This is Cybersecurity Awareness Month, a time when vulnerabilities in cybersecurity are highlighted due to their potential for serious consequences. To celebrate, Bugcrowd has launched a new series called Unsolved Cyber Mysteries, which retells the stories of everyday people affected by extraordinary breaches and data leaks. The first episode focuses on the 1987 Max Headroom signal hijacking, where an unknown person in a mask appeared on TV screens for several minutes, causing widespread confusion among viewers, engineers, and broadcasters. The incident was eventually thwarted by changing the studio-to-transmitter frequency used to transmit the broadcast signal, but not before the hacker had shown himself dancing and making threatening gestures. The episode will explore the motivations behind the attack, its impact, and a breakdown of how it happened.
