## EC2 & Related Services

Check in this page more information about this:

{% content-ref url="../aws-services/aws-ec2-ebs-elb-ssm-vpc-and-vpn-enum/" %}
[aws-ec2-ebs-elb-ssm-vpc-and-vpn-enum](../aws-services/aws-ec2-ebs-elb-ssm-vpc-and-vpn-enum/)
{% endcontent-ref %}

### Public Ports

It's possible to expose the **any port of the virtual machines to the internet**. Depending on **what is running** in the exposed the port an attacker could abuse it.

#### SSRF

### Public AMIs & EBS Snapshots

AWS allows to **give access to anyone to download AMIs and Snapshots**. You can list these resources very easily from your own account:

{% code overflow="wrap" %}
```bash
# Public AMIs
aws ec2 describe-images --executable-users all

## Search AMI by ownerID
aws ec2 describe-images --executable-users all --query 'Images[?contains(ImageLocation, `967541184254/`) == `true`]'

## Search AMI by substr ("shared" in the example)
aws ec2 describe-images --executable-users all --query 'Images[?contains(ImageLocation, `shared`) == `true`]'

# Public EBS snapshots (hard-drive copies)
aws ec2 describe-snapshots --restorable-by-user-ids all
aws ec2 describe-snapshots --restorable-by-user-ids all | jq '.Snapshots[] | select(.OwnerId == "099720109477")'
```
{% endcode %}

If you find a snapshot that is restorable by anyone, make sure to check [AWS - EBS Snapshot Dump](https://cloud.hacktricks.xyz/pentesting-cloud/aws-security/aws-post-exploitation/aws-ec2-ebs-ssm-and-vpc-post-exploitation/aws-ebs-snapshot-dump) for directions on downloading and looting the snapshot.

#### Public URL template

```bash
# EC2
ec2-{ip-seperated}.compute-1.amazonaws.com
# ELB
http://{user_provided}-{random_id}.{region}.elb.amazonaws.com:80/443
https://{user_provided}-{random_id}.{region}.elb.amazonaws.com
```

### Enumerate EC2 instances with public IP

{% code overflow="wrap" %}
```bash
aws ec2 describe-instances --query "Reservations[].Instances[?PublicIpAddress!=null].PublicIpAddress" --output text
```
{% endcode %}
