Snort rule update for Nov. 4, 2021

The newest SNORTⓇ rule update from Cisco Talos is now available.

We apologize that these rule blog posts have not been as frequent recently — our comms team was on a bit of a fall break. But, we're excited to let everyone know about today's rule release. 

We have multiple rules available to protect against the exploitation of multiple vulnerabilities Cisco disclosed in some of their routers that could allow unauthenticated attackers to log in using hard-coded credentials or default SSH keys.

Here's a full breakdown of the rest of Tuesday's rule update:

There were no changes made to the snort.conf in this release.

Cisco Talos' rule release: 

Talos has added and modified multiple rules in the browser-chrome, malware-cnc, malware-other and server-webapp rule sets to provide coverage for emerging threats from these technologies.

You can subscribe to Talos' newest rule detection functionality for as low as $29 a year with a personal account. Be sure and see our business pricing as well here. The Snort 3 release is also here after years of development and improvements. Upgrade here.
