Step-by-Step Configuration Procedure
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.
- Go to the Sekoia Intake page.
- Click on the
+ New Intakebutton at the top right of the page. - Search for your Intake by the product name in the search bar.
- Give it a Name and associate it with an Entity (and a Community if using multi-tenant mode).
- 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.
Instructions on the 3rd Party Solution
To configure F5 Distributed Cloud to send Security, Request, DNS or Audit logs, you need to follow these steps.
Configure a Global Log Receiver destination
- Log in to the F5XC Console
- Navigate to
Shared Configuration > Manage > Global Log Receiver. - Create a new Global Log Receiver with the following settings :
- Log Type:
Security Events - Log Message Selection: choose the Namespace(s) from where the logs will be sent
- Receiver Configuration: HTTP Receiver
- HTTP Uri: https://intake.sekoia.io/plain/batch
- Authentication:
BASIC- Username:
None - Password: YOUR_INTAKE_KEY
- Username:
- Log Type:
- Save your Global Log Receiver object.
Please find more information on how to configure remote loging here.
Specifically send only certain types of logs
You can create another Global Log Receiver object for each kind of log (Request, DNS and Audit)
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 F5 Distributed Cloud [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 F5 Distributed Cloud [BETA] on ATT&CK Navigator
Bazar Loader DGA (Domain Generation Algorithm)
Detects Bazar Loader domains based on the Bazar Loader DGA
- Effort: elementary
Covenant Default HTTP Beaconing
Detects potential Covenant communications through the user-agent and specific urls
- Effort: intermediate
Cryptomining
Detection of domain names potentially related to cryptomining activities.
- Effort: master
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: advanced
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
EvilProxy Phishing Domain
Detects subdomains potentially generated by the EvilProxy adversary-in-the-middle phishing platform. Inspect the other subdomains of the domain to identify the landing page, and determine if the user submitted credentials. This rule has a small percentage of false positives on legitimate domains.
- Effort: intermediate
Exfiltration Domain
Detects traffic toward a domain flagged as a possible exfiltration vector.
- Effort: master
Koadic MSHTML Command
Detects Koadic payload using MSHTML module
- Effort: intermediate
Nimbo-C2 User Agent
Nimbo-C2 Uses an unusual User-Agent format in its implants.
- Effort: intermediate
Potential Azure AD Phishing Page (Adversary-in-the-Middle)
Detects an HTTP request to an URL typical of the Azure AD authentication flow, but towards a domain that is not one the legitimate Microsoft domains used for Azure AD authentication.
- Effort: intermediate
Potential Bazar Loader User-Agents
Detects potential Bazar loader communications through the user-agent
- Effort: elementary
Potential Lemon Duck User-Agent
Detects LemonDuck user agent. The format used two sets of alphabetical characters separated by dashes, for example "User-Agent: Lemon-Duck-[A-Z]-[A-Z]".
- Effort: elementary
Potential LokiBot User-Agent
Detects potential LokiBot communications through the user-agent
- Effort: intermediate
Remote Access Tool Domain
Detects traffic toward a domain flagged as a Remote Administration Tool (RAT).
- Effort: master
Remote Monitoring and Management Software - AnyDesk
Detect artifacts related to the installation or execution of the Remote Monitoring and Management tool AnyDesk.
- Effort: master
SEKOIA.IO Intelligence Feed
Detect threats based on indicators of compromise (IOCs) collected by SEKOIA's Threat and Detection Research team.
- Effort: elementary
Sekoia.io EICAR Detection
Detects observables in Sekoia.io CTI tagged as EICAR, which are fake samples meant to test detection.
- Effort: master
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.
- Effort: master
WAF Correlation Block actions
Detection of multiple block actions (more than 30) triggered by the same source by WAF detection rules
- Effort: master
Event Categories
The following table lists the data source offered by this integration.
| Data Source | Description |
|---|---|
Web logs |
F5 Distributed Cloud WAF logs provide information about web application traffic and security events. |
Web application firewall logs |
F5 Distributed Cloud WAF logs provide information about security events and threats. |
API monitoring |
F5 Distributed Cloud API logs provide information about API traffic and security events. |
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.
