Raphael Arkelian, the OT/IOT cybersecurity manager at Accenture, joins the Nexus Podcast to discuss his research into Operation Grim Beeper, the name given to a two-day attack in 2024 in the Middle East where explosives were introduced into pagers and walkie-talkies favored by Hezbollah. The explosions injured more than 1500 and killed dozens. Raphael’s research looks at several aspects of this attack and shares lessons and security gaps that can be applied across the OT and supply chain ecosystems.
