He was referring not to the log viewer executing something, but transmission of data to the server containing the URL (stored in their logs). A common spammer trick, used also in more legit ways, is to send an email with an image in it. The image is actually a CGI script that takes a parameter, logs it, then kicks out an image. "Webbugs" tend to be 1px square, and possibly transparent. Using this can automate testing if email addresses are valid (by sending each address a different unique tracking URL). -- Bill Weiss _______________________________________________ Full-Disclosure - We believe in it.
