Snort rule update for April 20, 2021

Cisco Talos released the latest SNORT® rule update Tuesday afternoon.

Today's release includes several rules to protect against the exploitation of a recently discovered vulnerability in the VMware View Planner virtual desktop deployment platform. An attacker could use this vulnerability to gain the ability to execute remote code on the victim machine.

There is also one rule preventing the Remcos RAT from making an outbound connection to its command and control server. Remcos is recently known for being attached to COVID-19-themed spam campaigns

Here's a breakdown of Tuesday's rule release:
