Actually blackICE defender version 1.8.2.6 does not send anything "sensitive" in nature. What I captured was such: 1) 3 way handshake 2) GET <A HREF="http://advice.networkice.com/advice/Intrusions/<number">http://advice.networkice.com/advice/Intrusions/<number</A>> 3) Error 302 ("Object Moved") Location: <same as above but add "/" after <number> > 4) GET <A HREF="http://advice.networkice.com/advice/Intrusions/<number">http://advice.networkice.com/advice/Intrusions/<number</A>>/ 5) page is sent. Can you tell me which version you're running?

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". When this is clicked a URL is passed to the user's Web browser sending information to Zone Labs' server for more detailed explanation. Currently (version 2.0.26) the information passed includes: Source Address and Port Destination Address and Port Operating system version Firewall version Whether the connection was blocked The lock status of the firewall All this information is sent in clear as an HTTP GET request (port 80). It could possibly be seen on the Internet in transit or in proxy logs,
and
may include information about machines on an internal network inside a corporate firewall. The request itself could be blocked by ZoneAlarm, but it is likely that the setting for the Web browser would allow it to
access
the external network (Internet). It is fairly simple to edit the .EXE file to disable this feature, or to redirect it to a local server. (IMO the benefits from using the product outweigh the risks of this data leak....) Andrew Daviel Vancouver Webpages etc.Thanks, John Lampe
