Abstract: A method and system for communicating emergency information about computer security threats together with mitigating actions that may be performed depending on the configuration of each computer. A secure package that includes a message regarding a threat and that potentially includes a script including actions to mitigate the threat is created. The secure package is published to make it available for downloading. The alert package is downloaded by a set of computers, and the message and the script (if any) are extracted. Stats and other feedback from the computers that download the alert package may be provided.
