Functions in Python

 Here are my notes from the functions lesson of the PEH. I think this was a fairly easy lesson to follow along with. My biggest take away I think is the importance of the indentation. As well as the fact that you can have single or multiple parameters.

And as a reminder the '#' on the right-hand side of the code are my notes for later. I have always like keeping shorthand reminders that call back things rather than long drawn-out notes. But if you need any clarification please comment or message me on my social medias and I will try and elaborate.

LLMNR

Here we learn a little about LLMNR. So here is a description of the attack. I think the key here is that it provides the hash. These days anytime you can get a hash it's a win. Even if its long and complex, hash cracking tools are a 3 second google search.  I like graphics like this cause to be honest, even if I know how to attack it I am not always sure how to mitigate what I am doing. Its why I like learning what is behind the scenes. In the next few posts, I am going to show some mitigation techniques the course brought up and the reason for that is it really helped me start to think about how to mitigate. Again, I will not be sharing everything and if you want to learn more, please go check out  TCM Security . This has really been a great course to get my brain thinking in ways to help businesses.  And here are their recommendations for mitigation. And this is just to get your brain in the mode of mitigation. Remember we are doing this to help businesses not just to d...

More mitigations

Image
 So like I said we are going over mitigations and I grabbed a couple slides and while this is not everything, I grabbed ones that helped to spark a thought process and understand how mitigation can be performed. Now we started with SMB Relay because we were told its one of the most exploited vulnerabilities. Really until this slide I was thinking "if it's such a known vulnerability why is it still being used?" And seeing this slide with the pros and cons made me realize certain things need to be used and our job as security professionals can't be just to shut down everything that can be exploited but rather make things as safe as possible so that our companies can still be as productive as possible while being as safe as possible. Now I always thought I knew strong passwords but in taking this course I found out just how easy password cracking is. So, 14 or more characters and make it complex.  Capital, Lowercase, Numbers, Special Characters, stay away from common wor...

Overwrite and BadChars

Image
 I wrote a script for Bad chars and show how I overwrite the program. This is all leading up to finding the right module and then gaining shellcode. Exploit Development is defiantly something I want to take some more time to get to know. I plan on going through these videos at least one more time.  So a couple things to remember is take out "\x00" and make sure you wrap it in "()" Here is the first code I wrote And here is the correct code. Anyone catch the mistake? Thats right line 9 I forgot to change.  Now remember like with all the lessons before we are running both vulnserver and immunity debugger as admin. Attaching vulnserver  to Immunity Debugger and pressing play. The goal is to overflow the buffer space and through the EBP (Extended Base Pointer) and into the EIP (Extended Base Pointer Instructional Pointer). Which is where we will be placing the malicious code.  And as you can see it is now paused meaning we gained overflow and crashed the machine....
