GuardDuty

Overview

AWS GuardDuty is a service that detects potential security issues within your network.

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: intermediate
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: advanced
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
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
RYUK Ransomeware - martinstevens Username

Detects user name "martinstevens". Wizard Spider is used to add the user name "martinstevens" to the AD of its victims. It was observed in several campaigns; in 2019 and 2020.

  • Effort: elementary
SEKOIA.IO Intelligence Feed

Detect threats based on indicators of compromise (IOCs) collected by SEKOIA's Threat and Detection Research team.

  • Effort: elementary
Telegram Bot API Request

Detects suspicious DNS queries to api.telegram.org used by Telegram Bots of any kind

  • Effort: advanced

Configure

Prerequisites

Create a S3 bucket

Your GuardDuty findings will be collected in an Amazon S3 bucket.

To set up the bucket, please refer to this guide.

Prerequisites

  • An administator access to the Amazon console with the permission to create SQS queue and S3 notifications.
  • A self managed AWS S3 bucket where events will be published prior to be consumed by Sekoia.io.

Create a SQS queue

This integration relies on S3 Event Notifications (SQS) to discover new S3 objects.

To enable the S3 Event Notification:

  1. Create a queue in the SQS service by following this guide
  2. 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:*",
          "Resource": "arn:aws:sqs:XXX:XXX"
        }
      ]
    }
    

Note

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 and then:

  1. Select the notification for object creation in the Event type section
  2. As the destination, choose the SQS service
  3. 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:

  1. In your AWS console, navigate to: Services > GuardDuty > Settings
  2. Go to the Finding export options section
  3. Select the bucket you created previously. Ensure your bucket policy allows GuardDuty to add new objects
  4. Select or create a key for the KMS encryption
  5. Click the button Save

Create the intake

Go to the intake page and create a new intake from the format AWS GuardDuty.

Pull events

To start to pull events, you have to:

  1. Go to the playbook page and create a new playbook with the AWS Fetch new logs on S3 connector
  2. Set up the module configuration with the AWS Access Key, the secret key and the region name. Set up the trigger configuration with the name of the SQS queue as well as the intake key from the intake previously created
  3. Start the playbook and enjoy your events
