I was once at a conference on security and a guy from NASA told the story of how they wrote their own virus and put it on a floppy labeled something about sex, naked women or something like that, and within a few days it was on almost every computer in the place.... I have never understood the fascination with naked people and porn and such that most women appear to have . . . . lol

It's people in dead-end, low-wage, low-morale work whose job it is to open files sent in by random people and punch in invoices, hours worked, or orders into systems are the perfect target for this kind of targeting. Or clueless guys who get the email, "Here's those pictures of that beautiful girl I promised you, " perhaps spoofed to look like a buddy's email. Or gullible people. Or people too rushed who get caught by accidental oversight. > What are the odds that the recipient actually had a recent > conversation about a file with a person chosen at random by a bot to put in the "From" > field of that email?

But divide those long odds by the cost - zero - to send the message, and the potential earnings - bazillions - if you can compromise yet another machine to add to the botnet. And this assumes a random, phishing attack, and not a spear-phishing attack specifically targeting a user. If you want the clerk in a accounting to open a file, you spoof an email from the VP by name citing discussions with her boss, again by name, that "he was the one to get this project done, and it needed to be done ASAP!" > This is what I mean about risk-benefit analysis.

And again, the economics are such that it is nearly free to send a million of these emails, and anyone you catch puts money in your pocket. > If you just tell people not to open any attachment that they don't > know exactly what it is, you've achieved the same level of security > without inconveniencing anybody or spending any extra money. > And if you tell people they should always have protected sex, AIDS infections would stop tomorrow. In theory, theory and practice have the same outcome.
