Deploying the Data Collection Architecture
This section will guide you through creating all the AWS resources needed to collect AWS logs. If you already have existing resources that you want to use, you may do so, but any potential issues or incompatibilities with this tutorial will be your responsibility.
Prerequisites
In order to set up the AWS architecture, you need an administator access to the Amazon console with the permissions to create and manage S3 buckets, SQS queues, S3 notifications and users.
To get started, click on the button below and fill the form on AWS to set up the required environment for Sekoia 
You need to fill 4 inputs:
- Stack name - Name of the stack in CloudFormation (Name of the template)
- BucketName - Name of the S3 Bucket
- IAMUserName - Name of the dedicated user to access the S3 and SQS queue
- SQSName - Name of the SQS queue
Read the different pages and click on Next, then click on Submit.
You can follow the creation in the Events tab (it can take few minutes).
Once finished, it should be displayed on the left CREATE_COMPLETE. Click on the Outputs tab in order to retrieve the information needed for Sekoia playbook.
Create a S3 Bucket
Please refer to this guide to create a S3 Bucket.
Create a SQS queue
The collect will rely on S3 Event Notifications (SQS) to get new S3 objects.
- Create a queue in the SQS service by following this guide
- In the Access Policy step, choose the advanced configuration and adapt this configuration sample with your own SQS Amazon Resource Name (ARN) (the main change is the Service directive allowing S3 bucket access):
{ "Version": "2008-10-17", "Id": "__default_policy_ID", "Statement": [ { "Sid": "__owner_statement", "Effect": "Allow", "Principal": { "Service": "s3.amazonaws.com" }, "Action": "SQS:SendMessage", "Resource": "arn:aws:sqs:XXX:XXX" } ] }
Important
Keep in mind that you have to create the SQS queue in the same region as the S3 bucket you want to watch.
** Create a S3 Event Notification **
Use the following guide to create S3 Event Notification. Once created:
- Select the notification for object creation in the Event type section
- As the destination, choose the SQS service
- Select the queue you created in the previous section
Forward findings to S3
To export forward findings to S3, please refer this guide.
You have to:
- In your AWS console, navigate to:
Services > GuardDuty > Settings - Go to the
Finding export optionssection - Select the bucket you created previously. Ensure your bucket policy allows GuardDuty to add new objects
- Select or create a key for the KMS encryption
- Click the button
Save
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.
Pull events
Create your intake
- Go to the intake page and create a new intake from the
AWS GuardDuty. - Set up the intake account configuration with the AWS Access Key, the secret key and the region name. Set up the intake configuration with the name of the SQS queue
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 AWS GuardDuty. 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 AWS GuardDuty on ATT&CK Navigator
AWS GuardDuty High Severity Alert
GuardDuty has detected a threat with a high severity level. A High severity level indicates that the resource in question (an EC2 instance or a set of IAM user sign-in credentials) is compromised and is actively being used for unauthorized purposes.
- Effort: master
AWS GuardDuty Low Severity Alert
GuardDuty has detected a threat with a low severity level. A low severity level indicates attempted suspicious activity that did not compromise your network, for example, a port scan or a failed intrusion attempt.
- Effort: master
AWS GuardDuty Medium Severity Alert
GuardDuty has detected a threat with a medium severity level. A Medium severity level indicates suspicious activity that deviates from normally observed behavior and, depending on your use case, may be indicative of a resource compromise.
- Effort: master
Burp Suite Tool Detected
Burp Suite is a cybersecurity tool. When used as a proxy service, its purpose is to intercept packets and modify them to send them to the server. Burp Collaborator is a network service that Burp Suite uses to help discover many kinds of vulnerabilities (vulnerabilities scanner).
- Effort: intermediate
Correlation Potential DNS Tunnel
Detects domain name which is longer than 95 characters. Long domain names are distinctive of DNS tunnels.
- Effort: advanced
Cryptomining
Detection of domain names potentially related to cryptomining activities.
- 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
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
Internet Scanner
Detects known scanner IP addresses. Alert is only raised when the scan hits an opened port, on TCP or UDP. This could be a very noisy rule, so be careful to check your detection perimeter before activation.
- Effort: master
Internet Scanner Target
Detects known scanner IP addresses. Alert is only raised when the scan hits an opened port, on TCP or UDP and group by target address. This could be a very noisy rule, so be careful to check your detection perimeter before activation.
- Effort: master
Nimbo-C2 User Agent
Nimbo-C2 Uses an unusual User-Agent format in its implants.
- Effort: intermediate
Potential Bazar Loader User-Agents
Detects potential Bazar loader communications through the user-agent
- Effort: elementary
Potential DNS Tunnel
Detects domain name which is longer than 95 characters. Long domain names are distinctive of DNS tunnels.
- Effort: advanced
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
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
Remote Monitoring and Management Software - Atera
Detect artifacts related to the installation or execution of the Remote Monitoring and Management tool Atera.
- 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
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.
- Effort: advanced
TOR Usage
Detects TOR usage, based on the IP address and the destination port (filtered on NTP). 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
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.
