Talk Title :

Finding and Exploiting Critical Bugs in TLS Libraries used by “Smart” UPS Devices


Abstract :

UPS devices are becoming “Smart”, connected devices that can be controlled by the Cloud. This offers advanced features, but also exposes an attack surface through which attackers may be able to remotely take over the power lifeline of an organization. This talk will detail a number of zero-click preauthentication vulnerabilities we’ve discovered in a prominent UPS vendor. In addition we will explore the physical threats involved with controlling a sensitive battery-powered device, and demo an attack that can literally “blow up”.
