It should be noted that BlackICE Defender, a competitive product, does precisely the same thing if one clicks on the "AdvICE" button. Since the attack information displayed by the program's graphical interface is quite brief (there's more in the log files, but only sophisticated users will know how to find and read them), users are strongly motivated to click the button. I do not know whether the URLs sent by either product are being used to gather statistics on the frequency of attacks or as a means of piracy detection. They certainly could be, if the vendors had a mind to do so. --Brett Glass At 12:40 AM 2/25/2000 , Andrew Daviel wrote: >ZoneAlarm by zonelabs.com can export possibly sensitive data if >the "More Info" button is clicked from an alert. > >ZoneAlarm is a personal dynamic firewall for Windows 9x/NT. >When a rule is triggered (typically an inbound connection to >an unregistered or alarmed service) an alert box appears with a brief >description of the event and a button labelled "More Info".
