Worth Reading: Hackers use drones and lasers to bypass air gap

When hackers infect computers with malware, they generally communicate with their code over the internet via a command-and-control server. But firewalls and intrusion detection systems can block communication going to and from suspicious domains and IP addresses. To bypass these normal detection methods, researchers in Israel have devised a novel way to communicate covertly with malware. The technique uses a flatbed scanner as the gateway through which an attacker can send commands to their malware on a victim’s network. —Motherboard
