From Clive Akass’ “Storm worm ‘making millions a day’” (Personal Computer World: 11 February 2008):
The people behind the Storm worm are making millions of pounds a day by using it to generate revenue, according to IBM’s principal web security strategist.
Joshua Corman, of IBM Internet Security Systems, said that in the past it had been assumed that web security attacks were essential ego driven. But now attackers fell in three camps.
‘I call them my three Ps, profit, politics and prestige,’ he said during a debate at a NetEvents forum in Barcelona.
The Storm worm, which had been around about a year, had been a tremendous financial success because it created a botnet of compromised machines that could be used to launch profitable spam attacks.
Not only do the criminals get money simply for sending out the spam in much more quantity than could be sent by a single machine but they get a cut of any business done off the spam.
