The material is available to learn for free from HackerOne. Feel free to share and join the conversation on Twitter with hashtag hacker The Hacker CTF is composed of a series of levels, where you can learn to hack in a simulated real-world environment. In each level you're searching for a number of flags -- unique bits of data -- which you get by discovering and exploiting vulnerabilities. As you progress, you'll receive invitations to private programs on HackerOne, jump-starting your bounty hunting career.

O ut of curiosity q uestion is which one of these statements is evaluating to True either any or maybe both? Because OR operator.
Now the real start. Defining the query using LIKE operator so we can match a pattern of available valid password. The query matches character x if password contains it or not.
How do I find those with this. Well we have to use. The middle characters we found could be unsorted because adi characters are sorted and our payload list was sorted as well so it found in exact correct order. What if there were unsorted characters iad or maybe numbers or symbols anything! With underscores we can find any character on exact position but before that we need to know length of characters in a password.
To find the username associated with password nadia we need to find length of username too. Like Like. Like Liked by 1 person. I followed you step by step …. Hello, that worked for me.
But you have to adapt, as username and password is not the same than in the article. Thanks for that article, it is very didacticle, PALY. Thank you for the write-up. What tools were you using?I feel I am really close on a few of the challenges, but being new to the scene, it would be great to have a place to refer to instead of continually banging my head against the wall.
I would then be able to re-trace the steps it took to get to those solutions, or see if I was off by a simple encoded character or something. So, my question is, has anyone here completed those CTFs? I took a break from them for now and am using some other resources. I plan on going back to them in a few weeks. I will probably do a writeup with hints and possible solutions as long as they are okay with it.
The idea is awesome, could just use a little more support for the beginner side of the spectrum. Have you started working on the hints and solution yet? If so could you post a link to them. I am getting stuck on the easy ones, and I am not sure what I am missing. What resources are you using to learn? I have been keeping notes of how and what I have solved for the most part though.
I recommend joining the RedSec discord channel, lots of helpful and smart people. I can get you an invite if you need one. Then when you feel good about that one, move on. I started out with breadth first, which is nice, but a lot of programs have already had the low hanging fruit picked and that is all you will probably find with breadth and little depth. I read through both those books, and I only found half as many flags.
I tend to over complicate it, and I have been stuck on the easy levels for a while now. I tried some of the moderate levels, but have not found one there yet. I have been doing the same thing, I write down how I found them all, plus what I have tried, and any interesting finds that might lead some where. It takes time for sure. I just sent you a message with an invite link. Feel free to PM me anytime, my name is the same as it is here.
Could you get me an invite to the RedSec discord channel?

Thank you. I did solve the other easy and medium challenges including the ones you mentioned in your original post and this is the last one for me to solve plus the two hard ones which I havent looked at yet. Maybe you or someone else have some time to discuss the challenge, what I have tried so far and what else I could look into? Any further help or advice will be much appreciated. Hi there, would be nice if I also could get an invite to RedSec if you dont mind.
Greetings absoThemay I kindy ask for an invite. Sorry if this is more of a General Security Discussion topic. CSwiers December 9,pm 2.
They provide video lessons about every subject in the ctf series:.Hex dump of image is fetched. I used some other options —skip and —threads 10 there were some connection issues sqlmap was running very slow. Also -o for optimization. Like Like. Thank you bro.
Like Liked by 1 person. For faster data retrieval with sqlmap you can use method HEAD to avoid the render time that the server takes to make the image. This works because HEAD is allowed and you are only looking the header response to be Hope it makes sense :. There says the application is running on the uwsgi-ngnix-flask-docker-image What does it mean? Sure, the trick is basically just to use the SQL commit statement.
The albums table is also vulnerable. I wrote a short python script that helps with the injection with an example usage. Flag 0: eg. An environment variable will give you the third gem. I write a article about FLAG2. Those who want to know more about FLAG2 can check it. View at Medium.
Wonder where i am going wrong. Any advise would be highly appreciated as i am stuck on this for days.This challenge is on Moderate level and has 3 Flags to be discovered. As the information given, we know that the blog is written in PHP and PHP function include is some what useful for us.
Then, we have this comment box to submit comments. Conclude that, maybe XSS scripting does not work here. View the page source, we can see that line 19 is commented out. Seems like we can access the admin page through that URL ending.
Therefore, we are able to conclude this. Basically, the developer thought of having all 3 files and include them to save time and energy. Have you ever played jigsaw puzzle before? Not easy but cool! I try to put in my understanding into this. We can roughly conclude that we can run anything as long as enclose it inside the PHP tag. Since we know those, instead of access the file through URL. Why not print out the file instead.
