Reverse

~# cat Question

Try reversing this file? Can ya? I forgot the password to this file. Please find it for me?

FILE: ret.elf

This challenge was a straight forward reverse engineering task. Upon opening the ret file, it displayed numerous unreadable symbols. Thus, I utilized strings on the file to extract readable strings and grep to search for the stringpico within the extracted strings, which got me the flag.
