Could your HDMI cable be a gateway for hackers? This question highlights an alarming reality in our increasingly digital world. HDMI cables, which connect various devices such as TVs, computers, and gaming consoles, are often perceived as simple connectors. However, they harbor significant vulnerabilities that can jeopardize our data security. Recent research has unveiled that these cables can inadvertently leak sensitive information through electromagnetic emissions, making them an unexpected target for cybercriminals. The phenomenon, known as TEMPEST, allows hackers to capture and decode these emissions to reconstruct what is displayed on your screen, with accuracy rates reaching up to 70%. This revelation emphasizes the need for heightened cybersecurity awareness when using everyday technology, as these vulnerabilities can lead to serious breaches of privacy and security.
