New denial of service attack involves simultaneous strikes from large
number of remote machines
Further evidence of a new type denial of service (DoS) attacks with
unparalleled potential for causing havoc has been uncovered by
Internet Security Systems (ISS).
The attack involves co-ordinating a simultaneous DoS strike from an
unusually large number of compromised and remotely controlled
machines. ISS has issued an alert warning that a number of high
capacity networks have already been subjected to this radical new
type of onslaught.
This new approach to attacking a network was uncovered at the
National Information Systems Security Conference in the US. Now,
however, there is more evidence of how significant the approach is
becoming.
The ISS alert describes the attack in uncompromising terms, calling
it "more powerful than any previous DoS attack observed on the
Internet," and adding that "ISS considers this attack as a high risk
since it can potentially impact a wide number of organisations. It
has proven to be successful and is difficult to defend against."

One professional security consultant, Ian Johnston-Bryden of Oceanus
security says that although this isn't a ground-breaking discovery,
it does illustrate an important direction because it makes it far
more difficult trace an attack efficiently. "It's certainly quite
easy to put this sort of thing together," he says. "But it is very
difficult to be completely sure that it is actually a denial of
service attack. I'm fairly sure it's going to be used much more for
political attacks on Web sites. In HM government this is something
that they are becoming increasingly concerned about."
