The United States rail system harbors significant security flaws that could potentially empower attackers to remotely engage train brakes with low-cost devices. This alarming vulnerability, identified over a decade ago, has only recently garnered attention. Despite intensified protective measures adopted by the rail industry, a substantial portion of the technology remains susceptible to exploitation. The Cybersecurity and Infrastructure Security Agency (CISA) of the United States has issued a stern warning, urging rail associations to promptly address this critical issue.
