For presidential candidate Donald Trump, the greatest threat to our cybersecurity may very well be a "400-pound" guy.

During Monday night's presidential debate, candidates began to discuss who might have been responsible for this summer's DNC hack. While Russia was initially blamed, Trump claimed that it could have been anyone, including the Chinese or someone "sitting on their bed who weighs 400 pounds."

It's unclear who, exactly, Trump was referring to when he mentioned this mysterious "400-pound" man, or if he entirely understood the consequences of his statement.

So according to Trump hacking of DNC was done by some random 400-lb guy. Intel community says it was Russia. Who ya gonna believe? — Max Boot (@MaxBoot) September 27, 2016

Trump plans to build a wall between the United States and Mexico, but can he build a firewall against sedentary 400-pound guys?
