In this machine, I used nmap, Evil-WinRm, Psexec, John, smbmap, enum4linux, crackmapexec, lookupsid.py and procdump.exe
First of all I ran a quick nmap scan for top ports
Following this I did some quick SMB checkings using smbmap and emum4linux
I could not authenicate I will need to try and enumerate for usernames so I decided to visit the open http port
I had a quick look through dev tools and found nothing interesting, there is login as a guest button though:
Upon looking in we find a username we can save for later as well as a cisco router configuration file:
Looking through the config we can indenify some hases for poetinal credintals:

There is one type 5 hash and two types 7
We can crack the type 5 hash with John
online decrypt
After decrypting I tested the password + users with crackmapexec
with my new SMB credintals time to try smbmap again:
I then ran the command again with -R to list all files
As IPC is used for interprocess communication we can connect with rpcclient
To save time I will use lookupsid.py by impacket
With the newly obtained users i ran crackmap again:
Connect with evilwin-rm
get user flag:
Privilege escalation:
typing PS i saw multiple instances of firefox running:
As I know firefox stores data in AppData I went to investigate
Identify which process:
More system usage more likely to be active browser
Getting firefox dump:
Downloading firefox dump:
downloading was taking too long decided to use findstr
looking through the output:
use psexec to test creds:
