# AWS - SQS Persistence

## SQS
|
||||

|
||||
### 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"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
> [!NOTE]
|
||||
> 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)
