How Green Hat Hackers Help Secure Mobile Apps

For Android or iOS developers looking to enhance the security of their applications, engaging with green hat hackers can offer several benefits:

  • Bug Identification: Green hat hackers can assist in identifying common vulnerabilities and bugs in applications. They might not possess the sophisticated skills of experienced hackers, but they can still find fundamental issues like input validation flaws or insecure data storage practices.
  • Feedback from a Learning Perspective: These hackers may provide valuable feedback from a beginner’s perspective. They can offer insights into how a less experienced individual might attempt to exploit vulnerabilities, which can be informative for developers in understanding potential attack vectors.
  • Test Environment: Developers can provide them with specific versions or sections of their applications to test, creating a controlled environment for learning and identifying security gaps.
  • User Perspective: Green hat hackers can provide a fresh perspective on an application’s user interface and user experience, pointing out potential security issues that might arise from design or functionality choices.

However, it’s essential to approach this collaboration cautiously:

  • Legal and Ethical Boundaries: Ensure that any interaction with hackers complies with legal and ethical standards. Engage with them in a controlled environment and with appropriate agreements to protect both parties.
  • Limited Expertise: While green hat hackers can identify basic vulnerabilities, they might not have the depth of knowledge to recognize more complex security flaws. Supplement their findings with professional security audits or penetration testing by experienced professionals.

Engaging with green hat hackers can be valuable to an overall security strategy. Still, it should be only one component among many others, such as code reviews, automated security testing, and professional security assessments.

Popular Green Hat Hacker Strategies for Learning about Hacking and Mobile Cybersecurity

There are many online resources for learning about mobile hacking and cybersecurity. Many resources are free, and some offer interactive tools to develop and practice hacking skills.

  • Online Courses and Tutorials: Platforms like CourseraUdemy, and Cybrary offer courses specifically focused on mobile device security. Look for courses covering mobile app penetration testing, secure platform coding, and mobile device security fundamentals.
  • Books and Documentation: Explore books on mobile security, such as “The Mobile Application Hacker’s Handbook” by Dominic Chell and “iOS Application Security” by David Thiel. Refer to official documentation from Apple and Google regarding their mobile platform security guidelines and best practices.
  • Capture The Flag (CTF) Challenges: Participate in mobile-specific CTF challenges and competitions. Platforms like Hack The Box and OverTheWire offer mobile-focused challenges. These challenges simulate real-world scenarios and help understand mobile device vulnerabilities.
  • Online Communities and Forums: Join online communities and forums like Reddit’s r/netsec and GitHub repositories focused on mobile security. Engage with others, ask questions, and share knowledge to learn from the experiences of seasoned professionals.
  • Practice on Test Devices and Emulators: Experiment with vulnerable mobile applications or intentionally insecure test environments designed for learning. Use mobile device emulators or acquire inexpensive older devices to practice hacking techniques without risking a live production environment.
  • Attend Workshops and Webinars: Look for workshops or webinars conducted by cybersecurity professionals or organizations specializing in mobile security. These events often provide hands-on experience and practical insights into securing mobile applications.
  • Contribute to Open Source Projects: Contribute to open-source projects related to mobile security on platforms like GitHub. Review code, suggest improvements, or find and fix vulnerabilities to gain practical experience.
  • Stay Updated and Analyze Security Research: Follow reputable blogs, security news sites, and academic research papers on mobile security to stay updated with the latest trends and vulnerabilities. Analyze security advisories and reports related to mobile platforms to understand common vulnerabilities and their mitigations.

Remember, hands-on practice and continuous learning are crucial in cybersecurity. Experiment ethically, respect privacy and laws, and always focus on responsible disclosure when discovering vulnerabilities in real applications or systems.

Green Hat Hackers Vs. Other Types of Hackers

Here’s a comparison of a green hat hacker with six other major types of hackers:

Black Hat Hacker

  • Intent: Black hat hackers have malicious intent. They exploit vulnerabilities for personal gain, financial profit, or to cause harm.
  • Skills: Highly skilled and knowledgeable in various hacking techniques.
  • Activities: Engage in illegal activities like stealing data, spreading malware, or disrupting systems.

White Hat Hacker (Ethical Hacker)

  • Intent: White hat hackers work ethically, aiming to improve security. They use their skills to find vulnerabilities and help organizations improve their defenses.
  • Skills: Skilled in hacking techniques but use their knowledge for defensive purposes.
  • Activities: Conduct security assessments and penetration testing and help fix vulnerabilities.

Gray Hat Hacker

  • Intent: Gray hat hackers fall between black hat and white hat hackers. They may break into systems without permission but not with malicious intent.
  • Skills: Similar technical skills as black hat hackers but often lack malicious intent.
  • Activities: Might disclose vulnerabilities they find without permission, which can be illegal.

Script Kiddie

  • Intent: Script kiddies are amateur hackers with limited technical knowledge. They use pre-made tools and scripts to launch attacks without understanding the underlying mechanisms.
  • Skills: Limited technical skills; rely on existing tools.
  • Activities: Carry out basic attacks using tools downloaded from the internet without understanding their functioning.


  • Intent: Hacktivists are politically or socially motivated. They use hacking to promote a specific agenda or cause.
  • Skills: Varied skills, ranging from basic to advanced.
  • Activities: Conduct cyber attacks, deface websites, or leak sensitive information to raise awareness for their cause.

Nation-State Hacker (Advanced Persistent Threat)

  • Intent: Sponsored by governments or nation-states to conduct espionage, sabotage, or gather intelligence.
  • Skills: APTs have highly advanced skills in cyber warfare and espionage.
  • Activities: Target critical infrastructure, conduct espionage, and engage in cyber warfare for geopolitical reasons.

Red Teamer

  • Intent: Part of a security team emulating attackers to test an organization’s defenses.
  • Skills: Possess advanced hacking skills and emulate real-world attackers.
  • Activities: Conduct penetration testing, attacking systems within legal boundaries to evaluate and improve defenses.

While a green hat hacker is typically a novice with a learning mindset, the other types exhibit varying intentions, skills, and activities, ranging from malicious intent to ethical hacking for improving security.
