How to bruteforce monitoring and security apps with Hydra and the Password Auditor

Every CMS and e-commerce platform handles authentication differently, with varying levels of protection like rate limiting, CAPTCHAs, and account lockouts. This guide provides real-world testing methodologies for WordPress, Drupal, Joomla, PrestaShop, and Magento, helping you correctly identify weak login endpoints, analyze error messages, and work around security mechanisms for efficient pentests and security assessments.

You’ll find detailed Hydra commands for precise, high-efficiency bruteforcing, along with insights on using our Password Auditor to automate credential testing. This comparison makes it easier to choose which tool can help you brute-forcing faster and more effectively by capturing screenshots of logged-in sessions and generating detailed proof of valid credentials.

How to check Zabbix for weak credentials

Deployment method: Docker compose - docker-compose_v3_ubuntu_pgsql_latest.yaml

1. Find the Zabbix web app login endpoint

Usually, you can find the Zabbix login form on the / endpoint on port 80 or 443.

2. Discover the Zabbix login parameters

Use the Network tab in Web Developer Tools to identify the parameters.

3. Identify error messages and protection mechanisms

After one invalid attempt, Zabbix returns the following message:

Zabbix login error

After 5 incorrect credentials, the user gets temporarily blocked. From our tests, the lock duration was about 5 minutes.

Hydra commands and output

In the first 1 set of valid and 1 set of invalid credentials scenario, we used the following Hydra commands:

hydra -s 80 -l Admin -p test zabbix.pentest-ground.com http-post-form "/index.php:name=^USER^&password=^PASS^&autologin=1&enter=Sign+in:Incorrect user name or password or account is temporarily blocked." -V
hydra -s 80 -l Admin -p zabbix zabbix.pentest-ground.com http-post-form "/index.php:name=^USER^&password=^PASS^&autologin=1&enter=Sign+in:Incorrect user name or password or account is temporarily blocked." -V
Zabbix Hydra output

Hydra successfully identified the valid credentials.


For the second, more realistic scenario, we used the following command:

hydra -s 80 -L users.txt -P pass.txt zabbix.pentest-ground.com http-post-form "/index.php:name=^USER^&password=^PASS^&autologin=1&enter=Sign+in:Incorrect user name or password or account is temporarily blocked." -V
Zabbix Hydra output multiple credentials

Hydra identified the valid credentials, when 2 users and 13 passwords were tested.

Password Auditor commands and results

For the first scenario, these are the parameters we adjusted to perform a more focused scan:


The pa-benchmark wordlist includes valid credentials, so the process involves making four attempts to the target: 3 with invalid credentials and 1 with valid credentials.


The screenshots below show that the Pentest-Tools.com Password Auditor successfully identified the valid credentials.

The Password Auditor also provides a screenshot of the logged-in session to verify the validity of the provided credentials.

For the second scenario, we modified the wordlist to include 2 users (1 invalid and 1 valid) and 12 passwords (11 invalid and 1 valid). 

Zabbix Password Auditor scan findings

Because of the temporary lockout mechanism, the Pentest-Tools.com Password Auditor couldn’t identify the valid credentials with 2 users and 12 passwords.
