"Potential Distributed Denial of Service (DDoS) Attacks"
17 September 2001
The National Infrastructure Protection Center (NIPC) expects an
Distributed Denial of Service (DDoS) attacks. NIPC Advisory 01-020,
"Increased Cyber Awareness" dated September 14, 2001 warned of
vigilante hacking activity against organizations associated with the
perceived perpetrators of the September 11, 2001 terror attacks.
On September 12, 2001, a group of hackers named the Dispatchers
had already begun network operations against information
components such as routers. The Dispatchers stated they were
communications and finance infrastructures. They also predicted that
would be prepared for increased operations on or about Tuesday,
There is the opportunity for significant collateral damage to any
network and telecommunications infrastructure that does not have
countermeasures in place. The Dispatchers claim to have over 1,000
under their control for the attacks. It is likely that the attackers
mask their operations by using the IP addresses and pirated systems of
uninvolved third parties.
System administrators are encouraged to check their systems for zombie
software and ensure they institute best practices such as ingress and
filtering. The NIPC has made available the "Find DDoS" tool to
