Callback URLs have a wide range of applications in modern web development, including: The URL you provided, http://169
The above might look like a broken string, but in the context of a cloud environment, it is a potent command. That string, often garbled by URL encoding (`http-3A-2F-2F169.254...`), is the key to a cloud kingdom. It points directly to the **AWS Instance Metadata Service (IMDS)**, the internal service that hands out the keys to your entire cloud infrastructure.
By understanding the anatomy of this attack and implementing a layered defense, you can close the door on one of the most common and destructive cloud attack vectors. Remember: in the cloud, every internal endpoint is just one misconfigured request away from public exposure. Remember: in the cloud, every internal endpoint is
