    Exclamation something trying to phone home on port 2491 ?

    ok guys and gals..
    I believe this is the first time that I ever asked for some help and I'm hoping
    that someone can shed a little light on what this may be.

    First off.. this is not for me.. but came from an online friend that asked if I'd help.

    here we go from him..
    do you know wtf is?

    Been gettin alot of crap spam mails as always to one of my hotmails, and 4-5 a day try and connect to this site going throu port service port 2491.

    FW blocks it everytime, but its a pain in the bum not even knowing what it is.

    Ideas? and see the "guess who" message (safe to check i think)
    my reply:

    are you sure this isn't some "friend" who's yanking your chain ?
    and gave this info:
    arin says this:

    uh.. this may be totally off the wall but do you know a David J Bush ?

    hehehe nah.. probably not.. wouldn't be that easy..

    google doesn't show any results for . it has 500 hits for twixter.. and arin doesn't have any record of twixter.. or
    but if it's trying to call home.. my best guess is that you have a trojan/backdoor on your box.

    acording to this port list at

    it gives :

    2491 tcp conclave-cpp Conclave CPP
    2491 udp conclave-cpp Conclave CPP

    but searching google for Conclave or Conclave CPP didn't turn up anything very enlightening
    later on i suggested that if nothing comes to light that he'd have to conact the admin at bellsouth.. but i have doubts that he'll want to do that unless all the other avenues come to a dead end.. I asked him about what trojan scanners he's using ( i know he stays up on his AV dats) but he hasn't responded yet..
    I'm hoping that by the time he does check in.. that I'll be able to offer him more info.
    (courtesy of you folks)

    any thoughts ? suggestions ?

    TIA.. sdg..

    Try this program, it helped me during a similar attack I investigated. You can download a free 15 day trial. I hope this helps. Let me know...
    I have a question; are you the bug, or the windshield?

    Hmm sounds like a trojan/bot or it could be spyware but all that is on the site is
    Guess Who?
    so im guessing that it could be some trojan maybe a worm here is my whois query on the domain

    Domain Name: TWIXTER.NET

    sdg did you tell him to scan for trojans virii spyware etc maybe sending Brad Smith an email might resolve why he has something wanting to connect to after all he is the registrant of the domain good luck with whatever it is

    edit:the port that is wanting to connect to is reserved for Conclave CPP
