Snort rule update for Nov. 12, 2021

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

Tuesday morning's release includes a new rule to protect against the SQUIRRELWAFFLE attack we detailed in late October. SQUIRRELWAFFLE provides threat actors with an initial foothold onto systems and their network environments that can then be used to facilitate further compromise or additional malware infections depending on how adversaries choose to attempt to monetize their access. 

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