Ka'Von Wooden loved trains. The 15-year-old had an encyclopedic knowledge of New York City's subway system and dreamed of becoming a train operator. Instead, on a December morning in 2022, Ka'Von died after he climbed to the roof of a moving J train in Brooklyn and then fell onto the tracks as it headed onto the Williamsburg Bridge. He is one of more than a dozen New Yorkers, many young boys, who have been killed or badly injured after falling off speeding trains.
The US Cybersecurity and Infrastructure Security Agency (CISA) issued CVE-2025-1727, specifying weak authentication in the end-of-train to head-of-train linking protocol, enabling attackers to input braking commands.
