Sophos EDR

Overview

Sophos EDR monitors, detects and mitigates threats on endpoints. This EDR reduces the attack surface and prevent attacks from running with an anti-exploit, an anti-ransomware and advanced control technology.

This setup guide shows how to forward events produced by Sophos EDR to Sekoia.io.

  • Vendor: Sophos
  • Supported environment: Cloud
  • Detection based on: Telemetry
  • Supported application or feature: File monitoring, Process monitoring

Warning

If you have a "Partner" or "Organization" entity, you need to do the following procedure on every tenant attached to it. Please find more information on the official documentation

In the Sophos Central Admin console:

  1. On the left panel, go to Global Settings and select API Credentials Management.
  2. Click on Add Credential to create a credential dedicated to Sekoia.io.
  3. Give it a name, select the role Service Principal ReadOnly and click on Add.
  4. In the API credential Summary, copy the Client ID and the Client Secret. It will be used later in Sekoia.io to retrieve the events.

Create the intake

  1. Go to the Intake page and create a new Sophos EDR intake.
  2. Copy the associated Intake key

Pull events

  1. Go to the Playbook page.
  2. Click on + PLAYBOOK and choose Create a playbook from scratch.
  3. Give it a name and a description and click on Next.
  4. In Choose a trigger, select the Get Sophos events.
  5. Click on the Get Sophos events module on the right sidebar and in the Module Configuration section, select Create new configuration.

  6. Write a name and paste the client_id and client_secret from the Sophos console and click on Save.

    Info

    • If you want to change the region with your own region, you can find your region via protect devices field, first click on Protect Devices, Then copy link of any download links and finally Check the region that appears as part of the URL.
    • No need to change the Oauth2 Authorization Url for the moment, as this's the only endpoint to get a JWT token

  7. In the Trigger Configuration section, click on Create new configuration.

  8. Write a name, choose a frequency - Default is 60 -, paste the intake_key associated to your Sophos EDR intake and click on Save.
  9. On the top right corner, start the Playbook. You should see monitoring messages in the Logs section.
  10. Check on the Events page that the Sophos logs are being received.

Raw Events Samples

In this section, you will find examples of raw logs as generated natively by the source. These examples are provided to help integrators understand the data format before ingestion into Sekoia.io. It is crucial for setting up the correct parsing stages and ensuring that all relevant information is captured.

Detection section

The following section provides information for those who wish to learn more about the detection capabilities enabled by collecting this intake. It includes details about the built-in rule catalog, event categories, and ECS fields extracted from raw events. This is essential for users aiming to create custom detection rules, perform hunting activities, or pivot in the events page.

The following Sekoia.io built-in rules match the intake Sophos EDR. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.

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. The vulnerability is due to Microsoft Exchange Server not randomizing the keys on a per-installation basis resulting in them using the same validationKey and decryptionKey values. With knowledge of these, values an attacker can craft a special viewstate to use an OS command to be executed by NT_AUTHORITY\SYSTEM using .NET deserialization. To exploit this vulnerability, an attacker needs to leverage the credentials of an account it had already compromised to authenticate to OWA.

Discord Suspicious Download

Discord is a messaging application. It allows users to create their own communities to share messages and attachments. Those attachments have little to no overview and can be downloaded by almost anyone, which has been abused by attackers to host malicious payloads.

  • Effort: intermediate
Domain Trust Created Or Removed

A trust was created or removed to a domain. An attacker could perform that in order to do lateral movement easily between domains or shutdown the ability of two domains to communicate.

Possible Replay Attack

This event can be a sign of Kerberos replay attack or, among other things, network device configuration or routing problems.

  • Effort: intermediate
Process Trace Alteration

PTrace syscall provides a means by which one process ("tracer") may observe and control the execution of another process ("tracee") and examine and change the tracee's memory and registers. Attacker might want to abuse ptrace functionnality to analyse memory process. It requires to be admin or set ptrace_scope to 0 to allow all user to trace any process.

Suspicious Download Links From Legitimate Services

Detects users clicking on Google docs links to download suspicious files. This technique was used a lot by Bazar Loader in the past.

  • Effort: intermediate
Suspicious PROCEXP152.sys File Created In Tmp

Detects the creation of the PROCEXP152.sys file in the application-data local temporary folder. This driver is used by Sysinternals Process Explorer but also by KDU (https://github.com/hfiref0x/KDU) or Ghost-In-The-Logs (https://github.com/bats3c/Ghost-In-The-Logs), which uses KDU. Note - Clever attackers may easily bypass this detection by just renaming the driver filename. Therefore just Medium-level and don't rely on it.

  • Effort: advanced
Suspicious TOR Gateway

Detects suspicious TOR gateways. Gateways are often used by the victim to pay and decrypt the encrypted files without installing TOR. 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.

Transformed Events Samples after Ingestion

This section demonstrates how the raw logs will be transformed by our parsers. It shows the extracted fields that will be available for use in the built-in detection rules and hunting activities in the events page. Understanding these transformations is essential for analysts to create effective detection mechanisms with custom detection rules and to leverage the full potential of the collected data.
