Nest of 13 million Virus infected Personal Computers busted

Authorities have smashed one of the world's biggest networks of
virus-infected computers - a data vacuum that stole credit cards and
online banking credentials from as many as 12.7 million poisoned PCs.
The "botnet" of infected computers included PCs inside more than half
of the Fortune 1,000 companies and more than 40 major banks, according
to investigators.
Spanish investigators, working with private computer-security firms,
have arrested the three alleged ringleaders of the so-called Mariposa
botnet, which appeared in December 2008 and grew into one of the
biggest weapons of cybercrime.
More arrests are expected soon in other countries.
Spanish authorities have planned a news conference for Wednesday in
Madrid.
The arrests are significant because the masterminds behind the biggest
botnets aren't often taken down.
And the story of investigators' hunt for them offers a rare glimpse at
the tactics used to trace the origin of computer crimes.
Also, the suspects go against the stereotype of genius programmers
often associated with cyber crime.
The suspects weren't brilliant hackers but had underworld contacts who
helped them build and operate the botnet, Cesar Lorenza, a captain with
Spain's Guardia Civil, which is investigating the case, told The
Associated Press.
Investigators were examining bank records and seized computers to
determine how much money the criminals made.
"They're not like these people from the Russian mafia or Eastern
European mafia who like to have sports cars and good watches and good
suits - the most frightening thing is they are normal people who are
earning a lot of money with cybercrime," Lorenza said.
The three suspects were described as Spanish citizens with no criminal
records.
They weren't named and their mug shots weren't released, which Lorenza
said is standard in Spain to protect the privacy of defendants.
They face up to six years in prison if convicted of hacking charges.
Authorities identified them by their internet handles and their ages:
netkairo, 31, jonyloleante, 30 and ostiator, 25.
Botnets are networks of infected PCs that have been hijacked from their
owners, often without their knowledge, and put into the control of
criminals.
Linked together, the machines supply an enormous amount of computing
power to spammers, identity thieves, and internet attackers.
The Mariposa botnet, which has been dismantled, was easily one of the
world's biggest. It spread to more than 190 countries, according to
researchers. It also appears to be far more sophisticated than the
botnet that was used to hack into Google Inc. and other companies in
the attack that led Google to threaten to pull out of China.
The researchers that helped take down Mariposa first started looking at
it in the spring of 2009.
Chris Davis, CEO of Ottawa-based Defence Intelligence, said he noticed
the infections when they appeared on networks of some of his firm's
clients, including pharmaceutical companies and banks.
It wasn't until several months later that he realised the infections
were part of something much bigger.
