Think Hydra is powerful? Wait until you see how parallel attacks will skyrocket your cracking speed in Termux.
When I first started diving into ethical hacking, brute forcing FTP, SSH, and web logins seemed like an endless, painstaking process. Each test required waiting for ages before results came in, and the sheer volume of passwords to test made it even worse. But then, I stumbled upon Hydra’s parallel attacks—an absolute game-changer. With the ability to run multiple password-cracking threads simultaneously, Hydra turned those long waits into mere seconds. No longer did I have to sit idly by while Hydra worked through its tasks. The beauty of parallel attacks was instantly clear to me: faster, more efficient, and even more powerful.
If you’re tired of watching your brute force efforts crawl at a snail’s pace and want to speed up your ethical hacking game, this guide is for you.
Ready to get those results in record time?
Read on to find out how you can leverage Hydra’s parallel attacks to transform your hacking speed in Termux.

Explanation of Hydra’s Parallel Attack Mechanism
Hydra’s parallel attacks are one of the key features that set it apart from other brute-force tools. But what exactly does this mean, and why is it a game-changer?
Parallel attacks allow Hydra to test multiple passwords across multiple connections at the same time. Instead of sequentially testing one password at a time (which can be slow, especially for large password lists), Hydra splits the workload into several “threads.” Each thread tests a set of possible passwords independently of the others. This means Hydra can try many passwords at once, dramatically reducing the time it takes to crack an account or system.
For example, instead of Hydra testing passwords one by one for a single FTP server, you could set up Hydra to simultaneously attack several FTP servers at once, or use multiple threads on one server to crack multiple accounts. This parallelization boosts the cracking process, making it faster and more efficient.
The real advantage? You’re optimizing your time and resources. When you run a brute-force attack across several threads, you’re leveraging your machine’s full potential and speeding up the attack. Parallel attacks give ethical hackers the ability to cover more ground without spending hours or days on a single system.
Running a Multi-Threaded Hydra Attack
To run a multi-threaded Hydra attack, use the -t option followed by the number of threads you want to use. In the following example, we’ll set up a brute-force attack against an FTP server using four parallel threads:
hydra -l admin -P /path/to/passwordlist.txt -t 4 ftp://192.168.1.10In this command:
-l adminspecifies the username to test.-P /path/to/passwordlist.txtuses the specified password list for the brute-force attack.-t 4sets the number of threads (in this case, four).ftp://192.168.1.10is the target FTP service.
Analyzing Hydra Parallel Output
After running the above command, Hydra will show output like this:
[21][ftp] host: 192.168.1.10 login: admin password: admin123
[22][ftp] host: 192.168.1.10 login: admin password: 123456This output indicates that Hydra used multiple threads to test different passwords simultaneously. Each line represents an attempt made by one of the threads:
- [21] and [22] represent the attempts made by different threads.
- The correct credentials are displayed once a valid combination is found.
Using parallel attacks shortens the overall time to crack the password by increasing the number of attempts Hydra can handle at any given moment.
Adjusting the Number of Threads
Depending on your system’s performance and the network’s bandwidth, you can adjust the number of threads. For instance, if you want to run eight threads, modify the command as follows:
hydra -l admin -P /path/to/passwordlist.txt -t 8 ftp://192.168.1.10Increasing the number of threads will speed up the attack, but be mindful of your system’s capabilities. Too many threads can overload your network or the target server, potentially causing timeouts or errors.
Troubleshooting Parallel Attacks
When running multi-threaded attacks, you may encounter errors or connection issues due to the high number of requests being sent simultaneously. Here are a few common problems you might see:
- Timeout Errors:csharpCopy code
[ERROR] target 192.168.1.10 timed out, retrying...This error often happens when the server cannot handle the volume of requests. Reducing the number of threads can alleviate this issue. - Connection Refused:csharpCopy code
[ERROR] target 192.168.1.10 connection refused.This occurs when the server has blocked your IP due to too many connection attempts. Using a VPN or adjusting the delay between attempts can help bypass this issue.
To avoid these errors, you can experiment with thread counts and delays to find a balance between speed and stability.

Saving Output for Further Analysis
Hydra allows you to save the output of parallel attacks for future reference. This is particularly useful when testing large networks or multiple services over time. Use the -o option to save the output:
hydra -l admin -P /path/to/passwordlist.txt -t 4 -o hydra_parallel_output.txt ftp://192.168.1.10Now, all of the results from the attack will be saved in the hydra_parallel_output.txt file, allowing you to analyze the Hydra output later.

Potential Pitfalls and Ethical Considerations
While Hydra is a powerful tool, it’s crucial to remember that it is meant to be used responsibly. Ethical hacking means conducting tests with explicit permission from the system owners. Here’s why this matters:
- Permission is Key
Brute-force attacks, even on your own network, can disrupt service and damage system performance. Always ensure you have written consent from the system owner or administrator before attempting any form of penetration testing. - Legal Boundaries
Unauthorized hacking, even if done with good intentions, can lead to severe legal consequences. You could be held liable for any damage caused during an unauthorized attack, whether it’s intentional or not. Ethical hackers must follow legal guidelines, such as obtaining consent and conducting responsible testing. - Impact of Brute Force Attacks
While Hydra’s parallel attacks make password cracking faster and more efficient, they also increase the potential for disruption. When running a parallel attack, your device can overwhelm the server with multiple login attempts at once. This could potentially lead to the server temporarily blocking access or triggering security measures like IP blacklisting.
By keeping these considerations in mind, you can ensure that you’re using Hydra responsibly and ethically.
