Pass the Cookie and Pivot to the Clouds
Web Applications and Services use cookies to authenticate sessions and users. An adversary can pivot from a compromised host to Web Applications and Internet Services by stealing authentication cookies from browsers and related processes. At the same time this technique bypasses most multi-factor authentication protocols.
The reason for this is that the final authentication token that the attacker steals is issued after all factors have been validated. Many users persist cookies that are valid for an extended period of time, even if the web application is not actively used.
