Enable Amazon GuardDuty:

GuardDuty is a threat detection service that natively supports detecting cryptocurrency mining activity on Amazon EC2 instances.

Enable GuardDuty for the account and all AWS Regions to ensure comprehensive coverage.

Monitor GuardDuty Findings:

GuardDuty generates findings for activities associated with cryptocurrency mining (e.g., unauthorized mining, DNS queries to known mining domains).

Create an EventBridge Rule:

Define an EventBridge rule that triggers on specific GuardDuty findings related to cryptocurrency activity.

Configure the rule to send notifications to an Amazon SNS topic.

Example Rule:

{

"Source": ["aws.guardduty"],

"DetailType": ["GuardDuty Finding"],

"Detail": {

"type": ["CryptoCurrency:EC2/BitcoinTool.B"]

}

}

Advantages of GuardDuty:

Automated Threat Detection: Requires no additional setup or custom rules.

Near-Real-Time Alerts: Delivers findings and notifications with minimal delay.
