Hi all security experts!
I have a Win98SE machine running Kerio Personal Firewall 2.1.5 and blackICE IDS. I am behind a Belkin Gateway Router with NAT and firewall enabled. When I run a Shields UP 'common ports scan', port 80 is found to be open! A few months ago, when I last checked, all ports were stealthed. A virus/trojan scan with AVP 3.5, Sophos AV 3.72, Inoculate IT 4.5, eSafe AV, F-Prot for DOS, TDS-3, The Cleaner and Trend Housecall all show negative results. Inspection of all running processes, msconfig startup, and autoexec.bat contents show nothing suspicious. I have uninstalled personal web server. The Kerio Firewall Status and ‘netstat –an’ show no suspicious connections. (see below) Active Connections Proto Local Address Foreign Address State TCP 0.0.0.0:44334 0.0.0.0:0 LISTENING TCP 0.0.0.0:44334 0.0.0.0:0 LISTENING TCP 127.0.0.1:8080 0.0.0.0:0 LISTENING TCP 169.254.246.190:137 0.0.0.0:0 LISTENING TCP 169.254.246.190:138 0.0.0.0:0 LISTENING TCP 169.254.246.190:139 0.0.0.0:0 LISTENING TCP 192.168.2.2:137 0.0.0.0:0 LISTENING TCP 192.168.2.2:138 0.0.0.0:0 LISTENING TCP 192.168.2.2:139 0.0.0.0:0 LISTENING UDP 0.0.0.0:44334 *:* UDP 169.254.246.190:137 *:* UDP 169.254.246.190:138 *:* UDP 192.168.2.2:137 *:* UDP 192.168.2.2:138 *:* Remote administration and DMZ is disabled on my router. A spyware check with AdAware and SpyBot S&D (all updated) shows no spyware infestation. What could be causing port 80 to be open, and how could I stealth it? Thanks in advance. Richard Richard H |

When I run a Shields UP 'common ports scan', port It's probably port 80 on your router (remote admin). When you run external scans against yourself you are running them against your router (Your public IP address) Not against your actual PC. I can confirm your port 80 is showing as open but I'm unable to connect to it. Cheers ST -- ..: http://www.security-forums.com :. Share your knowledge It's a way to achieve Immortality. |

On some you can specify that port 80 is only open to your local network. This is generally a good idea and prevents anyone from the internet administering your router. It may be that that is the way yours is already configured if an external scan does not show the port as being open. Connect to it and see what it says. Then read your router manual carefully. -- Jim Watt http://www.gibnet.com |

Remote/web administration is disabled on my router, and Shields UP still reports port80 as open. Could someone have hacked into my router and changed the settings so it looks to me that remote admin is disabled, but really it is enabled? The router settings are protected by a non-default password, and i have never enabled remote administation before. -----BEGIN PGP SIGNATURE----- Version: PGP 8.0 iQA/AwUBPzzD0iYncAS5ivfOEQK6VgCfR3D8Hw0q7ZZbLLRj87MN3Y 8vp+IAnRP6 RQodoAGJDzEh2hmWR+4yMA6+ =XFUi -----END PGP SIGNATURE----- |
