2.9.11.0 beta has been released!

Join us as we welcome Snort 2.9.11.0 to the family, in beta form!


Right off the bat, you will notice that we are going from 2.9.9.0 to 2.9.11.0, skipping over 2.9.10.0. Just to clarify, 2.9.10.0 was an internal only release. We decided not to ship it to the public because timing of back to back 2.9.10 and 2.9.11 releases, and thought it would be better for the community to just release one instead of two. All 2.9.10 features and fixes are in 2.9.11, so you're not missing anything, just making it easier on the community.


We will be modifying the EOL slightly, as we are going to be keeping versions around a little longer. We aren't quite sure what this will look like yet, but rest assured we will be updating the blog when we do.


Here's some release notes:


  • New additions
    • Changes to eliminate Snort restart when there are changes to the memory allocated for preprocessors, by releasing unused or least recently used memory when needed.



  • Improvements
    • Enhanced RTSP metadata parsing to match the user-agent field to detect RTSP traffic over Windows Media.
    • Performance improvement when SYN rate limit has reached and drop is configured as next action
    • Control-socket and side-channel support for FreeBSD platform.
    • Fixed an issue where IoQ driver was getting into bad state due to non-graceful exit.
    • Fixed issue in file signature lookup for retransmitted FTP packet.
    • Enhanced the processing of SIP/RTP future flows without ignoring them.
    • Changes made in PDF/SWF decompression by adding boundary to the size of the decompressed data.
    • Added a null check to prevent copy unless debugHostIp is configured in AppId.
    • Fixed issue where FTP file type block doesn't work for retried download.
    • Resolved issue where Snort is inappropriately handling traffic for which AppId was creating future flow.
    • Performance improvements for SIP/RTP audio and video data flow in AppId.
    • Performance and stability improvements in FTP preprocessor like incorrect referencing of ftp_data_session after its pruned.
    • Stability improvement by resolving valgrind reported issues in AppId.
    • Improved flushing mechanism for HTTP POST header.

Snort 3 Community Rules have been posted!

As our development and deployment of Snort 3 (Codenamed: Snort++) continues, we've posted the first community ruleset on Snort.org.  We announced this last week at BlackHat at the Cisco booth by Patrick Mullen.  These rules have the same AUTHORS and LICENSE file as the 2.x version of the community ruleset, except all the rules contained have been converted to the Snort 3 rule language.

So for example the rule:

alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"MALWARE-CNC Win.Trojan.Ismdoor variant outbound connection"; flow:to_server,established; content:"commandId="; fast_pattern:only; http_uri; content:"/Home/"; depth:6; http_uri; metadata:impact_flag red, policy balanced-ips drop, policy security-ips drop, ruleset community, service http; reference:url,blog.vectranetworks.com/blog/an-analysis-of-the-shamoon-2-malware-attack; classtype:trojan-activity; sid:42129; rev:1;)

In Snort 3, will now look like this:

 alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS ( msg:"MALWARE-CNC Win.Trojan.Ismdoor variant outbound connection"; flow:to_server,established; http_uri; content:"commandId=",fast_pattern,nocase; content:"/Home/",depth 6; metadata:impact_flag red,policy balanced-ips drop,policy security-ips drop,ruleset community; service:http; reference:url,blog.vectranetworks.com/blog/an-analysis-of-the-shamoon-2-malware-attack; classtype:trojan-activity; sid:42129; rev:1; )

You can notice the difference in syntax, in the italicized sections above.

You can download the ruleset on our downloads page on Snort.org.

This can't be automated yet with pulledpork, as pulledpork doesn't understand the Snort 3 format yet, but as time marches on, this evolutionary problem will correct itself.

We look forward to the thousands and thousands of users on Snort 3 to download and try this ruleset out from Talos.

New Snort Mailing Lists are alive!

This evening, if you are a member of the Snort Mailing lists (-users, -sigs, -devel, and/or -openappid) you should have received a welcome message to the new version of the respective list, at its new home on the new server.

You can see the list of Snort lists and of course join (if you are not already a member) here:

https://lists.snort.org/mailman/listinfo

All settings to the lists should be the same, and all users have been (or are being as I type this) migrated from the old lists on Sourceforge, to the new lists.

Effective immediately, I have set the moderation flag on the Sourceforge mailing lists, and all further email to those lists will be rejected with a message to post to the new list.  After an indeterminate period of time, I will decommission the old lists.

I am working with Sourceforge to get a dump of our archives, so we may retain that history on our servers, in the meantime you can find the archives for the mailing lists on Marc.  All emails on the new list will also be archived on Marc.

Hopefully everything went well, and I haven't inconvenienced too many people.  I sincerely apologize if I did.  I had been planning to move off of Sourceforge for years, and hadn't simply because of the history we had built there.  However, with their recent changes in policy, moving the lists at this time made sense.

Any feedback about the move, please contact me at: snort-users@lists.snort.org.

We look forward to seeing everyone on our new server, which is not only on an updated version of the mailman software, but also now without Sourceforge's ads at the bottom of every post!

Thanks for your patience and understanding.

Sourceforge Hosted Snort Mailing Lists

All—

Some recent changes from Sourceforge (where the Snort mailing lists have been hosted since the start of the project, nearly 20 years ago) to their Mailman infrastructure has left us unable to access the member list. Which means we can no longer unsubscribe, subscribe, ban, moderate, clear, or otherwise have any control over the subscribers of the mailing list. Something that as a community manager, prevents me from managing… the community…

The changes outlined here: https://sourceforge.net/blog/sourceforge-project-e-mail-policy-update/ put quite a hinderance on the ability to manage the lists, and therefore, we are looking into options of moving off of Sourceforge.

More news will come soon.

Snort 2.9.7.6 is *now* EOL!

Even though we announced the EOL of 2.9.7.6 back in March,  we kept 2.9.7.6 around for while to help the people that could not move off of 2.9.7.6 immediately.

However, our download count for 2.9.7.6 is down to "hey, I forgot about this install" levels, so we've removed the build from our package distribution.

In the near future we will have an announcement about adjusting our EOL schedule to better serve the community.  Keep your eyes on this blog!

We created an infographic to illustrate our coverage for the WannaCry Ransomware for another group, and we thought that the Snort community would love to have this as well

Snort++ Vulnerabilities Found

Thanks go to Bhargava Shastry, who reported several issues to the Snort Team on Github for which two CVEs will be created.  Links to the issues on github are given at the end.  Fixes are on github now, tagged BUILD_233.  The bugs afflict all prior versions so please pull the latest.  Here is a description of the problems:

Ether Type Validation (CVE-2017-6657)

Since valid ether type and IP protocol numbers do not overlap, Snort++ stores all protocol decoders in a singe array.  That makes it possible to craft packets that have IP protocol numbers in the ether type field which will confuse the Snort++ decoder.   For example, an eth:llc:snap:icmp6 packet will cause a crash because there is no ip6 header with which to calculate the icmp6 checksum.  Affected decoders include gre, llc, trans_bridge, ciscometadata, linux_sll, and token_ring.  The fix adds a check in the packet manager to validate the ether type before indexing the decoder array.  An out of range ether type will will raise 116:473.

Buffer Overread (CVE-2017-6658)

Another problem with the decoder array was also discovered.  The size was off by one making it possible read past the end of array with an ether type of 0xFFFF.  Increasing the array size solves this problem.

The links to the github issues are given below.  Thanks again to Bhargava for reporting the issues.

Snorter -- an automatic Snort, Barnyard2, and PulledPork installation script.

Snorter

We all know that sometimes, the installation of the latest version of Snort, Barnyard2 and PulledPork could be pretty tedious, specially if you have to install lots of Snorts in different machines.

Cloning Hard Disks is the easy way to do it if all the machines in which we are going to install this IDS are the same but, what happens if you are using different machines, and you want to install Snort in all of them? It doesn’t matter if you install a Snort for PCAP analysis or for using it as IDPS: It’s hard work!

I made a guide some time ago where I explain, step by step, how to install and configure a Snort in a Debian based machine, but it was always the same: too long for the short time I have, chiefly if I wanted to do a fast PCAP analysis to discard malware infections or other network traces, for example. This is why I decided to convert my PDF guide into a bash script, which installs all dependencies and also creates a MySQL database for the alerts.

This is how Snorter was born.

The only thing you need is an Oinkcode, available for free in snort.org webpage, needed for automatically update the Snort rules, and the Network Interface which is going to be used (eth0, wlan0, etc…)

For installing, you only need to clone the repository:
git clone https://github.com/joanbono/Snorter
cd Snorter/src
bash Snorter.sh -o  -i

The script is mostly independent, the only interaction needed for the installation is the specification for the $HOME_NET and the $EXTERNAL_NET, but do not worry, is fully documented in the Manual.
Also, I have added a Dockerfile for testing, with the possibility to use websnort, a web interface which allows the analyst to upload a PCAP file and then see graphically the alerts, and adds to the Snorter an API option for submitting pcaps using curl.

I started this tool with the purpose of making my life easier, but the program has evolved, and now it’s time to share it.

The next step is to port it to Red Hat/CentOS, any help is welcome!

Feel free to open issues, improve the script and add more options, but, above all, enjoy the free time you will have from now.

Snort Video Series

Want to get better acquainted with Snort and see an overview of Snort IPS? Want to see how you can install and configure Snort IPS on your machine? Look no further. In conjunction with Cisco Engineering Learning & Development, we created a video to give an overview of Snort installation, configuration, and deployment on a computer. The video is a great place for you to begin to understand Snort and see installation from start to finish. You can find the MP4 on our Documents page under Additional Resources section of our website titled Snort installation and configuration TechByte.


This is the first video in the TechByte series being created by Cisco Engineering Learning & Development and Snort. The next videos in this series coming later this year will be on How to Write a Snort Rule and Advanced Snort Rule Writing. Stay tuned.
