Round 2 has started!

5 years, 2 months ago

Round 2, Bamboozling Binaries, is live! If you’re not already familiar with it, you should read up on buffer overflow and using gdb before you start your timers!

Finally, you might need a UNIX shell to run some of these binaries! For those on Macs and Linux, you can just open your terminal program. If you’re using Windows, you can use Cygwin, MinGW or even the c9 web shell service. If you need assistance setting these up, hop on by our irc channel and we’ll lend you a hand!
