Watch Hackers Use a Drone-Mounted Laser to Control Malware Through a Scanner

Researchers in Israel have shown off a novel technique that would allow attackers to wirelessly command devices using a laser light, bypassing so-called air gaps.

The attack works by using a light source in the vicinity of the scanner to signal commands through the scanner to malware. The technique can be used to erase important files on a computer or network before an important meeting, trigger ransomware to encrypt files and systems, or launch a logic bomb already planted on a network to shut down computers or do something else. The attack could even conceivably be used against industrial control systems to shut down processes on so-called "air-gapped" networks, which aren't directly connected to the internet
