Video jacking: why you have to be much more vigilant with HDMI security than with USB security
0We must be careful where we connect our cell phones. If it is already easy to gain access to our devices over the Internet, providing physical access is even worse. For years, experts have been warning about the risks of using public USB devices to charge the cell phone. This is known as juice jacking. Today we are going to talk about an even more dangerous variant: video jacking.
While the USB allows data to be transferred, the HDMI connection allows an image to be duplicated. Through this function, attackers can record the screen of their phone and see everything that is written or touched on it, be it passwords, account numbers, photos, private texts, or emails. If with the USB port it is possible to install malware, with the HDMI connection the risks are even greater.
