Other than using the cmd prompt to see connections, you can use a handy program called TCPView.
It does the same thing as the cmd prompt, but it also shows what process it belongs to in the same window.
Heres a link, TCPView for Windows
Hope this helps you a bit more.
Nice lil tutorial kinda old school basic way to check
Couldn't you just use a packet sniffer, it would be much easier..
Wireshark: Go deep.
Much easier - it shows in and out and what protocol.
You could even use PeerGuardian - just check the box show allowed connections. Honestly, using Wireshark would be quicker than having to go through the command prompt.
Completely true.
Seriously everyone, this DOS command does nothing against any modern day malware. Good malware replaces the netstat program with a modified one that won't list the malware sockets, or disguises itself as a system process.
I mean, seriously, who the f*ck would name their malware "VIRUS.exe".... they would call it something like "win32sys.exe" or something that nobody would delete, unless they knew the Windows system files by heart.
Windows has many C-Win32/ASM-MASM libraries you can use to make your process invisible/seem like a system process/etc. As I said, nearly all malware today have to perform these tricks to get anywhere.
Anyone skilled could make it a service, not a foreground application as well, making it more tricky, and making it look even more like a system process.
Also, killing it's connections would do little. They nearly all will have another process running that detects when it's connections are killed, and it just reconnects. And, most malware use the registry to autostart, meaning it will return on the next boot, unless completly removed.
Trying to trick an external firewall administered by knowledgeable people however, is very different.
