Arbor Networks Security Engineering and Response Team (ASERT) has discovered a denial-of-service tool specifically designed to target the U.S. government s healthcare enrollment marketplace, Healthcare.gov. The tool reportedly performs layer seven requests to get to the webpage, alternating between healthcare.gov and that same website s contact us page. The application is available for download from a number of sources and is being distributed on social media networks as well.
