Ever wonder why the S in SD cards stands for Secure? Well, it turns out that it is possible to read and/or write protect these cards by software using specific commands. As you might expect, this process isn’t as "secure" as the name implies leading to multiple issues. This talk will present some of these features and the vulnerabilities discovered while poking at cards from various manufacturers. The equipment used in this talk is quite easily attainable allowing for easy replication and learning about these attacks.

DEF CON (also written as DEFCON, Defcon or DC) is a hacker convention held annually in Las Vegas, Nevada. The first DEF CON took place in June 1993 and today many attendees at DEF CON include computer security professionals, journalists, lawyers, federal government employees, security researchers, students, and hackers with a general interest in software, computer architecture, hardware modification, conference badges, and anything else that can be "hacked". The event consists of several tracks of speakers about computer- and hacking-related subjects, as well as cyber-security challenges and competitions (known as hacking wargames). Contests held during the event are extremely varied, and can range from creating the longest Wi-Fi connection to finding the most effective way to cool a beer in the Nevada heat.
