So you have finished writing your amazing DPA rule or hyper useful dashboard and are ready to win $5,000. What do you do next? Remember you can't win unless you follow the rules for entry!
The spirit of the entry is that we, the judges, need to know three things:
- What are you submitting?
- What does it do?
- How do we prove that your entry works as you describe?
Although we have nicely official rules and plan on sticking to them, try to help us answer those questions with your entry!What Do You Need?

There are a little more than 3 weeks left in the contest!
Are you working on your entry? Do you have questions about NetMon? Want to talk to an expert?
I'll be hosting an "Ask the Experts" session on Friday 8/11 from 10 - 11 am Mountain Standard Time. If you'd like to join me and some of the NetMon development team, we'd be happy to help you with DPA syntax, talk through entry ideas, or simply show off some of the things you can do with NetMon!
If you are still looking for ideas, how about writing rules and…

If you came to Black Hat 2017 or follow LogRhythm's Blog, you may have noticed two new posts showing how to use Network Monitor DPA rules for a deep dive into ICMP.
The first blog shows how to classify the type and code of ICMP traffic. Maybe you could start with this rule and make an interesting hunting or IT Operations dashboard. What would make ICMP traffic suspicious or interesting? Got a system that is over-pinging? How about all those timeouts?
The second blog is a great example of a novel threat detection entry. In the blog, we look at…

A few weeks ago, we showed how to use NetMon to look for EternalBlue and WannaCry in a LogRhythm Blog post. You may also want to see the latest on Petrya/NotPetrya, including some ways to detect signatuers with NetMon.
From a contest perspective, you may be most interested in an ongoing blog series showing how to look at individual bytes in a packet! The first part in the series describes the raw DPA code you need to extract bytes out of a packet. Other parts in the series will appear over the next few weeks showing how to…

We're happy to announce the release of NetMon 3.4.2. If you are working on an entry, or plan to work on an entry, we recommend you upgrade your NetMon to 3.4.2.
- The DPA editor has been improved. You'll have a much easier time writing and editing rules in 3.4.2
- We've fixed a bug with DNS. The DNS flags field is now a correct integer representation of the binary flags.
- If you haven't installed NetMon yet, and you plan to install it on a virtual platform, you'll have a much easier time getting it setup. We now recognize a…

Here at LogRhythm, we're full of ideas for what we want to do with Network Monitor. If you are enjoying working with Network Monitor and want some inspiration for the contest, consider tackling one of the following challenges:
Novel Threat Detection
We recently released some simple query rules to look for the EternalBlue exploit vector. What else is out there? We expect this category to require diving into the metadata that extract for each protocol and lifting out highly specific behaviors.
- Can you pick out Gh0st or Loki or BBSRat? They are all well-known protocols at this…
