Service Port Table
Service Ports Status Additional Information
FTP DATA 20 CLOSED This port has responded to our probes. This means that you are not running any application on this port, but it is still possible for someone to crash your computer through known TCP/IP stack vulnerabilities.
FTP 21 OPEN File Transfer Protocol is used to transfer files between computers. A misconfigured FTP server can allow an attacker to transfer files, trojan horses, and virus programs at will.
SSH 22 BLOCKED Secure Shell, a encrypted type of telnet. If misconfigured it can allow for brute-force attacks on your administration account.
TELNET 23 BLOCKED Telnet is used to remotely create a shell (dos prompt), this can allow an attacker to control your system as if he was sitting in front of it.
SMTP 25 OPEN SMTP is used to send email acrost the internet. This allows an attacker to verify user accounts on your system, send anonymous (spam) email, or even access files on your hard drive.
DNS 53 BLOCKED none
DDC 59 BLOCKED Used mainly by file transfer and chat programs.
FINGER 79 BLOCKED Finger offers information about who is currently logged in to your computer.
WEB 80 OPEN HTTP web services publish web pages. A misconfigured web server can not only offer an attacker needed information about his target, but it can allow for various security breaches.
POP3 110 BLOCKED Post Office Protocol is used to receive email. It can be used by attackers to create fake email addresses, execute programs, and even intercept your private email.
IDENT 113 BLOCKED Ident is often used for IRC (chat), but also provides information about your system and who is using it.
NetBIOS 139 BLOCKED NetBios is used to share files through your Network Neighborhood. If you are connected to the internet with this open, you could be sharing your whole hard drive with the world! This is a very dangerous port to have open.
HTTPS 443 BLOCKED Secure Web Servers are often used by banks and online vendors.
Server Message Block 445 BLOCKED In Windows 2000, Microsoft added the possibility to run SMB directly over TCP/IP, without the extra layer of NBT.
SOCKS PROXY 1080 BLOCKED Socks Proxy is an internet proxy service, many IRC servers will not allow you to log in if you are running an unsecured socks proxy.
SOURCE PORT 3131 BLOCKED This is the port you are using to communicate to our Web Server. A firewall that uses Stateful Packet Inspection will show a 'BLOCKED' result for this port.
WEB PROXY 8080 BLOCKED HTTP Web Proxy allows other people to bounce their web browser off of your computer to fake their real IP address to web servers.
