Snort rule update for March 11, 2021

Cisco Talos released the newest rule update for SNORTⓇ Thursday afternoon.

This latest release includes multiple rules to protect against the DEWMODE malware. Attackers exploit vulnerabilities in Accellion’s legacy File Transfer Appliance (FTA) to install this web shell. This malware family was first discovered in late February.

Here's a breakdown of the rule release:

Talos' rule release:

Talos has added and modified multiple rules in the file-other, malware-backdoor, netbios, os-windows and server-webapp rule sets to provide coverage for emerging threats from these technologies.
