Snort rule update for June 1, 2021

Cisco Talos released the newest SNORTⓇ rule update Tuesday afternoon.

This release includes several new rules to protect against attacks from Russian Foreign Intelligence Service (SVR) cyber actors (aka APT29 and CozyBear). A joint release from U.S. intelligence organizations outlined the vulnerabilities this group uses to target many of its victims.

Here's a breakdown of everything in today's release:
