Defcon 20 - Dan Tentler - "Drinking from the caffeine firehose we know as shodan" ▶ this video Warning - watching this may readjust your faith in humanity. Telnet is just the tip of the iceberg. edit: (15:42) "Econolite [stoplights] listening on telnet. There are intersections [with] stoplights; you can telnet into them and put them in 'test mode'[sic], and the warning says, 'Don't do this, you could kill people!'"

It's much worse than just passive webcams. Some devices which were never meant to be connected to the internet are out there. Stoplights? HVAC Systems? Carwashes? Ice Rinks? POWER PLANTS? Yes! ▶ this video EDIT: I looked at his more recent talk from last November ... the situation has not improved "115 batshit stupid things you can put on the internet in as fast as I can go by Dan Tentler" link Featuring Spanish Chicken Controls

It's both amazing and scary that this kind of vulnerability is fairly common. Check out this great talk given at Defcon ( ▶ this video ) to get an idea of the magnitude. These are systems that do not require any kind of tampering or credentials. Most times credentials are given to you in a prompt!
