Yeah! Stand there and risk come confidential data being compromised! Monitor and Capture them stealing our customer info! Then try and get it back! Come on man. It's a pen-test, and there are NDA's in order. Don't take the chance. On 9/28/07, Joel R. Helgeson <joel () helgeson com> wrote:
I disagree, don't block access to the port. Monitor and capture it. Joel's First rule of forensics: Don't just do something, stand there! Watch it, monitor it. If it is a crafty backdoor, there are dozens of others to enable bad guys to regain entry. Blocking lets the hacker know you might be on to them. IF it is legit, then it could cause a problem. Telnet to the port, see what it says on connection; run fport or sysinternals utilities on the box to see the stack the program uses. -joel *From:* full-disclosure-bounces () lists grok org uk [mailto: full-disclosure-bounces () lists grok org uk] *On Behalf Of *Fabrizio *Sent:* Friday, September 28, 2007 1:31 PM *To:* Full-Disclosure *Subject:* Re: [Full-disclosure] .NET REMOTING on port 31337 If you think it's that critical, (i think it's that critical) start by blocking any connections from anywhere to that machine/port. See if anyone complains. Check any old firewall logs for that port while you're at it. Then continue your investigation!!

(not trying to be a smart ass) I'm gonna take a wild guess and say it's not a good thing...... Connect to it, and see if you get any output, if you haven't already done so.
