|
## boto3 IAM API
|
|
|
|
```python
|
|
import boto3
|
|
|
|
iam = boto3.client("iam")
|
|
|
|
# Download full account authorization details
|
|
paginator = iam.get_paginator("get_account_authorization_details")
|
|
for page in paginator.paginate():
|
|
users = page["UserDetailList"]
|
|
roles = page["RoleDetailList"]
|
|
policies = page["Policies"]
|
|
|
|
# Get specific policy version
|
|
policy = iam.get_policy_version(
|
|
PolicyArn="arn:aws:iam::123456789012:policy/MyPolicy",
|
|
VersionId="v2"
|
|
)
|
|
```

pip install cloudsplaining
|
|
|
|
# Download account authorization details
|

|
|

# Scan authorization file for privilege escalation
|
|
cloudsplaining scan --input-file default.json --output results/

|
|
# Scan a single policy file

|
cloudsplaining scan-policy-file --input-file policy.json
|
