botnet detector?

Hi All,

During the recent DDOS attacks, I have been getting
a lot of complaints from customers about eMail and browsers
not making connection. I thought it was just the bottleneck
caused by the DDOS network flood.

Now I am wondering, maybe they were part of the botnet.
Other than keeping their antivirus up to date, does
anyone have a favorite way of checking to see if someone
is part of a botnet?

I presume network traffic from the botnet will only occur
when triggered and the rest of the time be dormant.
So watching network traffic would only work during the
attack. Am I right?

Many thanks,
-T

This is a WinXP news group. Such a question is better served in a malware

What do you mean "recent DDoS attacks" ? There are DDoS attacks taking
place everyday against a myriad of hosts some you may know or heard of and
some you most likely haven't heard of and others that have gone unreported.
It's like sayiong "during the recent rain storm" and fail to provide a
locality. Your stating "During the recent DDOS attacks..." has no context.

As for whether you network is unwilling component of a Botnet. You have to
sniff the network and examine the traffic. Check you logs, routers and
border gateways. Install BotHunter on your network -

In short, Botnets generate detectable network traffic.

I have a long history with the guys on this group and I
do appreciate what they bring to the table. But, I will look
over there too. Thank you for the tip.

I was talking about the ones you hear on the news. The SpamHaus
attack in particular.

place everyday against a myriad of hosts some you may know or heard of
and some you most likely haven't heard of and others that have gone
unreported. It's like sayiong "during the recent rain storm" and fail to

The user's manual would show up in Firefox 20, 64 bit for Linux. It
also give no clue as to which plugin it is looking for either.

What I am puzzled by is how this thing is used. Does it require
a two port firewall such as iptables? (I am good at iptables).
Or does it just sniff passing traffic? If it is just sniffing,
how does it get around targeted traffic from a switching hub?

I noticed they have a live CD in their future. Very cool.

In short, Botnets generate detectable network traffic.

All the time? Or only when triggered?

Thank you for the help!

How about Sysinternals "TCP View"? But would that only show when
the botnet was triggered?

No. I wrote sniff the network.

You are not going to catch nodes beaconing to a C2 server that way.

That may be be that's not how News Groups are used. The Botnet is a network, the infected
computers can be ANY OS on the network from Windows Servers to Linux. Therefore your
WinXP centricity is hurting your ability to get the propert information.

You don't ask a Harley Davidson group how to fix a Yamaha.
