<p class=MsoNormal>Hi all<o:p></o:p></p>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>I have been hacked but no idea how!!! I noticed somebody in
Eastern Europe came from an American IP and tried to call loads of
international numbers. Thankfully I had no credit with my VOIP out provider so
the calls went nowhere. But if I had credit it would all have been used up.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>I noticed hundreds of calls being made from <span
class=apple-style-span>clid and src being either UNKNOWN or as ASTERISK.</span><o:p></o:p></p>

</div>
<div>
<p class=MsoNormal>I've reported it to the authorities and they are doing a
backtrace to find the hacker, and in the meantime I have set my firewall that
ONLY SIP requests from my own IP address can connect so my home phones can
connect.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>My config is ALL NORMAL - I am careful about putting it up
here in case somebody else tries a fast one on me, but what I can tell you is
that my passwords are all SHA1 substrings and there is no way in hell somebody
could guess them. My box was not compromised either, as I went through my
message logs, my ISP also has a server firewall rule set up so that one false
password and the details are logged and I'm notified as somebody also tried a
dictionary attack on me.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>So now my system is all ruled up and I can only use it from
here, if I am out and about I can't use it.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>Anybody have any ideas about what I can do to try and find
this security hole??? I am sure it's a bug as surely nobody should have been
able to log into asterisk WITHOUT a password (from what i can see!!) and make
calls out leaving the source and id as UNKNOWN or ASTERISK.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>

<div>
<p class=MsoNormal>Thanks in advance<o:p></o:p></p>
