HackTheBox: Legacy Windows XP SP3 SMB Walkthrough

-

The Hack Walkthroughs are back! The plan is to hack 40 boxes before I sign up for Offensive Security's PWK 60-day training. I need to prepare before I prepare. I need to train before I train! I read online people were regretful they started with PWK first. I paid for VIP on hackthebox.eu which was $10.

I'm taking a very long Udemy course and the guy gets into legacy HTB boxes. I'm going to hack them before he shows the answers. I appreciate he put them in order so I have a map on where to go next.

The first problem I encountered was switching my openvpn file once I paid for VPN. The answer was to reboot.

The first thing I do is nmap the host. I had to use -Pn because nmap thought the host was down. I also couldn't use -A -p- because it took forever. I relied on the top 1000 ports instead.

I mean, its an easy box so this is a good start. I tried to smbclient connect and it failed. I got into msfconsole and used the smb_version scanner to see what I was dealing with.

This result makes me happy. Windows XP sounds great to me. I then googled to see if an SMB exploit existed and got this:

Rapid7 shows up who make the tool metaspoit. It also shows the module path. I copied the module path. Now LHOST is automatically set up to my NAT IP address. This is wrong. I need to use the openvpn IP address I got from HTB. I changed it to 10.10.14.27 instead of my 192.168.154.153. Kali has multiple network adapters. Routing can't get to me on 192.x but it can on 10.x.

Psss: So glad my CCNA is helpful.

That's it. Once you set the LHOST and RHOST, hit run. The default payload worked for me. I'm glad it did, because there were 87 different payload options.

The commands "ls", "pwd", and "cat" worked. I'm going to assume the payload is translating those commands into Windows commands. That is a nice feature.

I heard about ms08-067 in 2016. I wonder what the atmosphere was like when it was first released. I didn't know it effected Windows 2008 and Vista too (although it looks to a lesser extent than Server 2003 and XP).

Ending

Its nice to see my CCNA paying off. I knew the /32 (one host only) syntax and how routing works enough to jump past these hurdles. Old me would've been stuck for hours and hours, totally unaware of what the problem was because I didn't have a networking background. OSINT can get me far too. I didn't have to engage in Google-Foo for this box but I may for future boxes.

Palo Alto for GNS3 CCDC Tutorial

Opening Hello fellow CCDC Competitors! Struggling to get a Palo-Alto VM? I know how you can get one! Email me at ASzampiasSWD@gmail.com. I'll tell you the steps to get a PA-VM for GNS3. Why am I giving this info to you? Wouldn't it make sense to hog the info to myself? Wouldn't my team have an advantage? There are have and have not universities when it comes to PaloAltos. I fell into the "have not" group. Our college didn't have access to PA-VMs and still doesn't. Even if PA Cybersecurity Academy is free, there is too much red tape. I can't change the outcome. I can only come up with this one solution. Another reason is Tri-C is a tryout team. I think its pretty unfair as a potential Firewall Admin I'm the only one with access. No one can challenge me unless they spend 2K for a PA-VM. It becomes a rich-person only position. I have a leftover PA-VM from 2018 I promised not to share. I couldn't share that with my challengers. But I f...

Trace Labs Global Missing Persons CTF V

Trace Labs CTF V TraceLabs hosted the Global Missing Persons CTF V event on July 11, 2020. My team //synergy got 64th place out of 190 teams. Introduction This was my first Trace Labs CTF. I captained a team. The good thing about being a captain is you can control who is on the team. My rules were: Must have sock puppet accounts ready. Must have a VPN. Writing out this is a competitive team where we work the entire 6 hours. I was worried about a future team member spamming submissions and disqualifying the team. I thought my requirements would eliminate people who weren't serious. The team hit 4 members Friday evening pretty quickly. Notes My laptop was too slow for this event. My virtual machine froze and I had to restart. Restarting means I have to login to my accounts again. I'll use my desktop next time. The team used Slack and Trello. Our strategy was to research a person and rotate every hour. This strategy broke after 1 rotation. Some missin...

Release of CCDC ISE Manager Website

I worked on the ISE (Inject Scoring Engine) website from 2017 to 2019. I made it to encourage teams to follow a merit-based, open admission tryout format. I identified a problem and made a solution for it. Problem: Call for Merit and Fairness on CCDC Rosters Solution: Github Project Solution: How to run a Team After Tri-C was finished with 2017 Midwest Wildcards I used httrack to grap the Inject PDF files. I didn't grap just the files, but the entire front-end code of the website. If you created the HTML and CSS of the original ISE website, tell me your name so I can give you credit! My goal was to make an almost-replica of the original. The database and back-end code is all guessing by me. I used a LAMP stack because I believe the original website is built on that. I did some fingerprinting and found the "ccdcadmin1" website was hosted on Apache and PHP. If you notice any bugs or errors let me know. If you want a feature added let me know. I will be working ...
