Apparently one or more friends of mine have been infected with Netsky worm variants, like this one:
Each day, I get a number of email messages from this person or persons with the worm attached. I would really like to let them know they're infected... But I don't know how.
I've tried to correlate the arrival time of the messages with friends I know are online, but have not been able to do so. I've also contacted some of my more technically innocent friends directly, but their systems were OK. As I can see the originating IP address in the email headers, I've tried "NET SEND ip_address contact_me_message", not really expecting that it would work... and it didn't :-(
I don't really want to send a bulk email to everyone I know. So, I'd like to ask if anyone has any idea how I might contact another person, if all I have is their IP address?
