## SQS
For more information check:

### Using resource policy
In SQS you need to indicate with an IAM policy **who has access to read and write**. It's possible to indicate external accounts, ARN of roles, or **even "\*"**.\
The following policy gives everyone in AWS access to everything in the queue called **MyTestQueue**:
```json
{
"Version": "2008-10-17",
"Id": "__default_policy_ID",
"Statement": [
{
"Sid": "__owner_statement",
"Effect": "Allow",
"Principal": {
"AWS": "*"
},
"Action": [
"SQS:*"
],
"Resource": "arn:aws:sqs:us-east-1:123123123123:MyTestQueue"
}
]
}
```
{% hint style="info" %}
You could even **trigger a Lambda in the attackers account every-time a new message** is put in the queue (you would need to re-put it) somehow. For this follow these instructinos: [https://docs.aws.amazon.com/lambda/latest/dg/with-sqs-cross-account-example.html](https://docs.aws.amazon.com/lambda/latest/dg/with-sqs-cross-account-example.html)
