Similar to bucket policies, ACLs can be used to restrict/allow access to buckets and objects. A misconfigured bucket/object ACL can allow attackers to steal sensitive data and use the S3 bucket in other attacks.
In this lab, the ACLs allow reading the object but do not allow listing objects. There exists a misconfiguration in bucket ACL which can be leveraged to modify the ACL and identify the object.
Objective: Interact with the S3 bucket and retrieve the flag.

Technical Support for this Lab:
There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!
We currently provide technical support limited to:
- Giving hints for a lab exercise
- In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
- A lab exercise fails to load or has errors in it
If you need technical support, please email email@example.com clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
For adminitrative queries, billing, enterprise accounts etc. please email firstname.lastname@example.org
