What is the primary function of THC Hydra?

  1. Recover lost files

  2. Crack passwords of network services

  3. Reset Windows administrator passwords

  4. Perform network audits

The correct answer is: Crack passwords of network services

The primary function of THC Hydra is to crack passwords of network services. It is a popular and powerful tool used in ethical hacking to test the strength of passwords across various network services and protocols. By utilizing a technique known as brute force, THC Hydra can attempt numerous combinations of usernames and passwords until it successfully gains access to a target service. This capability makes THC Hydra especially useful in penetration testing scenarios, allowing security professionals to identify weak passwords that could be exploited by malicious actors. The tool supports a wide range of protocols, including HTTP, FTP, SSH, and many others, reflecting its versatility in addressing different types of network security vulnerabilities. Options that involve recovering lost files, resetting Windows administrator passwords, or performing network audits do not directly pertain to the primary capabilities of THC Hydra, as these functions align more closely with different tools and methodologies within the realm of cybersecurity.
