A New Threat to CSP Networks â The Impending âBlack Storm”>
Nexus Guard
A new cyber threat, coined a âBlack Stormâ attack, could potentially wreak havoc on communications service provider (CSP) networks. While DDoS amplification attacks rely on DNS servers or other similar open services to interrupt connectivity, a Black Storm attack can leverage any device connected to the Internet. Researchers caution that the volume from one Black Storm attack could terminate medium to large-sized enterprises in a clean sweep and severely cripple a large-scale CSP network.

Hackers can achieve Black Storm attacks more easily than amplification attacks, which could quickly dominate the cyberworld. Black Storm attacks could be manifested by hackers employing a BlackNurse attack in a reflective manner (rBlackNurse attacks). By generating spoofed UDP requests to CSP devicesâ closed UDP portsâa reflection of the ping replies returned to the CSP network ping sources in BlackNurse attacksâthe devices respond with destination port unreachable responses. As more devices continue to respond to the spoofed IP source, the volume of responses completely overwhelms the target CSP network and creates the Black Storm attack.
