## ECR

### Public registry repositories (images)
|
|
|
|
As mentioned in the ECS Enum section, a public registry is **accessible by anyone** uses the format **`public.ecr.aws/<random>/<name>`**. If a public repository URL is located by an attacker he could **download the image and search for sensitive information** in the metadata and content of the image.
|
|
|
|
{% code overflow="wrap" %}
|
|
```bash
|
|
aws ecr describe-repositories --query 'repositories[?repositoryUriPublic == `true`].repositoryName' --output text
|
|
```
|
|
{% endcode %}
|
|
|
|
{% hint style="warning" %}
|
|
This could also happen in **private registries** where a registry policy or a repository policy is **granting access for example to `"AWS": "*"`**. Anyone with an AWS account could access that repo.
|
|
{% endhint %}
|
|
|
|
### Enumerate Private Repo
|
|
|
|
The tools [**skopeo**](https://github.com/containers/skopeo) and [**crane**](https://github.com/google/go-containerregistry/blob/main/cmd/crane/doc/crane.md) can be used to list accessible repositories inside a private registry.
|
|
|
|
```bash
|
|
# Get image names
|
|
skopeo list-tags docker://<PRIVATE_REGISTRY_URL> | grep -oP '(?<=^Name: ).+'
|
|
crane ls <PRIVATE_REGISTRY_URL> | sed 's/ .*//'
|
|
```
