Corero Network Security (CNS: LN), a leader in on-premises Distributed Denial of Service (DDoS) Defense Systems for enterprises, data centers and hosting providers, named its list of 2011’s top five DDoS attacks. Corero’s findings show an increase in newer, intelligent application-layer DDoS attacks that are extremely difficult to identify “in the cloud,” and often go undetected until it is too late. Corero also found an uptick in attacks against corporations by “hacktivists” DDoS-ing sites for political and ideological motives, rather than financial gain. Attacks against Mastercard, Visa, Sony, PayPal and the CIA top Corero’s list.
“The cat-and-mouse game between IT administrators, criminals and hacktivists has intensified in 2011 as the number of application-layer DDoS attacks has exploded. Coupled with an increase in political and ideological hacktivism, companies have to be extremely diligent in identifying and combating attempts to disable their websites, steal proprietary information and to deface their Web applications, ” said Mike Paquette, chief strategy officer, Corero Network Security.
Corero’s 2011 Top 5 DDoS list includes the following high-profile attacks.
