As with all HackTheBox machines I started with an nmap scan which identified port 80 was open and running nostromo 1.

HackTheBox Traverxec

While searching for some information on nostromo, pretty much the first search result was about a known vulnerability. I quickly found an exploit for it here. The exploit is basically a directory traversal vulnerability with remote command execution, hence the box name Traverxec.

Using the above exploit script I poked around the box and found an. Hoping those were the credentials to login via SSH I tried doing that, but no. Apparently they were for something else so I went back to poking in the box.

At this point it started to get a little cumbersome to use the above exploit script for every command, so I used it to make a reverse Netcat shell to my machine:. For the next part I had to look closely at the nhttpd file where I found the. Something was amiss though, as I had execute rights on that folder, so I could cd into it but not run ls on it.

After looking at the usual files. This worked, and I was able to use ls here and find a backup file. This backup file contained a private SSH keyfile which I transferred to my host machine and cracked with john.

Finally I had a pair of credentials to SSH into the machine and grab the user. Looking up the command journalctl on GTFObin revealed how one could escape the current environment and get a shell with!

Missing one simple detail might result into countless hours of wasteful searching and mashing of the keyboard :. Visiting If we do anything which is very suspicious bruteforce attack the login cough coughthe firewall might block us and render our future attempts useless.

Choosing the standard enumeration approach after trying default pfSense login credentials, I start out with gobuster. Main goal is to find hidden directories. Took some time to inspect all of the directories to no avail.

Extensions such as. Lazy sysadmins often leave files laying around. What a shame, right? As you can see now, we get 2 new options - changelog. Good news in this one! It mentions that 2 out of 3 vulnerabilities have been patched. That means that 1 vulnerability can still be exploited!

And for that a metasploit module exists. So we simply use this to get our foothold shell as www-data :. Doing enumeration we can see that only one other user exists on the system. We need to escalate to that first. When taking a look at the Nostromo configuration we find an interesting option enabled:. At the very end the homedirs are enabled.

We can simply look which files are stored there with our existing shell:. We copy that locally to our attacking machine. The private key is encrypted, so we brute-force the password.

A medium rated machine which consits of Oracle DB exploitation. The products itself are free and can be downloaded rather easily, however the updates are paid.

What does that mean? Many vulnerabilities and even more shells! Unfortunately due to nature of this box being heavily based around Oracle exploitation, I have no other choice. Well, at least in such a short period of time. If you want to exploit the machine with previously mentioned tools you need to set up the drivers yourself.

I attached few links below to help you with what is needed. Notice that port 80 - Microsoft IIS httpd 8. Just note it down, it will be useful later on.

Doing some enumeration I find out that this particular version of Oracle listener is vulnerable to remote TNS poisoning. How does it work Oracle users connect to a database through a listener. The listener forwards all their data to the actual database. This causes traffic to be load balanced evenly distributed between the 2 listeners. If lucky, some of the traffic goes through the malicious listener where an attacker can capture data login details.

More about it can be read here in greater detail. Unfortunately for us, this is just a lab machine. A MITM attack is not going to yield useful results there are no users to login. Moving on…. The Oracle install itself seems to be pretty well patched up. What else do we have then?

But since this date, HTB flags are dynamic and different for every user, so is not possible for us to maintain this kind of system. So from now we will accept only password protected challenges and retired machines that machine write-ups don't need password. It is totally forbidden to unprotect remove the password and distribute the pdf files of active machines, if we detect any misuse will be reported immediately to the HTB admins.

Anyway, all the authors of the writeups of active machines in this repository are not responsible for the misuse that can be given to the corresponding documents. Please think that this is done to share techniques not for spoilers.

In this way, you will be added to our top contributors list see below and you will also receive an invitation link to an exclusive Telegram group where several hints not spoilers are discussed for the HacktheBox machines.

Please consider protecting the text of your writeup e. Of course, if someone leaks a writeup of an active machine it is not the responsibility of the author. If we detect someone who does it, they will immediately report to the HTB Staff so they can take the appropriate measures.

Hack the Box is a superb platform to learn pentesting, there are many challenges and machines of different levels and with each one you manage to pass you learn a new thing. But talking among ourselves we realized that many times there are several ways to get rooting a machine, get a flag That's why we created this repository, as a site to share different unofficial writeups to see different techniques and acquire even more knowledge.

That is our goal and our passion, to share to learn together. Some people have been distrustful because in this repository there are writeups of active machines, even knowing that absolutely each one of them is protected with the corresponding password root flag or challenge. But We did not want to give up this because we think the most interesting thing for a HTB player is to check other users' walkthroughs right after they get it, that is, not wait for weeks or months afterwards.

For this reason, we have asked the HTB admins and they have given us a pleasant surprise: in the future, they are going to add the ability for users to submit writeups directly to HTB which can automatically be unlocked after owning a machine. And also, they merge in all of the writeups from this github page. Simply great! Therefore it is a real pride that they have decided to include the functionality of this repo directly on their platform. When this is done, this Github will be migrated and will be inactive but with a pleasantly fulfilled mission.

You signed in with another tab or window.I've tried everything under the sun and this really helped, as you can see. Of course this was paired with a healthy diet and exercise and if it wasn't for a few birthday treats last week, I think the results would have been even better. I highly recommend it. Once you start seeing improvement in yourself, it makes you even more determined to work for what you want.

CANT WAIT TO START MY SECOND BATCH AGAIN Camille Amber JohnsonI've completed the 28 day SkinnyMint Teatox and just posted a review on my channel.

hackthebox ctf machine

Over the past month I've managed to get closer to my fitness goals for the summer :) Watch the video for before and after and more details.

The nice thing about this is that I didn't have to go on any specific diets, change my eating habits, or do any fancy workouts. I just drank my tea in the morning and every other night. I know my body still isn't the best but it's a good start to how I want my body to look. Christa CorbinI heard about Skinny Mint from the web. I was looking for a new detox tea because mine was just causing me to run to the bathroom every hour or so when I drank it. I looked through their Real Results page and I just knew I had to try it.

I've always lived a healthy life until I was diagnosed with Arthritis and my daily exercise and yoga became less frequent. I decided to turn my life around because I didn't like how my body looked anymore and I knew I needed and wanted to live a healthier life once again.

Not only did the Morning Boost give me energy it taste and smells just like berries. It helped soothe my unwanted cramping pains and discomfort that comes along with Mother Nature. It also helped me fall asleep too.

I'm less bloated and my skin has been clearing up miraculously. Everyone has been saying I looked good and I have this certain glow about me lately.

This is only the 14 day and look at the results. Imagine the 28 day. Thank you so much Skinny Mint. You guys have helped me on my road to a healthier life and I will continue to use this teatox.

I've been exercising my butt off and I'm just so happy with the results. I knew I had to do something right away to get back into my old body. I was determined and motivated by all the gorgeous women on Skinnymint. I loved the tea.

I just can't wait to achieve my goal now. Still got a long way to go but I'll definitely be ordering another teatox soon. Kayla RosanelliSo I don't usually post pictures like this, but I promised I would post before and after pictures for my Skinny Mint Teatox trial. The top two are 28 days ago and the bottom two are from this morning.

I must clarify that while using the daytime and night time Teatox, I was trying to eat as clean as possible and working out regularly. Im not one to advertise but I would highly recommend this Skinny Mint!!. I am very happy with the results so far.

My fitness journey has only just begun.The eight-event campaign wraps up this week with the RSM Classic in Saint Simons Island, Georgia. At first glance, past editions of the tournament (formerly the McGladrey) tout winning scores hovering around 15 under. While that figure seemingly falls in line with other PGA Tour contests, Sea Island's Seaside coursewhere three of the four tournament rounds are heldweighs in as a par 70.

The southern property is very conducive to low scores, and the players have taken advantage of the lowered defenses. What's facilitated past success at the RSM Classic. Simple: getting it done around the dance floors. Last year's winner, Mackenzie Hughes, paced the field with a 1. That runner-ups Billy Horschel, Camilo Villegas, Henrik Norlander and Blayne Barber all turned in similarly solid efforts with the flat stick show this is one of the few events where "drive for show, putt for dough" holds true.

The professor, however, tends to favor a more aggregated approach in his picks. Kisner is a safe and smart pick, winning the event in 2016 with a T-4 in 2015 further boosting his case. Kisner hasn't made an appearance this fall, but did turn in a strong display at the Tour Championship (T-3) and played an integral part in the American blowout at Liberty National. But there are a few picks that raise some eyebrows.

Though Zach Johnson is a Saint Simons native, his outings at this event are mostly forgettable, missing the cut four times in seven tries. His best finish, a T-12, came in 2010. Johnson has been good this fall (T-13 at the Safeway Open, T-23 last week) and does have the short-game dexterity to thrive. Nevertheless, the iffy track record gives us pause.

As does Brandt Snedeker. Not only has Sea Island been unkind to Sneds (best finish is a T-32 in three events), but the veteran is making his first appearance since June, recovering from a bizarre, scary chest injury. Worse, Snedeker has undergone swing changes to address the ailment. Admitting he's not 100 percent, Snedeker is one of our stay-aways this weekend. In terms of likes, Brian Harman tops our expert's list.

Mentioned above, putting prowess will be key, an attribute that certainly applies to Harman.

The 30-year-old lead the tour in total putting last season, and ranked fifth in the sg: putting. Throw in two top 10s this autumn, Harman's a sound bet for a high finish. Same goes for Webb Simpson. Open champ has finished T-12 or better in three of five appearances here, and has two top 20s in the early season.

Though he ranked 32nd in overall putting last year, his around-the-green output (14th in strokes gained, first in scrambling from the rough, fifth in sand saves) shows he has the game to excel at Sea Island.

He's not exactly a sleeper pick, yet Simpson's popularity shouldn't keep you from picking him in your lineup. Check out the projections from the professor and expert, and play with the tool below to make your own picks for the 2017 RSM Classic.

By Joel BeallAmazingly, the fall season is already coming to a close. This paper reports an analysis of the accuracy of predictions of structural disorder received as part of the CASP5 experiment. Six groups made predictions of disorder. The predictions of the four most active groups have been compared with the experimental results, in terms of the sensitivity and specificity of the methods.

All four methods succeed in detecting over half the disordered residues in the targets, with a generally low rate of over-prediction. Two of the methods perform significantly better when the structure of a related protein is available. There is a trade-off between the fraction of disordered residues detected and the extent of over-prediction, and groups have adopted different compromises in this respect.
