Snort rule update for Feb. 23, 2021

Cisco Talos released the newest rule update for SNORTⓇ on Tuesday morning.

Today's release includes multiple rules to defend against attacks from the Gamaredon threat group. Talos researchers have spotted this group carrying out multiple attacks recently that appear to be mainly motivated by stealing users' information and selling it to other threat actors. For more on this group, check out Talos' full research post.
