Security researchers have discovered a new way hackers can steal sensitive information like passwords. This includes hiding over HDMI cables, which is an important development for computer users.

The technique, detailed in a recent study by researchers at the Universidad de la Repubblica in Uruguay, uses artificial intelligence to decode electromagnetic emissions from HDMI connections and reconstruct what appears on a computer screen. .

The researchers found that they could capture the electromagnetic radiation emitted by HDMI cables using readily available software-defined radio equipment. By applying deep learning algorithms to analyze these captured signals, they can reconstruct text and images from computer displays with up to 70% accuracy.

“This level of precision is often sufficient for an attacker to decipher passwords, sensitive data, or encrypted communications displayed on a screen,” explained lead researcher Federico Larroca. The team’s AI system has improved over the previous competition. earing Efforts, reduces the character’s damage rate by more than 60% points.

While likewise Weaknesses Known for older CRT monitors, the complex digital signaling used by modern HDMI connections was thought to make such attacks impractical. This new research shows that AI can overcome these barriers, potentially putting millions of computer users at risk.

The good news is that executing such an attack requires significant technical expertise and specialized equipment. The researchers believe that the average home user is unlikely to be targeted. However, they warn that government agencies or corporations may be at greater risk from sophisticated attackers.

“It is likely that similar techniques are already being used by advanced hackers or state-level actors,” Larroca warned. “An attacker could potentially capture HDMI output from outside a building using equipment hidden in a nearby vehicle.”

To protect against this risk, cybersecurity experts recommend being aware of your surroundings when working with sensitive information, especially near windows or in public spaces. Using encrypted connections and avoiding displaying passwords on external monitors connected via HDMI can also help reduce risks.

Researchers have made open source. Their results To help improve defense measures. As the cybersecurity landscape continues to evolve, this discovery serves as a reminder of the importance of being vigilant about emerging threats to digital privacy and security.
