Snort rule update for Nov. 30, 2021

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

Tuesday morning's release includes a new rule to protect against the high-profile DarkSide ransomware. The group, also known as DarkMatter, targeted several high-profile companies across the globe this year, including two companies in the U.S. food and agriculture sector.
