Spammers Adopt Stealth Tactics: Botnets

["Fergie" <fergdawg () netzero net>]

This is not news, of course -- I've just never heard of
BlackSpider Technologies, and was wondering which botnet
they're talking about here in this article?

Botnet controllers are switching to stealth tactics in a bid to avoid detection. Instead of mass mail-outs of spam and 
malicious code, they are adopting slower distribution tactics in a bid to avoid appearing on corporate security radars.

UK-based web security firm BlackSpider Technologies reports that one huge botnet, responsible for issuing 50m identical 
spam emails per day, compromises at least 150,000 distinct IP addresses. The use of a large number of machines - each 
sending out an average of 330 emails a day or around 40 per hour during the course of a working day - is a change from 
days of yore when a handful of compromised email servers would have been used to do the same job.
