"[4] The final event was held on August 4, 2016 at the Paris Hotel & Conference Center in Las Vegas, Nevada within the 24th DEF CON hacker convention.
The Cyber Grand Challenge featured, however, a more standardized scoring and vulnerability-proving system: all exploits and patched binaries were submitted and evaluated by the referee infrastructure.
Races develop between criminals attempting to abuse vulnerabilities and analysts who assess, remediate, check, and deploy a patch before significant damage can be done.
[2][3] Devices such as smart televisions, wearable technologies, and high-end home appliances that are connected to the internet aren't always produced with security in mind and moreover utility systems, power grids, and traffic lights could be more susceptible to attacks, says the DARPA.
[8] Reducing external interaction to its base components (e.g., system calls for well-defined I/O, dynamic memory allocation, and a single source of randomness) simplified both modeling and securely running the binaries in isolation to observe their behavior.
Internal complexity was however unrestricted, with challenges going as far as implementing a particle physics simulator,[9] chess,[10] programming/scripting languages,[11][12] parsing of huge amounts of markup data,[13] vector graphics,[14] just-in-time compilation,[15] VMs,[16] etc.
