Snort rule update for Feb. 16, 2021

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

Today's update includes several rules to protect against the ObliqueRAT malware from making an outbound connection to its command and control server. Cisco Talos has documented this trojan several times. If installed, ObliqueRAT can give its operators the ability to execute arbitrary commands, exfiltrate files, drop additional payloads and terminate processes on the infected endpoint. 

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

Shared object rules	Modified shared object rules	New rules	Modified rules
