CVE-2020-0688 Microsoft Exchange Server Exploit

Detects the exploitation of CVE-2020-0688. The POC exploit a .NET serialization vulnerability in the Exchange Control Panel (ECP) web page.

TOR Usage Generic Rule

Detects TOR usage globally, whether the IP is a destination or source. TOR is short for The Onion Router, and it gets its name from how it works. TOR intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult. Before a network packet starts its journey, user’s computer chooses a random list of relays and repeatedly encrypts the data in multiple layers, like an onion. Each relay knows only enough to strip off the outermost layer of encryption, before passing what’s left on to the next relay in the list.

Configure

In this guide, you will configure your Symantec Endpoint Protection Manager or your Symantec Endpoint Security to forward events through syslog.

Prerequisites

An internal syslog concentrator is required to collect and forward events to Sekoia.io.

Enable Syslog forwarding

Log on the console of our management server and follow this guide to enable logs forwarding and provide the IP, the transport protocol (we are recommending TCP) and the listening port (514) of the concentrator.

Create the intake

Go to the intake page and create a new intake from the format Symantec Endpoint Protection.

Forward logs to Sekoia.io

Please consult the Syslog Forwarding documentation to forward these logs to Sekoia.io.
