1. Internet Root Servers Attacked
In the latest and particularly dramatic demonstration that no network is
safe from the perils of modern computing, Monday evening a
sophisticated, large-scale DDOS (distributed denial of service) attack
took on the Internet's 13 root servers. Of the 13 root servers,
responsible for handling the Internet's DNS (domain name system), only 4
or 5 took the hit (an onslaught of illegitimate service requests)
without denying service to legitimate traffic.

As the root server system is designed to maintain normal traffic with
just 4 or 5 of the servers functioning, users probably did not notice
the attack. Despite this built in service "buffer", a longer and more
powerful attack could have slowed traffic down to noticeable levels or
even worse.

The FBI among others is investigating the event and at this time no one
knows who may be behind this attack. A spokesman for UUNET, operator of
two of the 13 root servers said, "This could be someone just messing
around, but it could also be something much more serious. It's too soon
to say." There is also the danger that this was just a "test" strike, a
prelude to a more serious attack in the future.

The majority of DDoS attacks in which the computing power of many
computers is focused against an individual or a smaller number of
computers, are often perpetrated by hackers who use automated software
to scan millions of computers for known security holes. The computers
that are found to have the necessary vulnerabilities are usually owned
by unsuspecting, innocent home users who are unaware that their
computers are taking part in distributed denial of service attacks.

Offering a solution to DDoS attacks Alan Paller, research director at
the SANS Institute, a nonprofit security research and training group,
warns, "The only way stop such attacks is to fix the vulnerabilities on
the machines that ultimately get taken over and used to launch them.
There's no defense once the machines are under the attacker's control."
