./HAVOC Lambda Functions

Details about AWS Lambda functions created in a ./HAVOC deployment

Suggest Edits

When creating a new ./HAVOC deployment, a series of AWS Lambda functions are created in your AWS account. Below is a list of the Lambda functions and their environment variables.

The Terraform configuration file that is used to create the lambda functions is available here: https://github.com/havocsh/havoc/blob/main/havoc_deploy/aws/terraform/lambdas.tf

AWS Lambda Permissions

  • Permissions are defined to allow various AWS services to invoke the Lambda functions. These services include API Gateway, CloudWatch, and AWS Events.
  • The source ARNs and principals are defined per permission, ensuring that only the specified services can invoke the Lambda functions.
