I didn't double check rules on posting external link here but I didn't see this resource on AR anywhere, if staff has any issues with this post please delete. I totally forgot about this awesome tutorial site until recently so wanted to share for those who are interested. This particular link is was a HUGE help for me when starting to try to understand disassembly. Its focus is on Ollydbg but its information is good for any disassembler such as IDA. No prior experience is necessary as it starts from such a basic level anyone can go from knowing absolutely nothing about x86/ARM to really understanding how to identify functions and how to manipulate stack, etc. Lenas Reversing for Newbies Side note: just go thru the whole site is you have interest in coding in general, its an amazing resource. Enjoy!
