The number of people needed to launch a successful denial-of-service 
attack has been overestimated by the press, according to the European 
Network and Information Security Agency.

Attacks such as those by pro-Wikileaks groups need significantly fewer 
participants than has been reported, the European Network and 
Information Security Agency (Enisa) said on Tuesday. Visa was taken down 
by a distributed denial-of-service (DDoS) attack from roughly 500 
machines, Ulf Bergstrom, Enisa's spokesman, told ZDNet UK on Thursday.

"An attack can be constituted by much fewer machines [than was thought], 
and that is quite concerning and quite an important point to make," 
Bergstrom said.

DDoS attacks against Wikileaks, Visa, PayPal and various government 
sites all demonstrated that "size doesn't matter: the number of 
computers used in the attacks was relatively small (in the hundreds). 
Some press reports claim over six times the real number, which is 
indicative of the unreliability of information about botnets", Enisa 
wrote in a statement on Wednesday.
