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. And guess what? Your room thermostat is demanding $300 in Bitcoins to regain its control. Congratulations, Your Thermostat has been Hacked! This is not just a hypothetical scenario; this is exactly what Ken Munro and Andrew Tierney of UK-based security firm Pen Test Partners have demonstrated at the DEFCON 24 security conference in Las Vegas last Saturday. Two white hat hackers recently showed off the first proof-of-concept (PoC) ransomware that infects a smart thermostat. Ransomware is an infamous piece of malware that has been known for locking up comput

An air-gapped computer system isolated from the Internet and other computers that are connected to external networks believes to be the most secure computers on the planet -- Yeah?? You need to think again before calling them 'safe'. A group of Israeli security researchers at the Cyber Security Labs from Ben Gurion University have found a new technique to hack ultra-secure air-gapped computers and retrieve data using only heat emissions and a computer's built-in thermal sensors. WHAT IS AIR-GAPPED COMPUTERS ? Air-gapped computers or systems are considered to be the most secure and safest computer systems. These systems are isolated from the Internet or any other commuters that are connected to the Internet or external network. Air-gapped systems are used in situations that demand high security because it's very difficult to siphon data from these systems, as it requires a physical access to the machine which is possible by using removable device such as a US
