This joint guide, Understanding and Responding to Distributed Denial-Of-Service Attacks, addresses the specific needs and challenges faced by organizations in defending against DDoS attacks. The guidance now includes detailed insight into three different types of DDoS techniques:
Volumetric, attacks aiming to consume available bandwidth.
Protocol, attacks which exploit vulnerabilities in network protocols.
Application, attacks targeting vulnerabilities in specific applications or running services.

All attempts were obviated by MAV and process detections, but boy-howdy, did they try!
A new Denial-of-Service (DoS) attack targets application-layer protocols that draw on the User Datagram Protocol (UDP) for end-to-end communication.

Early this February, Fortinet released an advisory for an "out-of-bounds write vulnerability" that could lead to remote code execution. The issue affected the SSL VPN component of their FortiGate network appliance and was potentially already being exploited in the wild. In this post we detail the steps we took to identify the patched vulnerability and produce a working exploit.
