Today I wanted to see where I was at, and I've learned that I've got quite a long way to go - but I don't feel like this is discouraging.How to connect & Access with efficacesweat.fun network
I may be even more excited than I was when I decided to start this journey. The nice part about the VIP access now is that you can spin up any retired box on demand and work on it as you please - this is a new feature that was added and was a deciding factor for me. This was mostly a day of getting stuck, finding hints, learning how the various processes work, finding more hints, getting stuck again, learning more, and around and around.
It made me build some methodology to how I attack these boxes, what to do first, where to check for vulnerabilities, how not to get stuck down a rabbit hole.
I started getting a little but frustrated, but finally I found a remote code execution vulnerability and I was able to compile a python reverse backdoor I had built into an exe from Kali and upload it to the target - started my listener that I also built and waited for the shell to pop And when it did, I was hooked.
Occasionally you may want to run Nmap with the -p- flag, this is to scan all ports, this should be done in the background as it can take a bit of time.
The normal scan does the common ones, but if someone is running a service on a non-standard port, it could be missed with the normal scan.
Run version checks on all services, check them on exploit-db or searchsploit command line tool for exploit-db - run a search through msf to see if there are any vulnerabilities for the versions you see.
SMB shares are a common thing in these boxes port, you can run a few commands here to get some info on these:. This is assuming that anonymous login is enabled on the box. I need to do more research on this, but from what I've read, it looks like you're using the DNS host of the system to look for zone transfer records which will spit out the subdomains available: dig axfr [HostIP] [hostname] The [hostname] portion is why you'll need to have your hosts file set up.
I believe there's also a way to add the server as a nameserver on your box so that the subdomains will resolve but I have more to look into on that.
Thinking about it now, if this is being used on HTB and you don't have a DNS server on your box with those entries, the subdomain dictionary attack will likely return nothing. I've got a long way to go. This will be a checklist of sorts for me or anyone else to reference for future boxes.
Obviously we want to start with a scan first: nmap -sC -sV -oN [host]. Anyway, this one was long and all over the place. Hope it helps someone out. Journey to Security. Share this.Now, what can we do with it? How can a tutorial of unplayable machines be useful? So: go on on Bashed, that's a CTF box, relatively easy, but confusing at the same time. The first step as usual is to start a recon doing an nmap -A -sV That's it. Half of the challenge is completed But now the hardest part So let's list some user's privileges with command sudo -l.
As visible we can execute commands while switching to another user, in this case scriptmanager without providing a password.
With this knowledge, it's time to start a Reverse Shellfor instance the first step is on our attacking machine to start a listener by nc -lvnpnow our netcat instance is still waiting for incoming connection. On the other side under our phpbash. Don't forget to replace XXX.
XXX whit your IP and check that the connection port matches the netcat listener port. Once you have it done, start a simple Reverse Shell to our machine as scriptmanager. Great, here we are. Now let's grant this bash a little bit of functionality by running python -c 'import pty; pty. You can notice 2 files, one owned by the scriptmanager user us now and one owned by the root.
Looking at their content we had. Seems like the test. After having spent a lot of time by searching where it's called, I've tried to modify the file I have looked again for something useful in the machine, but when I was back to the script, it was restored, so I've thought someone must have changed it back.
HackTheBox.eu - 3 Month Update
Long story short, I've edited it again, but late in time it was restored again Then I had an idea: the responsible had to be something like a cronjob or some other script. So now it's time to link another reverse shell as above. On my attacking machine I've launched another netcat instance with nc -lvnpand on scriptmanager reverse shell, I've written another file called shell.
But not satisfied I wanna know were those scripts were recalled No results for your search, try something different. Claudio Quaglia. Recommended for you. Hacking Reverse Shell Cheat Sheet. Hacking VulnHub - ch4inrulz: 1. Hacking VulnHub - Wakanda: 1 Writeup.Not so long ago, I achieved a milestone in my penetration testing career.
Hack The Box is an online platform allowing you to test your penetration testing skills and exchange ideas and methodologies with thousands of people in the security field. The idea is relatively simple, Hack The Box is a platform where every so often, a new virtual machine or a challenge is released. Every machine or challenge is intentionally vulnerable, and every machine or challenge has a respective difficulty. I created an account while I graduated university, about 2 years ago, but because my first job did not require any pentesting skills, I let my account lay dormant for a good long while.
That is until about a year ago when I decided I wanted to have a full-time job in cyber security. In this blog post I will try to condense some tips and tricks on how I went on to become the highest-ranked hack the box player of Belgium. My personal background is system engineering. I did not learn any offsec skills in school. I personally learned most of my skills and my methodology from him.
He has a very clear approach in his videos and is easy to listen too. The Cybermentor is the second one on my list. Granted, I have only learnt from his existence not that long ago while I was prepping for my OSCP certification, but the dude is pretty awesome. In my personal opinion, these 2 form a very nice duo that will groom you from zero to hero in no time.
Some boxes will be very easy for you, some will be very hard. Hack The box tries to give each box a ranking, but my personal experience tells me that some boxes that are labelled easy, are actually incredibly hard. The boxes where I had to spend hours, days and sometimes even weeks, are the boxes that will teach you valuable lessons.
When I tackle a Box, I always try to have some kind of passive enumeration going in the background. Computers are more efficient at multitasking than humans are. You never know when you might find that diamond in the dirt.
This might seem obvious, but in our infosec community, new tools spawn almost every…single…. Therefore, it is important that after your enumeration is done, you start to look for the proper tooling for the attack vectors you have in mind.
It often happened to me that I did not have knowledge of certain tools, which made my exploitation process needlessly complex, longer and sometimes even near impossible. Yep, even if you have used the tool for years, you will probably still get surprised by the functionality that some tools have. This will, again, save you a couple of hours. Unless you are stubborn and think you know it all, in that case … carry on … but you are gonna need that man page sooner or later.
Unless you have a VIP subscription for Hack The Box, chances are that there are multiple other people trying to hack the same machine as you. More often than not, this means that there are going to be players on your box that I like to call machine gunners, firing off every exploit in Metasploit in the hopes one will hit its mark.
Fortunately, this means that sometimes boxes misbehave and will not react the way they should to certain exploits.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

March in Other Security Certifications. I did it a bit on a whim but am glad I did! The lab also features segregated networks that will require you to carefully route through the network to achieve different goals.
The ultimate goal is to achieve perimeter level access into the network, work your way through the network, and ultimately hack your way into Domain Admin. There are flags to obtain along the way. The lab will challenge you to learn new techniques, learn tools you may not be used to using, and to learn how to think more like a red team member. In my experience, I was able to fully hack the environment with a 1 month ticket aside from the ROP challenge I'd highly recommend this lab for those that would like to attack a more modern network!
March Not fishing for spoilers, but they mention 16 flags. Is that roughly 16 machines in that environment? I'm just looking to gauge the size of that network. How would you compare the difficulty, scope, or realism between rastalabs and going through the comparable parts of the OSCP? So, there are actually 17 flags.
HackTheBox - Bashed Writeup
But admittedly, the main goal is domain admin. The flags are basically the mechanism in use to be able to allow it to exist in the HTB framework. Some of the flags are on the attack path, some are not. I am not a redteamer by trade, but I can say that the domain environment presented in this lab is much more secure than most of the customers I work with. In that regard, its a pretty decent model of what a secure domain could look like in the real world.
It's hard to compare the two. The OSCP lab is great at teaching certain lessons.I was about to start another box on hackthebox. It was 90 days ago today that I found out about this wonderful site and decided to give it a shot. So after about 12 weekend days and a handful of late nights after work I have now owned user and system on 13 systems and a handful of challenges. Originally I had hoped to have all 20 active machines completed at this time but as usual life and work got in the way, in addition to that after the first few systems I had decided to not just do the challenges but to make instructional videos showing others how I completed them so I could share my process with others which to no surprise has ended up taking up large amounts of my already limited free time.
I was inspired by people like IppSec and others who have shared their knowledge via YouTube videos and instructional write-ups. I felt this was important because no matter how experienced you are we are all constantly learning and there are always new tools and techniques that you can learn and that requires that people share their knowledge so the community can learn from each other. So after 3 months I can say that this site is definitely fun and helps computer security enthusiasts and practitioners practice skills in a very close to real-world environment without the threat of legal troubles.
The fact the site is free makes it even more impressive, and if you have the coin I highly recommend their VIP plans which get you access to retired systems and access to less crowded VIP servers. So what are you waiting for? Hop on over there and get started by hacking yourself an invite code! Below you will find the 3 videos that I have been able to post I have the other 10 ready and waiting for when the systems retire I'll also be releasing some of the tools I have written very soon and will make a post about them when they are ready.
