got the correct credentials let’s try to access smb and see how many shares are there

We can only access IPC share , I don't know if that would be much of a use for us, so now I was only left with running enum4linux-ng since we have the creds for smb we can run it now

Now we got bunch of usernames so we can try brute forcing on both smb and winrm protocol

It shows that status pwned so it means we can get a shell , we can use evil-winrm to login to target machine using the credentials

I first decided to look for running processes and found firefox to be running

So maybe firefox may have saved credentials so we need to go to the path where firefox files are stored under a user

Now we have to transfer these files on to our machine , luckily evil-winrm supports downloading files or folders just by specifying download and then the file/folder name

I searched for a tool that can recover or decrypt passwords from firefox files and I found a python script on github


But I ran into some errors

I then decided to follow this blog posts where it shows dumping creds using metasploit module


For that we need a meterpreter shell so let’s just generate a windows payload ,upload and execute it

profile doesn’t exist to there are no saved passwords on firefox browser so we can’t proceed further. Now nothing was coming into my mind except that firefox browser is currently running so I searched for dumping firefox process and this came up

So we can use procdump a sysinternal tool to dump firefox's process and run strings command on it to get the password maybe, I downloaded the tool from microsoft's site

Run ps on meterpreter to see the running processes and we can see the process ID of firefox

Now we need to run procdump to dump process of firefox and transfer it on our machine

But the dump’s size was 293 MB so I decided not to transfer it and instead use strings.exe which is another tool from sysinternal tools

But we don’t know what parameters we need to look for so I decided to intercept the web page with burpsite

But it wasn’t working on the target machine so I had to download it on my machine

We can now just run strings and grep for any of the parameters we saw earlier

Now we can just login as Administrator with the password through evil-winrm but I wanna dump all hashes so we can use impacket's seceretsdump.py do dump hashes from SAM Security Account Manager
