Hey, I'm going thru logs, and I see some very common and interesting things<br>
that the hackers are looking for.<br>
<br>
In a whole bunch of scans, I've noticed that the first guess or two for sip
accounts<br>
is usually a 10-digit number. I'm asking myself, why these numbers? Are they
looking<br>
for a voip trunk? Or is it just like a serial number for the scan? What?<br>
<br>
Here's some examples:<br>
<br>
2648061411<br>
3190339404<br>
2685608247<br>
3358171034<br>
2092652562<br>
2206598858<br>
<br>
Just trying to follow the advice: "Know thy Enemy"<br>
