+#####  2) Stack Buffer Overflows 
+
+These are the most common binary exploits, they are there because of insecure functions that do not set a limit to user input, allowing the user to overwrite other memory registers.

+#####  Assembly x86_64 
+
+As i hit the shellcode buffer overflow binary challenges, i realized that i needed assembly skills, so this is a simple introduction to modern intel Assembly for the x86_64 (64bits) architecture. We make use of the [syscalls](https://chromium.googlesource.com/chromiumos/docs/+/HEAD/constants/syscalls.md#x86_64-64_bit) used to communicate with the Linux Kernel:
