Ransomware Hits The Internet Of Things: Smart Thermostats Hacked

First-Ever Ransomware For Smart Thermostat is Here — It's Hot!

Swati Khandelwal | August 8, 2016

Internet of Things (IoT) is the latest buzz in the world of technology, but they are much easier to hack than you think.
Until now we have heard many scary stories of hacking IoT devices, but how realistic is the threat?
Just think of a scenario where you enter in your house, and it's sweltering, but when you head on to check the temperature of your thermostat, you find out that it has been locked to 99 degrees.

[Andrew] Tierney [from Pen Test Partners] said that it was able to take the firmware, and it had everything he needed to make it run ransomware. “It heats to 99 degrees, and asks for a PIN to unlock which changes every 30 seconds,” he said. “We put an IRC botnet on it, and the executable dials into the channel and uses the MAC address as the identifier, and you need to pay one Bitcoin to unlick.”
