Cyber War
professionals are watching with great interest the progress of the Storm
botnet. This is the largest botnet ever seen, and it is acting like something
out of a science fiction story. The
Storm computer virus had been spreading since early in the year, grabbing
control of PCs around the world. By August, Storm had infected nearly two
million computers with a secret program that turned those PCs into unwilling
slaves (or "zombies") of those controlling this network (or botnet) of
computers. Many of you may have noticed a lot of recent spam directing you to
look at an online greeting card, or accompanied by pdf files. That was Storm,
the largest single spam campaign ever. When you try to look at the PDF file,
Storm secretly takes over your computer. Anti-virus programs are disabled and
Storm tries very hard to hide itself. All it wants to do is use your Internet
connection to send spam, or other types of malicious data.
To avoid the police
(especially the U.S. FBI), many botherders (those who operate botnets) are
usually in countries without an extradition treaty with the United States,
where nearly half the zombie PCs are. Criminal gangs are increasingly active in
producing things like Storm, and, in the case of China, so are government Cyber
War operations. It's unclear who is controlling the two million Storm zombies,
but it's becoming clear what Storm is up to. It has been launching attacks at web
sites involved in stopping or investigating Storm. This involves transmitting
huge quantities of bogus messages ,that shut down targeted web sites (this is a
DDOS, or distributed denial or service attack). The Storm botherders are also
advertising their botnet as available for the usual illegal activities (various
types of spam).
But the most alarming aspect
of all this is the sheer size of the Storm botnet. It's quite possible that
it's not all one, huge, two million PC botnet. There may be several owners, who
simply used variations of the basic Storm virus (which showed up last February,
using as a lure the promise of news about the huge Winter storms then lashing
Europe, and thus got its name.)
Police and Cyber War
organizations are certainly trying to track down who controls Storm, mainly in
self-defense. A botnet that large could shut down major sites, or large chunks
of the Internet itself. The Storm is the Internet equivalent of a nuclear
weapon, and no one is sure who controls it.
