Cisco Talos released two new rule sets for SNORTⓇ this week, which you can view here and here.
There are multiple rules to protect against the exploitation of the highly publicized Spring4Shell vulnerabilities that could lead to remote code execution. Spring is a popular framework used to develop Java applications. Snort SIDs 30790 - 30793, 59388 and 59416 can detect this activity.
For more on these vulnerabilities, read the Talos blog here.
All users 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, which you can upgrade to here.
Snort's rule blog posts are switching to a weekly recap format, rather than releasing every day a new rule update is released. If you have any feedback on this blog format, please reach out to us on Twitter @Snort.
