About The Project Continuing from Arch Cloud Labs TrendNet 731BR router hacking blog post tearing apart firmware, we’ll now start poking at router hardware! The primary objective is to grow my skills in the embedded security domain for DEF CON’s IoT and Embedded Security Villages next year. This weekend’s project focused on a GL-AR750. I originally bought this router in 2017 as a travel router, and it has been collecting dust in my closet for quite some time.
