Last week I posted a diary about analyzing outgoing network traffic and asked our readers to comment what data sources they use when monitoring outbound connections our users establish.

Besides the sources I listed in the original diary we got quite a few comments and some good questions, so I’m combining all these in this, second, diary:

These include the lists I verified in the mean time – for more check comments in the first diary.

One of our readers, Arnim, also asked about a potentially very useful list of IP addresses belonging to remote access services such as LogMeIn, NetViewer and similar. I’m not aware of such a list but it would be very useful. Emerging Threat’s has something similar – a list of outgoing ToR nodes but that only helps you figure out if someone that visited your network used ToR. The list is available at http://rules.emergingthreats.net/open/suricata/rules/tor.rules

Thanks to everyone that submitted their comments, including Christian, Ben, Arnim, Hal, Matt, Brent and many others.

Hi,

I hope this will be helpful http://callbackdomains.wordpress.com/
Here daily i will be posting only Malware Callback Domains and IPs.
They are extracted from behaviour analysis of malware samples and filtered based on heuristics removing the legitimate domains/IPs.

Any hit to those IPs or domains is a confirmed malware infection.
You can validate them by googling the domain/IP on internet.
@Uma: That looks like a useful resource for automatic firewall/IDP maintenance. Are the lists available in a more-easily-usable downloadable file format so that we don't have to write a blog scraper to get updates?
You can get the list from malwaredomainlist via this link:

@John

You can find an overview of the downloadable lists at malwaredomainlist.com here:
