Matthew learns Pentesting/EH

 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....

 Now this exploit for my rig was a little hard just because I do not have the most RAM and it required slightly more than the others. So I took less screenshots  This again is the same step as the others. Figuring out what ports were available  Here we are using "ffuf" again Now I believe this is the first time we used "dnsrecon" And here we add the dns to our machine so we can perform the attack Follow me at  LinkedIn  or  Twitter

 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.  Remember feel free to contact me on  LinkedIn  or  Twitter

 This was a fairly simple exercise. Important parts not in the pictures are Lists are always in brackets "[]" and numbering starts at 0. So be mindful your first item in a list is 0 not 1  Feel free to contact me on  LinkedIn  or  Twitter

 This lesson was short and sweet and easy to understand. So, a Boolean expression is just an expression of true and false. Which my understanding is that it comes in handy later on when you call functions like, if such and such is true then do blah. Please find me on  LinkedIn  or  Twitter

Today was pretty fun. It was a simple lesson but one I think will be handy. I am a huge math geek. My 3 year old and I randomly add the numbers we see on the street and he is getting to the point he can do his multplication tables up to 10 already. So learning that python can do math by scripting it makes sense but I can also see how that might be handy in the future when I am writing more advanced scripts for vulnerabilities in a system. As I am sure I have said pentesting isnt where I want to stop. I want to go full red team and overall I want to be good at as much in cyber as possible. I mean the goal is to do as much good with this knowledge as possible so learning scripting on all angles would make me more effective but anyways, we did some simple scripting for math and it sounded like we will get to the more advanced in a later lesson.  Check it out and if you know of some simple scripts I can add to my math knowledge let me know I would love to give it a try. Feel free to re...

 I first want to apologize for the couple days I have been off. I had some personal things to take care of and then lost everything from my PEH course so had to get everything back in order.  So today we learned to script in bash. We were running an IP sweep which I had another little symbol slip past me. I think in the first 3 photos you can see it. If you see it leave a comment. I did end up getting it fixed and running it.  This picture here ^ I actually tried to run the program getting an error message This ^ is where I figured out my mistake and fixed it  And this ^ was how we cleaned it up a little more to make it function and look a little better I had fun with this one. I have played around in Linux and ran a few commands, but this is the first time I scripted something and actually ran it.  I would love to hear from you guys with any constructive feedback or maybe some other scripts I should try as a newbie.  You can also connect with me on LinkedI...

 Ok so today's is one of those things where I am not proud it took so long but I am proud that I finally came up with a solution.  On pentesterlab I have been trying for a couple hours to use burp repeater to do a file upload injection but for some reason it wouldn't work. So, I decided to switch to using OWASP Zap to try on that tool and it didn't work.  I started getting frustrated and decided I would step back and try and think about a different way to do things. Then I realized all I was trying to do was rename a file from test.php to test.php3 and upload it and repeater was just stopping me from having to rewrite the file on my desktop. SO, I figured I had already written the php code, so I went in copied what was in the file and created a new file with the test.php3 name and uploaded it the regular way. Now I know this is not the way pentesterlab has it set up BUT.... I would argue this. I spent probably 3 hours trying to do it their way. And time and again in the l...

 So, I have stated that when I am stuck, I take a step back for a few minutes, but I wanted to explain that I don't just go and do nothing.  True there are times when I go play with my son or cook my family lunch, or whatever. But for me my learning right now is to a point that I feel like I need it for my sanity. But on the same hand when I get stuck on something that, maybe I think I shouldn't it drives me nuts, LOL. I have high expectations of myself, so I can get hard on myself when I don't immediately get something. But back to the topic. Let's take this morning for example, I was working through what should have been an easy task on  PentesterLab , but one of my computers is down so I am working on the one I never installed VIM on, which this exercise called for. I thought no problem how hard can it be to install VIM on Windows. And I was correct it wasn't that hard. I started going through the task and it wasn't working, and I couldn't tell why. So, I...

 So today I was working on the exercise "Server Side Template Injection 01" on  Pentesterlab . I try and do all my exercises on both laptops at the same time. This does 2 thing for me; 1) I get to see how it works on 2 different systems a windows in the Edge browser and a Chromebook in the Chrome browser. I got this idea after I had to switch on one exercise and noticed subtle differences. While this seems like common sense for some reason it was something I never thought about before. So from that point forward I thought more exposure is good so I solve all the exercises on both.  2) I can solve on one while watching the walk through video on the other. For me it is easier and clicks in my head better if I don't have to watch, pause, execute, watch, pause, execute. But back to my point while watching the video I kept getting frustrated cause I thought I was doing exactly what he was doing. I switched back and forth between computers, restarted 3x's, stepped away and ...

 So let me first say thank you for joining me in this journey. I wanted to take a minute to introduce myself. First and foremost, I am not an English major, and this blog will not be perfect grammar. This will  act more like a journal entry style blog.  My name is Matthew and I am an Army veteran, a former barber, former motorcycle mechanic, a dad, husband, and recently I am finding a love for cyber red team activities. I have been interested in cyber passively for some time, but never ally took it seriously. Then when we were quarantined for COVID I ended up losing my barbering business and kinda was thrown for a loop. For the better part of 2 decades barbering has been all I have known. Heck in most circles no one even knew my name, I was simply "The Barber." Now the next part is something that I am only going to share because it is relevant to my decision to explore cyber security as a career.  As a veteran I have been diagnosed, like many, with PTSD. Being quaran...
