# TryHackMe-THROWBACK-CORP-ADT01 (10.200.34.243)

We found credentials for `DaviesJ` but we won't be able to login we need to run autoroute on CORP-DC01
|

# TryHackMe-THROWBACK-CORP-01(10.200.34.118)
|
||||||
|
|
||||||
|
We can login with MercerH's credentials as this domain is trusted by THROWBACK.LOCAL but in order to do we need to run `autoroute` on DC because we cannot reach CORP domain through PROD
|
||||||
|
|
||||||
|
<img src="https://imgur.com/AJ34khU.png"/>
|
||||||
|
|
||||||
|
Here I downloaded meterpreter backdoor
|
||||||
|
|
||||||
|
<img src="https://imgur.com/WLCmUCo.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/B4mKgOR.png"/>
|
||||||
|
|
||||||
|
Now we have to remove route from previous sessions which in my case is `6` so I will use autoroute and `SET CMD delelte, SET SESSION 6` and then run it. After that I will `SET CMD autoadd , SET SESSION 7` and run the module

Seeing the commit history of the file `db_connect.php` we can find credentials

# TryHackMe-THROWBACK-DC01(10.200.34.117)
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
I used SSH to log on the domain controller
|
||||||
|
|
||||||
|
<img src="https://imgur.com/eEnWAsQ.png"/>
|
||||||
|
|
||||||
|
We can see that we are a normal domain user on this machine so we need to escalate our privileges and the only way to enumerate AD is to use bloodhound so by using the same loot we got from WS-01 we are going to utilize it
|
||||||
|
|
||||||
|
Using the query `Find Principals with DCSync Rights`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/Q2RPxq3.png"/>
|
||||||
|
|
||||||
|
Going into to the documents of jeffersd we find a notice
|
||||||
|
|
||||||
|
<img src="https://imgur.com/LYbWm2r.png"/>
|
||||||
|
|
||||||
|
Here there's a backup account password and we already found that `backup` has DCsync rights
|
||||||
|
|
||||||
|
```
|
||||||
|
DCSync is a late-stage kill chain attack that allows an attacker to simulate the behavior of Domain Controller(DC) in order to retrieve password data via domain replication
|
||||||
|
```
|
||||||
|
|
||||||
|
By running secretsdump.py we dumped hashes from NTDS.dit
|
||||||
|
|
||||||
|
<img src="https://imgur.com/sbSK2qG.png"/>
|
||||||
|
|
||||||
|
Now we have a bunch of user hashes but the problem how we can we know which user to target as we need to escalate our privileges so running a command `net localgroup` to see available groups on AD
|
||||||
|
|
||||||
|
<img src="https://imgur.com/EUBLwuO.png"/>
|
||||||
|
|
||||||
|
We can see there's a group `Administrators`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/G7NbGYD.png"/>
|
||||||
|
|
||||||
|
So we need to crack `MercerH` 's hash
|
||||||
|
|
||||||
|
<img src="https://imgur.com/LKSymjy.png"/>
|
||||||
|
|
||||||
|
To crack the hash we will be using a rules in `hashcat`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/dtuvAZL.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/XN9fu0a.png"/>
|
||||||
|
|
||||||
|
Simply ssh with the current logged in user
|
||||||
|
|
||||||
|
`ssh MercerH@localhost`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/ykyHgFH.png"/>
|
||||||
|
|
||||||
|
And you can see we are now a privleged user
|
||||||
|
|
||||||
|
|
||||||
|
```
|
||||||
|
THROWBACK.local\MercerH:pikapikachu7
|
||||||
|
JeffersD:Throwback2020
|
||||||
|
```
|
||||||
|
|
||||||
|
Going back to bloodhound we can see that THROWBACK.LOCAL domain is trusted by CORPORATE.LOCAL
|
||||||
|

### PORT 80 (HTTP)
|
||||||
|
|
||||||
|
<img src="https://imgur.com/gno4rk7.png"/>
|
||||||
|
|
||||||
|
We can see that there is a login page to pfsense control panel. I decided to try default credentials
|
||||||
|
|
||||||
|
<img src="https://imgur.com/YxPN6ai.png"/>
|
||||||
|
|
||||||
|
These credentials logged us in
|
||||||
|
|
||||||
|
<img src="https://imgur.com/9WiYRiq.png"/>
|
||||||
|
|
||||||
|
When logged in we can see `Diagnostics` tab and we see menu `Command Prompt`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/sO9kOgD.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/Ps3XdNV.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/ECdK1pb.png"/>
|
||||||
|
|
||||||
|
We can see that commands will be executed as `root`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/EpGlSAk.png"/>
|
||||||
|
|
||||||
|
Also php commands can be executed. I uploaded a `phpbash` which is like a backdoor having a full interactivev shell
|
||||||
|
|
||||||
|
`https://github.com/Arrexel/phpbash`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/ge8QtTL.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/wAdk1mU.png"/>
|
||||||
|
|
||||||
|
We can get the root flag in `/root/root.txt`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/ZB6J78n.png"/>
|
||||||
|
|
||||||
|
We can find logs for in `/usr/local/www`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/T65SEK1.png"/>
|
||||||
|
|
||||||
|
And we can get this this username and hash
|
||||||
|
|
||||||
|
`HumphreyW:1c13639dba96c7b53d26f7d00956a364`
|
||||||
|
|
||||||
|
I search for the log flag by running recusrive find command in `/var/log`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/aLfc5dk.png"/>
|
||||||
|
|
||||||
|
|
||||||
|
Now the hash that we got for the user `HumphreyW` we need to crack it but we need to know what type of hash it is so I went to `Name That Hash`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/HHCPKGI.png"/>
|
||||||
|
|
||||||
|
It gave me a bunch of hash type for it so I checked for MD5 and MD4 that was a negative
|
||||||
|
|
||||||
|
I started `hashcat` for NTLM (1000)
|
||||||
|
|
||||||
|
<img src="https://imgur.com/vecXikO.png"/>
|
||||||
|
|
||||||
|
And it was cracked
|
||||||

We can login with the guest credentials which are
|
||||||
|
|
||||||
|
`tbhguest:WelcomeTBH1!`
|
||||||
|
|

<img src="https://imgur.com/LOmrerX.png"/>

We can get our first flag form the inbox

Going to `Addresses` tab we can see a list of usernames and emails

We have the usernames but don't have the passwords but it was told that some accounts might use weak credentials so I crafted some passwords

### PORT 80 (HTTP)
|
||||||
|
|
||||||
|
<img src="https://imgur.com/JBjLauV.png"/>
|
||||||
|
|
||||||
|
Since this host has AD running so we can run a tool called `responder` to start an attack called LLMNR/NBT-NS poisoning
|
||||||
|
|
||||||
|
<img src="https://imgur.com/OpMmDhq.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/kweooie.png"/>
|
||||||
|
|
||||||
|
I ran this tool for 2 days and it didn't gave me the hash , there was a problem in Throwbacks network so I had to continue looking up the writeups
|
||||||
|
|
||||||
|
### Remmina
|
||||||
|
|
||||||
|
Since this windows machine has port 3389 open which is for `Remote Desktop Protocol` we can login with PetersJ's passoword which is `Throwback317`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/KeBEkmk.png"/>
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
### Installing Starkiller
|
||||||
|
|
||||||
|
Starkiller is C2 (Command and Control) frontend interface for "Empire" used for post exploitation without interfereing with the actual machine it self. It is used for enumeration and for identifiying privilege escalation vectors so for that we need to have `starkiller` and `empire`
|
||||||
|
|
||||||
|
|
||||||
|
<img src="https://imgur.com/22d5PmO.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/RJoPGls.png"/>
|
||||||
|
|
||||||
|
Now we have to `chmod +x starkiller-1.3.2.AppImage` and `./starkiller-1.3.2.AppImage --no-sandbox`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/iBx880x.png"/>
|
||||||
|
|
||||||
|
We will be presented with a login prompt
|
||||||
|
|
||||||
|
<img src="https://imgur.com/b6nbxVz.png"/>
|
||||||
|
|
||||||
|
### Installing Empire
|
||||||
|
|
||||||
|
Empire is great tool similar to meatsploit for post exploitation and information gathering used on windows machines
|
||||||
|
|
||||||
|
Run `git clone https://github.com/BC-SECURITY/Empire.git`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/AeIlyAT.png"/>
|
||||||
|
|
||||||
|
Run `install.sh`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/S5YIcIj.png"/>
|
||||||
|
|
||||||
|
This installation would take a long time. So going back to starkiller we log in with the credentials `empireadmin:passowrd123` and we need to make this application listen on defualt port which is `1337` leet but in order login we want empire to be running
|
||||||
|
|
||||||
|
<img src="https://imgur.com/yQgRlJ8.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/LH0xXgZ.png"/>
|
||||||
|
|
||||||
|
So our installation for empire is complete but still we need to install some dependencies
|
||||||
|
|
||||||
|
`pip3 install poetry` and `poetry install` then `poetry run python empire`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/T0CKmLl.png"/>
|
||||||
|
|
||||||
|
One last thing to do `pip3 install click` and when you run `powershell-empire`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/oI7bFsl.png"/>
|
||||||
|
|
||||||
|
And it works but we need to use it with `--rest`,so
|
||||||
|
|
||||||
|
<img src="https://imgur.com/uznPAGc.png"/>
|
||||||
|
|
||||||
|
By using this option it will use the default ports and will allow us to use frontend which starkiller
|
||||||
|
|
||||||
|
<img src="https://imgur.com/jSKqMUA.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/s08duZJ.png"/>
|
||||||
|
|
||||||
|
On logging in with the default credentials above
|
||||||
|
|
||||||
|
<img src="https://imgur.com/XcK3Ffr.png"/>
|
||||||
|
|
||||||
|
Now we are going to create our listener
|
||||||
|
|
||||||
|
<img src="https://imgur.com/C9c6HbQ.png"/>
|
||||||
|
|
||||||
|
We have our listener created
|
||||||
|
|
||||||
|
<img src="https://imgur.com/nLlDDRu.png"/>
|
||||||
|
|
||||||
|
Now we need to create our stager which is the payload we are going to transfer on the target machine
|
||||||
|
|
||||||
|
<img src="https://imgur.com/jQ2n0qf.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/CWUgbh5.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/SbqbSpy.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/dpeTD8a.png"/>
|
||||||
|
|
||||||
|
Click on the download or save icon to save the payload somewhere on your local machine and then start a python3 http server to host it in order to download it from the target machine
|
||||||
|
|
||||||
|
<img src="https://imgur.com/Ydsqj2a.png"/>
|
||||||
|
|
||||||
|
The web server is running
|
||||||
|
|
||||||
|
<img src="https://imgur.com/kQToAFI.png"/>
|
||||||
|
|
||||||
|
We have that on the target machine all we need to do is launch the payload
|
||||||
|
|
||||||
|
On launching we will see some information regarding the target machine in the `agents` section
|
||||||
|
|
||||||
|
<img src="https://imgur.com/4XJE4QP.png"/>
|
||||||
|
|
||||||
|
We can see that starkiller is acting like C2 server which sends commands on the target machine and we can see the output over the GUI
|
||||||
|
|
||||||
|
<img src="https://imgur.com/i0l8yno.png"/>
|
||||||
|
|
||||||
|
Run `seatbelt` module
|
||||||
|
|
||||||
|
<img src="https://imgur.com/QBkCLbY.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/jDwhgPE.png"/>
|
||||||
|
|
||||||
|
This module did enumeration for us a found a user with a saved credential
|
||||||
|
|
||||||
|
<img src="https://imgur.com/7xIrk2n.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/L9ln4k5.png"/>
|
||||||
|
|
||||||
|
Now we have logged in as `admin-petersj` in order to dig deep we have to run mimikatz but for that we need to create another listener and stager in order to run c2 commands as elevated user
|
||||||
|
|
||||||
|
<img src="https://imgur.com/bLpUqC1.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/zA88wGT.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/cng57Ba.png"/>
|
||||||
|
|
||||||
|
On running this payload again
|
||||||
|
|
||||||
|
<img src="https://imgur.com/xvHivNX.png"/>
|
||||||
|
|
||||||
|
Now we need to run `mimikatz` module through our C2
|
||||||
|
|
||||||
|
<img src="https://imgur.com/lr1IlWS.png"/>
|
||||||
|
|
||||||
|
Running `privilege::debug` will give us a status `OK` means we can escalate our privileges to NT-AUTHORITY
|
||||||
|
|
||||||
|
<img src="https://imgur.com/QCrgIh9.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/YyeUrWC.png"/>
|
||||||
|
|
||||||
|
We ran the command and notice if scroll down a little be we can see the password hashes of the users
|
||||||
|
|
||||||
|
<img src="https://imgur.com/KN0s9k0.png"/>
|
||||||
|
|
||||||
|
There's a feature in Starkiller which can save all the credentials or hashes found in a neat way
|
||||||
|
|
||||||
|
<img src="https://imgur.com/HLRA0Gq.png"/>
|
||||||
|
|
||||||
|
Now we have the credentials but don't know on which host these credentials are valid so we are going to something called` Pass The Hash` a realy attack for that we need to run `proxychains` or `autoroute` for that we need to have meterepreter session
|
||||||
|
|
||||||
|
<img src="https://imgur.com/s3zJGOS.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/ZhlxTI1.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/qnU0AuG.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/gta3t5x.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/2ZpOIBh.png"/>
|
||||||
|
|
||||||
|
Install `Crackmapexec`
|
||||||
|
|
||||||
|
https://github.com/byt3bl33d3r/CrackMapExec/wiki/Installation#binaries
|
||||||
|
|
||||||
|
<img src="https://imgur.com/NWSK4mb.png"/>
|
||||||
|
|
||||||
|
We can see that we can ping the ohter machines as well so the task says that the hash from task 10 will work which was from `HumprehyW` 's hash and the other from the list of credentials we dumped using mimikatz
|
||||||
|
|

Now we need to run this tool `LeetLinked`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/mAolcZu.png"/>
|
||||||
|
|
||||||
|
This returned as a list of emails
|
||||||
|
|
||||||
|
<img src="https://imgur.com/0nO4zCc.png"/>
|
||||||
|
|
||||||
|
But we need to convert the format which found from a note in dosierk's documents. So we will be using `namely` to generate emails in a proper format using names we found from `leetlinked`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/pQdjR2d.png"/>
|
||||||
|
|

|
<img src="https://imgur.com/juRsXJg.png"/>
|

Now this in HRE format but there are other formats as well
|

|
||||||
|
|
||||||
|
<img src="https://imgur.com/xUI3yGl.png"/>
|
||||||
|
|
||||||
|
In this I generated a list of potential emails now only thing left for us to do is to visit `breachgtfo.local` and check for breached emails
|
||||||
|
|
||||||
|
<img src="https://imgur.com/xQzcFI9.png"/>
|
||||||
|
|
||||||
|
We can use `wfuzz` to check for response length
|
||||||
|
|
||||||
|
<img src="https://imgur.com/X7hwkzj.png"/>
|
||||||
|
|
||||||
|
We get the same amount of Characters so we can hide `4950` and see if there are characters with a length other than that
|
||||||
|
|
||||||
|
<img src="https://imgur.com/gGyaXgq.png"/>
|
||||||
|
|
||||||

And we have found a request with different characters

Upload that document
|
||||||
|
|
||||||
|
<img src="https://imgur.com/wMsI47W.png"/>
|
||||||
|
|
||||||
|
You will get a shell

|
By typing `sysinfo`
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
We can see that we are on a 64 bit windows architecture but on 32 bit merterpreter session so we need to migrate to a 64 bit process. Running command `ps` to check currently running processes
|
||||||
|
|
||||||
|
<img src="https://imgur.com/bdOCw2v.png"/>
|
||||||
|
|
||||||
|
Here we need to identify the process which is running as `NT AUTHORITY\SYSTEM` also running as a 64 bit
|
||||||
|
|
||||||
|
<img src="https://imgur.com/463bpoZ.png"/>
|
||||||
|
|
||||||
|
So we see this statisfying our requirements
|
||||||
|
|
||||||
|
<img src="https://imgur.com/4hK07Bz.png"/>
|
||||||
|
|
||||||
|
And now we are the highest privileged user also now our meterpeter session is on 64 bit architecture
|
||||||
|
|
||||||
|
<img src="https://imgur.com/E32Xkih.png"/>
|
||||||
|
|
||||||
|
We can now run commands like mimikatz , hashdump
|
||||||
|
|
||||||
|
<img src="https://imgur.com/QbbtiWT.png"/>
|
||||||
|
|
||||||

We have successfully dumped the hashes of the accounts on this machine
|
||||||
|

|
|

|
Using proxychains we ssh with `Timekeeper's` credentials
|
||||||
|
|
||||||

Save the list of usernames you found from `domain_users` database
|
||||||
|
|
||||||
|
<img src="https://imgur.com/h5Eomzj.png"/>
|
||||||
|
|
||||||
|
We can utilize the same list of passwords we used to get access to Throwbacks mail
|

## NMAP
|
||||||
|
|
||||||
|
```
|
||||||
|
No ports open on this machine
|
||||||
|
```
|
||||||
|
|
||||||
|
We can get `user.txt` flag from here
|
||||||
|
|
||||||
|
<img src="https://imgur.com/xsRg9Ay.png"/>
|
||||||
|
|
||||||
|
And for `root.txt`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/cUSPJ4C.png"/>
|
||||||
|
|
||||||
|
Since we have ran `autoroute` on `THROWBACK-WS01` we can access machines on the network as we were not able to run nmap scan on this machine
|
||||||
|
|
||||||
|
<img src="https://imgur.com/OGgwf4O.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/yFaKuRh.png"/>
|
||||||
|
|
||||||
|
We can ssh into the machine with BlaireJ's plain text password
|
||||||
|
|
||||||
|
<img src="https://imgur.com/PJ4HyKK.png"/>
|
||||||
|
|
||||||
|
Now that we have gained inital foothold on WS-01 again we need to do some enumeration with `Bloodhound`.
|
||||||
|
|
||||||
|
After installing it on kali machine we can the GUI interface on browser
|
||||||
|
|
||||||
|
<img src="https://imgur.com/Ybb3IsB.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/RgkCUOG.png"/>
|
||||||
|
|
||||||
|
Now we need to download a file called `Sharphound.ps1` a powershell script to be transfered on WS-01 machine
|
||||||
|
|
||||||
|
https://github.com/BloodHoundAD/BloodHound/blob/master/Collectors/SharpHound.ps1
|
||||||
|
|
||||||
|
To run the script we need to disable antivirus or windows defender on the target machine
|
||||||
|
|
||||||
|
https://www.itechtics.com/enable-disable-windows-defender/
|
||||||
|
|
||||||
|
`Set-MpPreference -DisableRealtimeMonitoring $true`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/AlJDpuw.png"/>
|
||||||
|
|
||||||
|
Then run this command to get a map of the AD environment
|
||||||
|
|
||||||
|
`Invoke-Bloodhound -CollectionMethod All -Domain THROWBACK.local -ZipFileName loot.zip`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/NfjVTcj.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/cGKVQsb.png"/>
|
||||||
|
|
||||||
|
Now we need to get this `20210227114234_loot.zip` on our machine
|
||||||
|
|
||||||
|
I messed up with the credentials and didn't found a way to reset so I disabled the authentication
|
||||||
|
|
||||||
|
`subl /etc/neo4j/neo4j.conf`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/PuD7Ala.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/35t7laC.png"/>
|
||||||
|
|
||||||
|
Copy that zip file from the target to our local machine
|
||||||
|
|
||||||
|
<img src="https://imgur.com/HZvlGCp.png"/>
|
||||||
|
|
||||||
|
Simply drag and drop to bloodhound GUI and run quries example get all admins
|
||||||
|
|
||||||
|
<img src="https://imgur.com/C9Sr8Mc.png"/>
|
||||||
|
|
||||||
|
Run the query `Map Domain Trusts`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/aHAiDSP.png"/>
|
||||||
|
|
||||||
|
|
||||||
|
Run the query `List all Kerberoastable Accounts`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/awmL00s.png"/>
|
||||||
|
|
||||||
|
|
||||||
|
Run the query `Find Shortest Paths to Domain Admins`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/Y5sHUPg.png"/>
|
||||||
|
|
||||||
|
Now in order to get kerbroast ticket we need the impacket version 0.9.19
|
||||||
|
|
||||||
|
https://github.com/SecureAuthCorp/impacket/releases/tag/impacket_0_9_19
|
||||||
|
|
||||||
|
Reason is if we run with latest version
|
||||||
|
|
||||||
|
<img src="https://imgur.com/RCdKOTU.png"/>
|
||||||
|
|
||||||
|
We won't get the kerbroast ticket of SQLSERVICE account so on running with older version
|
||||||
|
|
||||||
|
<img src="https://imgur.com/gJvzinj.png"/>
|
||||||
|
|
||||||
|
On getting that kerbroast hash we need to crack it using `hashcat`
|
||||||
|
|
||||||
