Fix for Open Port 113 in BlackICE |
| Home The Perl Game 21 Calendar Vulnerabilities/Exploits: |
Problem: Blackice has a little known vounerability from the first version all the way to latest version (2.9.Car as of writing) It allows port probes from 113 through. This can be a major security risk to all users because all a hacker need's to do is scan port 113 and even a computer that doesn't respond to ping commands or scan's on any other port(s) will show port 113 as "open" or "listening."
Contacting ISS:
Solution:
There are two solutions: The first one I rcomend the most. 2.) Once BlackICE Defender Opens go to the top and select: Tools>Advanced Firewall Settings 3.) After the Advanced Firewall Settings Box has opened click on the one that says 113 under Ports. 4.) Next Click Delete 5.) Click OK 6.) Click Close
Thats It your done! |
This can leave you vounerable to a wide range of attacks and scans. Under normal circumstances when a firewall is running it should drop the packet that was sent to that port (113 in this case). Instead with blackice defender it leats that packet go by and the computer responds with either Closed or Open. This will make the hacker scaning you think that if everything is stealthed except port 113 then the computer has to be running Blackice Defender!! Then they will probably know of many holes in Blackice and break into your system. The hardest part for a hacker is Identifying what kind of computer the person is hacking and what kind of protection you have (If any). The rest after that is easy. The sad part of this is I am in high school and figured this out!
