OverTheWire[.com] Leviathan Walkthrough - JUST HINT, NO SPOILERS

PASSWORDS for each level are stored in /etc/leviathan_pass/leviathanX

Leviathan
The Leviathan game is about basic debug/hack/trace binary files in linux, and how to exploit them.
The main tool you will be using here is ltrace, so read & google about it. Use it in ALL levels except Level 0, even if i don't mention it.

Another important note is that most of the files have the "s" flag in their permissions, meaning they run in elevated privileges, and that's important to understand the solutions. Go read about that too.


Level 0: Bookmarks

bookmarks.html is the file chrome creates when you export all your bookmarks, people can save sensitive info there.


Level 1: Introduction to "ltrace"

Time to use "ltrace".


Level 2: Exploiting "cat"

Most of the tutorials out there are out of date, exploiting symbolic links, and exploit "cat".
You can still exploit "cat", but it won't make you solve the level, they make a little trick so you will be forced to do the real exploit.

The real exploit here is that there is absolute no validation on the input, so you can give any input you would like, as long as there is a valid path of that.

Remember. valid path.

Technically, just in case, i have a full spoiler about that here. But again, we want you to get it alone and reading what can be a path in linux, and what characters you can add to different kind of objects that a path is built from, you'll get it.


Level 3: ltrace

Not really sure what the difference between this one and Level 1.


Level 4: binary 

Find your favorite tool, piece of code or an online tool to finish the job.
I learned "./bin | perl -lape '$_=pack"(B8)*",@F'".


Level 5: Symbolic Link

Go learn what is a symbolic link in linux, and how to create and use one.


Level 6: Brute force

for loop can be written like "for i in {0000..9999}"


THANK ALOT for OverTheWire.com team.
THANK ALOT for all the bloggers out there that helped me solve this.

OverTheWire[.com] Natas Walkthrough - JUST HINT, NO SPOILERS

game portal: http://overthewire.org/wargames/natas/ PASSWORDS for each level are stored in /etc/natas_webpass/natasX I made this walkthrough for people like me, i needed some help, but didnt want the spoiler, so here i will give you all the information needed to pass each level, yet not the solution. For levels needed custom web request i made a different post for powershell and javascript  with how-to's, since is a piece of learning for itself, and also for those of us that play at work and have only powershell at their hands. Although its not a complete spoiler there, its quite most of the solution so try yourself 1st. Natas The Natas game is from basic to advances web hacking. Every few levels is about whole new exploitation (with some harder ones doing comeback later), so a lot of learning. If you're new, you're the reason i am writing so much even for the 1st level, just please google EVERY topic you see, since in the following levels i assume you know the ...

Asp.Net Ending Response options, Response.End() vs CompleteRequest()

this blog is for any1 who get the ThreadAbortException when caling Response.End(), and then tried the other options such as HttpContext.Current.ApplicationInstance.CompleteRequest() and found out that there was no replacement. i'll start with the bottom line: if you want to stop right now your response and send it as is you dont have any other option other than Response.End(), period and it's the right thing to throw that EX in that case. the answer is its because there is the "HTTP pipeline" and the "Asp.Net pipeline", and CompleteRequest() cuts the HTTP pipeline but not the Asp.Net one so everything that is from handlers forwars (including all page events) continues but your part, the asp one, stays in your hands so that no information will be lost, so ur suppose to manage your code currectly, since information lost is really a bad thing, although in most cases we use Response.End() we know what we are losing and we want it. see this short article ab...
