Subject: Steve Gibson's December/2000 News from GRC.COM ... _________________________________________________________________ Significant Security Vulnerability Revealed in Almost ALL PC Personal Software Firewalls NEW Firewall "LeakTest" freeware from me! _________________________________________________________________ I have not written to you for five months because I haven't had any really BIG news (until now) and I never want my eMail to be irrelevant or annoying to you. I am committed to NEVER abusing your trust. Today's BIG news is the release of my latest freeware: 'LeakTest' LeakTest is used to check your firewall's vulnerability to an extremely common and easily exploited design flaw revealed by this test. At this time, EVERY FIREWALL BUT ONE is vulnerable to this danger, and some are more vulnerable than others. (Due to the strength of its design, the FREE ZoneAlarm firewall, produced by ZoneLabs, Inc., can not be penetrated by this test.) ZoneLabs, Inc. Our new LeakTest page, accessible through the link below and also from our site's home page, provides the whole story and the means to download my new and compact (27k byte) LeakTest freeware: LeakTest Page The LeakTest page also contains links to our very active public newsgroup forum (grc.leaktest) at grc.com. This group is discussing the LeakTest issue and comparing firewall behavior. You can quickly find any help or further clarifications you may need within this group. Other News: 1. NANOPROBE: I have been working on an incredibly exciting new Internet security testing technology, known as NanoProbe. It is not yet completed, but you will certainly be among the first to know when it is. The following page contains background: NanoProbe Page 2. FILE DOWNLOADER SPYING: The last note I sent to you revealed the privacy breaches inherent in many popular file download accelerators. Thanks to YOUR SUPPORT on this issue, every vendor of those programs immediately updated their software to remove this spying behavior. THANK YOU for working with me to let them know that this behavior was NOT ALL RIGHT with you! 3. OPTOUT and AD-AWARE: I decided that my long-term plans for OptOut were wrong: Rather than scanning the user's system for Spyware, I should check the user's system for its firewall's VULNERABILITY to known AND unknown spyware. This is the initiative I am now launching with LeakTest. But there is STILL a very pressing need for a high-quality spyware scanner. I can recommend -- without reservation -- the EXCELLENT, comprehensive, and completely FREE Spyware scanning and removal tool by LavaSoft: 'Ad-Aware' Ad-Aware 4. FUTURE MAIL FROM ME: Many of our subscribers have worried about not hearing from me every month (fearing that they were missing my notes). Others have said that they want to know what's going on (like with my NanoProbe development) even if it's not "BIG news". With my next mailing, I will create a means for you to tell me and "Opt-In" if you want monthly news no matter whether it's BIG or small. Until then I am not going to bother you until I have something I KNOW you will want to know. _________________________________________________________________ Thank you for your time. I hope this has been useful to you. Steve Gibson. GRC Website
