We’ve all heard the saying “there is no delete button on the Internet,” but we secretly hope that when we take that unflattering photo off Facebook it’s gone for good. Well, attendees at the Automation Conference & Expo last week saw for themselves that that’s not the case. A presentation by a Certified Ethical Hacker (CEH), showed the audience how easy it is to resuscitate an old “deleted” MySpace account—pictures and all.

While that may seem trivial in today’s world of cyber threats, it was just one example by the presenter—who must remain anonymous as he is part of InfraGard, a collaboration between the FBI and the private sector to protect critical infrastructure. To make the information relevant to the audience, the CEH, using a hacker search engine called Shodan, was able to show a communications layer exploit that captured MQTT discussions between devices running on the Internet, ranging from soda machines to industrial valves.
