The end of 2018 saw a rash of cyberattacks mounted by way of networked printers. In one notable incident, as reported by Kaspersky, a hacker targeted 50,000 printers and caused them to print a message supporting a YouTuber named PewDiePie. According to Kaspersky, the hacker had utilized Shodan, a search engine for devices, and found no fewer than 800,000 vulnerable printers from which to choose. This story, and many others like it, should alarm anyone tasked with cyber security duties. The ubiquitous printer can be a dangerous, overlooked attack surface.
