2. Click General > Syslog
3. Check Enable syslog sending
4. Select JSON as the format of the payload
5. Select Syslog as the format of the envelope
6. Select Information as the minimal log level
7. Check all event types

Instruction on Sekoia

Configure Your Intake

This section will guide you through creating the intake object in Sekoia, which provides a unique identifier called the "Intake key." The Intake key is essential for later configuration, as it references the Community, Entity, and Parser (Intake Format) used when receiving raw events on Sekoia.

1. Go to the Sekoia Intake page.
2. Click on the + New Intake button at the top right of the page.
3. Search for your Intake by the product name in the search bar.
4. Give it a Name and associate it with an Entity (and a Community if using multi-tenant mode).
5. Click on Create.

Note

For more details on how to use the Intake page and to find the Intake key you just created, refer to this documentation.

Configure a forwarder

To forward events using syslog to Sekoia.io, you need to update the syslog header with the intake key you previously created. Here is an example of your message before the forwarder

<%pri%>1 %timestamp:::date-rfc3339% %hostname% %app-name% %procid% LOG RAW_MESSAGE

and after

<%pri%>1 %timestamp:::date-rfc3339% %hostname% %app-name% %procid% LOG [SEKOIA@53288 intake_key=\"YOUR_INTAKE_KEY\"] RAW_MESSAGE

To achieve this you can:

• Use the Sekoia.io forwarder which is the official supported way to collect data using the syslog protocol in Sekoia.io. In charge of centralizing data coming from many equipments/sources and forwarding them to Sekoia.io with the apporpriated format, it is a prepackaged option. You only have to provide your intake key as parameter.
• Use your own Syslog service instance. Maybe you already have an intance of one of these components on your side and want to reuse it in order to centralize data before forwarding them to Sekoia.io. When using this mode, you have to configure and maintain your component in order to respect the expected Sekoia.io format.

Warning

Only the Sekoia.io forwarder is officially supported. Other options are documented for reference purposes but do not have official support.

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.

Related Built-in Rules

The following Sekoia.io built-in rules match the intake ESET Protect [BETA]. 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.

SEKOIA.IO x ESET Protect [BETA] on ATT&CK Navigator

Active Directory Data Export Using Csvde

Detects the use of Csvde, a command-line tool from Windows Server that can be used to export Active Directory data to CSV files. This export doesn't include password hashes, but can be used as a discovery tool to enumerate users, machines and group memberships.

• Effort: elementary

AdFind Usage

Detects the usage of the AdFind tool. AdFind.exe is a free tool that extracts information from Active Directory. Wizard Spider (Bazar, TrickBot, Ryuk), FIN6 and MAZE operators have used AdFind.exe to collect information about Active Directory organizational units and trust objects

• Effort: elementary

Adexplorer Usage

Detects the usage of Adexplorer, a legitimate tool from the Sysinternals suite that could be abused by attackers as it can saves snapshots of the Active Directory Database.

• Effort: advanced

Advanced IP Scanner

Detects the use of Advanced IP Scanner. Seems to be a popular tool for ransomware groups.

• Effort: master

AutoIt3 Execution From Suspicious Folder

Detects AutoIt3 execution from an unusual/suspicious folder. Legitimate folders are "Program Files" and "AppData\Local". AutoIt3.exe is a legitimate process used to execute AutoIt program files, which are used by legitimate software, custom scripts, but also malware. Finding AutoIt3 execution from unusual/suspicious folder can help detect malware activities, such as DarkGate execution. The detection rule can be tailored to your environment and your use of AutoIt3 by filtering out folder's execution of legitimate applications or scripts.

• Effort: advanced

Bloodhound and Sharphound Tools Usage

Detects default process names and default command line parameters used by Bloodhound and Sharphound tools.

• Effort: intermediate

Certificate Authority Modification

Installation of new certificate(s) in the Certificate Authority can be used to trick user when spoofing website or to add trusted destinations.

• Effort: master

Certify Or Certipy

Detects the use of certify and certipy which are two different tools used to enumerate and abuse Active Directory Certificate Services.

• Effort: advanced

Cobalt Strike Default Beacons Names

Detects the default names of Cobalt Strike beacons / payloads.

• Effort: intermediate

Cryptomining

Detection of domain names potentially related to cryptomining activities.

• Effort: master

Csrss Child Found

The csrss.exe process (csrss stands for Client / Server Runtime Subsystem) is a generic Windows process used to manage windows and Windows graphics. This process should not create a child process or it is very rare.

• Effort: intermediate

DNS Query For Iplookup

Detects dns query of observables tagged as iplookup.

• Effort: master

Discovery Commands Correlation

Detects some frequent discovery commands used by some ransomware operators.

• Effort: intermediate

Dllhost Wrong Parent

Dllhost.exe is a process belonging to Microsoft Windows Operating System. The dllhost.exe file manages DLL based applications. This rule analyse if the parent of this process is a legitimate one or not.

• Effort: master

Dynamic DNS Contacted

Detect communication with dynamic dns domain. This kind of domain is often used by attackers. This rule can trigger false positive in non-controlled environment because dynamic dns is not always malicious.

• Effort: master

ESET Protect Intrusion Detection

Detects when the solution ESET Protect detects an intrusion.

• Effort: master

ESET Protect Malware

Detects when Eset Protect tagged an event as linked to a malware with infected files.

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.
