Core Function: AzureHound is a data collector that enumerates objects and relationships within a Microsoft Azure environment to be ingested and analyzed by BloodHound.
Primary Use-Cases:
Mapping complex Azure Active Directory (Azure AD) and Resource Manager privilege relationships.
Identifying privilege escalation paths and attack vectors within Azure tenants.
Auditing Azure configurations for security misconfigurations and overly permissive roles.
Assisting in red team and penetration testing engagements by visualizing the target environment.
Enhancing defensive capabilities by understanding potential compromise routes.
Penetration Testing Phase: Information Gathering & Enumeration.
Brief History: AzureHound was developed as a necessary extension to the original BloodHound project, which focused exclusively on on-premises Active Directory. As organizations increasingly adopted cloud infrastructure, the SpecterOps team created AzureHound to provide the same powerful attack path mapping capabilities for the Microsoft Azure cloud ecosystem, bridging the gap between on-prem and cloud security analysis.
This section covers the basic commands for ensuring AzureHound is correctly installed and ready for operation on your system. All actions must be performed on systems and networks you are explicitly authorized to test.
Before attempting to install, it's good practice to check if the tool is already present and in your system's PATH.

Command Breakdown:
azurehound list: The data collection command.
--tenant '...': Specifies the GUID of the Azure tenant to target. This overrides any tenant set in the configuration file.
Ethical Context & Use-Case: This is a critical command for consultants who work across multiple client environments. Explicitly defining the tenant ID for each command is a best practice that prevents accidental data collection from the wrong client tenant, which would be a serious breach of engagement rules.
--> Expected Output:
INFO[0000] Starting AzureHound v2.4.1 INFO[0000] Authenticating... INFO[0015] Successfully authenticated to Azure INFO[0015] Enumerating subscriptions... INFO[0016] Found 2 subscriptions INFO[0016] Starting enumeration for tenant b6528b1a-31e8-46f9-b7b8-f0931223c83f INFO[0018] [1/10] Enumerating Users... ... INFO[0140] Writing output files... INFO[0141] AzureHound data collection finished. Ingest the generated JSON files into BloodHound.
Perform a full collection using a pre-acquired JSON Web Token (JWT) for authentication.
Command:
Bash
azurehound list -j 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c'
Command Breakdown:
azurehound list: The data collection command.
-j or --jwt: The flag to provide a JWT for authentication.
'...': The actual JWT string.
Ethical Context & Use-Case: In some testing scenarios, you might obtain a JWT through other means (e.g., from a compromised application or user session). This flag allows you to leverage that token to perform enumeration with AzureHound, simulating how an attacker would pivot using stolen credentials. This is used to test the impact of a token compromise.
--> Expected Output:
INFO[0000] Starting AzureHound v2.4.1 INFO[0000] Attempting to authenticate with provided JWT... INFO[0001] Successfully authenticated to Azure INFO[0001] Starting enumeration for tenant b6528b1a-31e8-46f9-b7b8-f0931223c83f ... INFO[0120] Writing output files... INFO[0121] AzureHound data collection finished.
Perform a full collection using a pre-acquired refresh token for more persistent access.
Command:
Bash
azurehound list -r '0.ARwA6...[long refresh token string]...1'
Command Breakdown:
azurehound list: The data collection command.
-r or --refresh-token: The flag to provide a refresh token for authentication.
'...': The actual refresh token string.
Ethical Context & Use-Case: Refresh tokens are longer-lived than access tokens (JWTs). During a penetration test, if you acquire a refresh token, it represents a more significant level of access. Using this flag helps demonstrate the risk associated with refresh token theft by showing the extent of data an attacker could collect with it.
--> Expected Output:
INFO[0000] Starting AzureHound v2.4.1 INFO[0000] Attempting to authenticate with provided refresh token... INFO[0002] Successfully authenticated to Azure INFO[0002] Starting enumeration for tenant b6528b1a-31e8-46f9-b7b8-f0931223c83f ... INFO[0125] Writing output files...

Run a collection with the most detailed logging possible, including trace-level information.
Command:
Bash
azurehound list -v 2
Command Breakdown:
azurehound list: The data collection command.
-v 2: Sets the verbosity level to the maximum.
Ethical Context & Use-Case: This level of verbosity is reserved for deep troubleshooting during an authorized test. For example, if you suspect a Web Application Firewall (WAF) or conditional access policy is interfering with your enumeration, the trace-level logs from -v 2 can provide the raw request/response data needed to identify and understand the blocking mechanism.
--> Expected Output:
INFO[0000] Starting AzureHound v2.4.1 DEBU[0000] Using default configuration path: /root/.config/azurehound/config.json DEBU[0000] No JWT or Refresh Token provided. Using device code flow.

Execute a collection and redirect all log messages to a specified file for later review.
Command:
Bash
azurehound list --log-file azurehound_run.log
Command Breakdown:
azurehound list: The data collection command.
--log-file azurehound_run.log: Specifies that all console output (INFO, DEBUG, etc.) should be written to the file azurehound_run.log instead of the terminal.
Ethical Context & Use-Case: Maintaining a detailed audit trail is a core requirement of professional penetration testing. This command ensures that a complete record of the enumeration process, including timestamps and any errors, is saved. This log file becomes part of the evidence and can be used for reporting and for correlating activities with the client's security monitoring systems.
--> Expected Output:
(No output will be displayed on the terminal. All logs are written to the file.)
(After completion, cat azurehound_run.log would show the standard log output.)
Execute a collection where the log output is structured as JSON, which is useful for machine parsing.
Command:
Bash
azurehound list --json
Command Breakdown:
azurehound list: The data collection command.
--json: A flag that changes the log output from plain text to a structured JSON format.
Ethical Context & Use-Case: When integrating security testing tools into a larger automated workflow or sending logs to a Security Information and Event Management (SIEM) system, structured logs are essential. This command formats the output so it can be easily ingested and parsed by other programs, allowing for automated monitoring and analysis of the penetration testing process itself.

azurehound start: The command to run AzureHound in service mode.
-c or --config: Specifies the path to a configuration file.
Content of /etc/azurehound/bhe_config.json:
JSON
{
"bhe_url": "https://bloodhound.internal.corp",
"bhe_token": "collector_token_string",
"tenant": "b6528b1a-31e8-46f9-b7b8-f0931223c83f"
}
Ethical Context & Use-Case: When deploying collectors in a production environment for defensive monitoring, placing secrets like tokens in command-line history is a security risk. This method uses a configuration file with restricted permissions, which is the professionally accepted standard for securely deploying collection agents. It prevents sensitive credentials from being exposed.

This section demonstrates how to chain AzureHound with other standard command-line tools to perform advanced, on-the-fly analysis of the collected data. This elevates the tool from a simple collector to a powerful component in a larger analysis toolchain.
Perform a user enumeration and immediately pipe the JSON output to jq to extract a clean list of all User Principal Names (UPNs).
Command:
Bash
azurehound list --users && jq '.data[].Properties.userprincipalname' 20*.json | sed 's/"//g'
Command Breakdown:
azurehound list --users: Collects all user data and saves it to a timestamped JSON file.
&&: Executes the next command only if the first one succeeds.
jq '.data[].Properties.userprincipalname' 20*.json: A jq command to parse the newly created JSON file.
.data[]: Enters the main data array.
.Properties.userprincipalname: Selects the value of the userprincipalname key for each object.
| sed 's/"//g': Pipes the output to sed to remove the quotation marks from the resulting strings.
Ethical Context & Use-Case: During an assessment, you may need a quick list of all users in the target environment to use as input for another tool (e.g., a password sprayer, within an authorized scope). This command chain is incredibly efficient, turning raw JSON data into a clean, usable list of usernames without needing to manually open and parse the file.

Collect tenant role data and use grep and jq to identify members of the highly privileged "Global Administrator" role.
Command:
Bash
azurehound list --rbac && cat 20*.json | jq '.data[] | select(.RoleName == "Global Administrator") | .Members[]'
Command Breakdown:
azurehound list --rbac: Collects all RBAC and tenant role data.
&&: Ensures the collection finishes before parsing.
cat 20*.json: Concatenates the output JSON files.
| jq '...': Pipes the JSON data to jq for filtering.
.data[]: Enters the data array.
select(.RoleName == "Global Administrator"): Filters the data to only include the object representing the Global Administrator role.
.Members[]: Selects each item from the Members array within that role object.
Ethical Context & Use-Case: Identifying who holds the highest privileges is a primary goal in any Azure security audit. This command chain immediately answers the question, "Who are the Global Admins?". This allows an ethical hacker to focus their attention on these accounts, assessing their security hygiene (e.g., MFA status) as they represent the most impactful targets for a potential attacker.

Collect user data and use jq to filter for enabled accounts, then use wc to count them.
Command:
Bash
azurehound list --users && cat 20*.json | jq '.data[] | select(.Properties.accountenabled == true)' | wc -l
Command Breakdown:
azurehound list --users: Collects all user data.
&&: Executes the next command upon success.
cat 20*.json: Reads the output file.
| jq '.data[] | select(.Properties.accountenabled == true)': Pipes the data to jq, which filters the user objects to only include those where the accountenabled property is true.
| wc -l: Pipes the resulting JSON objects (one per line) to the wc (word count) command with the -l flag to count the number of lines, effectively counting the enabled users.
Ethical Context & Use-Case: Understanding the true attack surface involves knowing the number of active, enabled accounts. This is important for scoping a penetration test and for defenders to understand their environment. This command provides a quick, accurate metric that can be compared against expected employee counts to identify potentially orphaned or unnecessary active accounts.

AzureHound produces structured data that is perfect for analysis by more advanced scripts. Here, we'll use Python with the Pandas library—a cornerstone of data science and AI—to derive insights that go beyond simple command-line queries.
Use Python and Pandas to parse the AzureHound groups JSON file and generate a report of the top 10 users based on their number of group memberships.
Script (analyze_groups.py):
Python
import json
import pandas as pd
from collections import Counter
# Load the AzureHound group data file
file_path = '202508170228_azure_groups.json'
with open(file_path, 'r') as f:
data = json.load(f)
memberships = []
for group in data.get('data', []):
for member in group.get('Members', []):
# We only care about user members for this analysis
if member.get('ObjectType') == 'User':
memberships.append(member.get('MemberName'))
# Count memberships for each user
membership_counts = Counter(memberships)
# Create a Pandas DataFrame for analysis and display
df = pd.DataFrame(membership_counts.items(), columns=['UserPrincipalName', 'GroupCount'])
df = df.sort_values(by='GroupCount', ascending=False)
print("Top 10 Users by Group Membership:")
print(df.head(10).to_string(index=False))
Command:
Bash
azurehound list --groups && python3 analyze_groups.py
Command Breakdown:
azurehound list --groups: Generates the necessary _azure_groups.json file.
&& python3 analyze_groups.py: Executes the Python script to perform the analysis. The script loads the JSON, iterates through all groups, counts user memberships, and uses Pandas to display a sorted top-10 list.
Ethical Context & Use-Case: An AI-powered approach can uncover subtle patterns. A user who is a member of an unusually high number of groups can be a security risk. This might indicate a "privilege collector" account that has accumulated permissions over time and is not being properly managed. This script automatically flags these high-risk accounts for a security analyst to investigate further as part of a comprehensive posture assessment.

Use Python and Pandas to cross-reference Key Vault data with Service Principal data to identify non-user principals that have permissions to read secrets.
Script (find_sp_secrets_access.py):
Python
import json
import pandas as pd
# Load the necessary AzureHound data
try:
with open('202508170229_azure_keyvaults.json', 'r') as f:
keyvault_data = json.load(f)
except FileNotFoundError:
print("Error: Key Vault data file not found. Run 'azurehound list --keyvaults'.")
exit()
sp_access_list = []
for vault in keyvault_data.get('data', []):
vault_name = vault.get('Name')
for policy in vault.get('AccessPolicies', []):
# Check if the principal has 'get' or 'list' permissions on secrets
has_secret_perms = any(p in policy.get('Permissions', {}).get('Secrets', []) for p in ['get', 'list', 'all'])
# We only care about Service Principals (not Users or Groups here)
if policy.get('PrincipalType') == 'ServicePrincipal' and has_secret_perms:
sp_access_list.append({
'ServicePrincipal': policy.get('PrincipalName'),
'KeyVault': vault_name,
'SecretPermissions': policy.get('Permissions', {}).get('Secrets', [])
})
if not sp_access_list:
print("No Service Principals with secrets access found.")
else:
# Use Pandas to display the results in a clean table
df = pd.DataFrame(sp_access_list)
print("Service Principals with Key Vault Secret Access:")
print(df.to_string(index=False))
Command:
Bash
azurehound list --keyvaults && python3 find_sp_secrets_access.py
Command Breakdown:
azurehound list --keyvaults: Generates the _azure_keyvaults.json file.
&& python3 find_sp_secrets_access.py: Executes the Python script. The script parses the key vault data, specifically looking for access policies granted to Service Principals that include permissions to read secrets, and presents the findings in a structured table.
Ethical Context & Use-Case: Automated services (Service Principals) with access to secrets are a major target for attackers, as their credentials can often be found in code repositories or configuration files. This AI-augmented analysis automates the critical task of identifying these non-human identities with access to sensitive data. For a security professional, this report provides a prioritized list of credentials to secure and permissions to review, directly improving the security posture of the authorized environment.
