A friend sent me this article from Wired magazine and I recommend everyone read it – we need to know what's out there, and what malicious developers are capable of.
Attack of the Bots
"The latest threat to the Net: autonomous software programs that combine forces to perpetrate mayhem, fraud, and espionage on a global scale. How one company fought the new Internet mafia – and lost."
The question I have is, if it's so insidious and almost un-winnable a battle, what are our options? The thing I used to say to frustrated users was "get a Mac." It's still the most immune machine out there at present!
