In an era where digital connectivity is paramount, HDMI cables are ubiquitous, linking devices across offices and conference rooms. However, the security implications of these common connections are often overlooked. Recent studies, particularly one from Universidad de la República in Uruguay, have highlighted serious vulnerabilities associated with HDMI cables, revealing that they can inadvertently leak sensitive information. Hackers can exploit the electromagnetic emissions generated during data transmission, reconstructing what is displayed on screens with disturbing accuracy. This means that confidential data, including passwords and private communications, could be intercepted without the victim's knowledge, posing a significant risk to business security.
