The VRT is excited to announce a revolutionary new module for the Snort Intrusion Detection System. The module will allow any of the systems running Snort to act as one of several pre-configured operating systems and applications. Using a special client, you can execute a variety of “attacks” on the system. The intended use of this is not to attract a mate, but instead is to be used on patch days. When patch day comes, no one will stand in your way, because you are the supreme blackhat.”]
