Computer Lab

Researchers from Ben-Gurion University of the Negev in Israel have figured out a way to steal information from an isolated computer not connected to the internet.

By taking advantage of small changes in color and brightness on LCD monitors, bad actors could use cameras to "see through" the ordinary screen's content, revealing vulnerable data.

Although this kind of attack would be complicated to pull off, it's an example of ways that researchers are trying to stay one step ahead of the hackers.

Hackers know some insidious ways to siphon data, so scientists have to think up as many scenarios as possible to keep abreast of the bad actors. Mordechai Guri, head of research and development for the Advanced Cyber-Security Research Lab at Ben-Gurion University of the Negev in Israel, is on the case.
