IMDShift: Prevent SSRF attacks on AWS EC2

by ddos · February 14, 2025

IMDShift

AWS workloads that rely on the metadata endpoint are vulnerable to Server-Side Request Forgery (SSRF) attacks. IMDShift automates the migration process of all workloads to IMDSv2 with extensive capabilities, which implements enhanced security measures to protect against these attacks.

Features

Detection of AWS workloads that rely on the metadata endpoint amongst various services which includes – EC2, ECS, EKS, Lightsail, AutoScaling Groups, Sagemaker Notebooks, Beanstalk (in progress)
Simple and intuitive command-line interface for easy usage
Automated migration of all workloads to IMDSv2
Standalone hop limit update for compatible resources
Standalone metadata endpoint enable operation for compatible resources
Detailed logging of migration process
Identify resources that are using IMDSv1, using the MetadataNoToken CloudWatch metric across specified regions
Built-in Service Control Policy (SCP) recommendations

IMDShift vs. Metabadger

Metabadger is an older tool that was used to facilitate the migration of AWS EC2 workloads to IMDSv2.

IMDShift makes several improvements to Metabadger’s capabilities:

IMDShift allows the migration of standalone services and not all EC2 instances, blindly. For example, the user can choose to only migrate EKS workloads, also some services such as Lightsail, do not fall under the EC2 umbrella, and IMDShift has the capability to migrate such resources as well.
IMDShift allows standalone enabling of metadata endpoint for resources it is currently disabled, without having to perform migration on the remaining resources
IMDShift allows standalone update response hop limit for resources where metadata endpoint is enabled, without having to perform migration on the remaining resources
IMDShift allows, not only the option to include specific regions but also skip specified regions
IMDShift not only allows usage of AWS profiles but also can assume roles, to work
IMDShift helps with post-migration activities, by suggesting various Service Control Policies (SCPs) to implement.
