CowPatty Stage 3 Introduction:     Cowpatty being a tool that related to some of my interests I wanted to take a deeper look into how it works. At the start I understood the basics, feed it a 4-way handshake, SSID name and a dictionary file and it would spit out its best guess of the SSID. While Cowpatty has the ability to 'guess' the SSID's password, its only effective / used to audit networks that have poor / common / default passwords. Interestingly enough in this Defcon video titled "Weaponizing Your Pets: The War Kitteh and the Denial of Service Dog"  - Provided he made his warkitteh sniff for packets and save them, he could attempt to hash SSID+handshake to get passcodes. He got quite the list of SSIDs, Some WEP which I dont think is a setting on new routers (hopefully).  I do not condone Weaponizing you pets or strapping batteries to them, do not attempt. However, it was neat! Since CowPatty has to match keys it has to got through a large d...

Compiled C Lab Let's start by writing the hello world. then with this saved we can run the compiler with the Flags specified                     gcc -g -O0 -fno-builtin hello.c Looking at the objdump header file for our program Objdump -f We see that: Were using an x86 platform File Format is in ELF ( Executable and Linkable Format) We can look at the specific selections of this output file by using objdump with -d flag which disassemble sections containing code Objdump -d This is our main! We can see the function call to printf with callq on line 5. The argument was moved into the register on line 4. - Static gcc -g -O0 -fno-builtin -static hello.c -o hellostatic objdump -s hellostatic The file was huge, when read wouldn't fit in the whole window! This is due to the .static flag.  It causes the libraries to be inclu...
