  • How hackers can cause physical damage to bridgesHelp Net Security

    In this Help Net Security video, Daniel Dos Santos, Head of Security Research at Forescout, talks about recent research, which has revealed how attackers can move laterally between vulnerable networks and devices found at the controller level of critical infrastructure. This would allow them to damage assets such as movable bridges physically. This lateral movement lets attackers access industrial control systems and cross often-overlooked security perimeters to cause physical damage. From sensors that measure and … More →
