Cobalt Strike - Cyber Threat Intelligence

These indicators were reported, collected, and generated during the VulDB CTI analysis of the actor known as Cobalt Strike. The activity monitoring correlates data from social media, forums, chat rooms, and darknet markets. It helps to determine associated actors, specific activities, expected intentions, emerging research, and ongoing attacks. Our unique predictive model uses big data to forecast activities and their characteristics.

Live data and more analysis capabilities are available at https://vuldb.com/?actor.cobalt_strike
