Over the past 7 months, I've been delving deep into the realms of Windows exploit development. My journey has taken me through the intricacies of reverse engineering, crafting custom shellcode, and tackling complex topics such as stack overflow, SEH Overflow, DEP and ASLR bypass, format string specifier vulnerabilities, etc. I'm grateful for my dedication and curiosity about cybersecurity, and the resilience I've developed along the way. I'm more than pleased to have finally earned this badge and to move forward with the invaluable experience and knowledge gained.

Coming from a "bluey" background I could not imagine that offensive tasks could be this fun to me. Still, everything that I learned will be very helpful in my malware reverse engineer path. At this point I do want to thanks OffSec for constantly maintaining and improving their training system, making the process as smooth as possible and feeling supported all the time, with great challenges and environment to test your learning and play around.
