Snort rule update for June 29, 2021

Cisco Talos released the newest SNORTⓇ ruleset this morning.

Tuesday's rule update includes new rules to protect against the "Victory" backdoor recently being used by a state-sponsored APT as part of a surveillance operation. There are also new rules associated with the same attack that block an RTF file the attackers use with the RoyalRoad weaponizer.

Talos also released coverage for a recently disclosed vulnerability in Cisco's Adaptive Security Appliance that is being exploited in the wild.

Here's a full breakdown of today's release:
