Security researchers at Ben-Gurion University of the Negev (BGU) were able to use infrared (IR) light to control the behavior of security cameras infected with malware. The technique was detailed in a research paper published on Monday.
The technique is called “aIR-Jumper,” and it will work with both professional and home security cameras, according to press release from BGU. It could affect LED doorbells as well, as they can also detect IR light, the release noted.
Using IR light, the researchers were able to achieve optical communication between air-gapped internal networks that acted bidirectionally, meaning messages could be sent and received. Air-gapped computers are isolated from the internet, the release said, and are often considered to be more secure than their connected counterparts.
