When Network Clocks Attack
In October 2013, Cisco TRAC discussed Network Time Protocol (NTP) as a possible vector for amplified distributed denial of service (DDoS) attacks. Litnet CERT has since revealed that their NTP servers were used in a denial of service (DoS) attack. Symantec also published information regarding an NTP amplification-based DDoS attack that occurred in December 2013. On December 7, 2013, a hackforums.net user posted an NTP amplification DDoS script to Pastebin. The NTP DDoS script is heavily obfuscated Perl, though the plain text at the top credits the "leaking" of the script to an individual who goes by the handle Starfall.

Meanwhile, Yahoo intimated a different timeframe for the attack, claiming “From December 31 to January 3 on our European sites, we served some […]
SecCon and the Limits of the Human Mind
One of the things I like best about Cisco’s focus on security is the internal SecCon conference we put on each year. It focuses on security threats, defenses, and innovation. Although I participate as a trainer, organizer, and reviewer, my favorite role this year was as an attendee. The conference theme, The State of the […]
Are Third Parties Your Greatest Weakness?
There are many advantages in outsourcing functions to specialist providers that can supply services at lower cost and with more functionality than could be supplied in-house. However, companies should be aware that when buying services, you may also be buying risk.
