A curated, zero-fluff reference guide for penetration testers, CTF competitors, and cybersecurity students.
When you are in the middle of a time-constrained engagement, lab, or certification exam (such as OSCP, eJPT, or Security+), parsing through lengthy documentation breaks your momentum. This repository provides exact commands, syntax examples, and core methodologies at a glance.
The cheatsheets are categorized into core cybersecurity domains for rapid navigation.
- Nmap Scanning - Host discovery, aggressive scanning, and NSE scripts.
- Common Ports & Protocols - Target services and their common exploitation vectors.
- Wireshark Filters - Isolating malware beacons, cleartext credentials, and recon traffic.
- Linux Commands & PrivEsc - SUID binaries, Cron jobs, and system enumeration.
- Windows AD Basics - Active Directory enumeration, LotL tactics, and PowerShell cmdlets.
- iOS Admin & Security - MDM profiles, libimobiledevice, and jailbreak runtime analysis.
- Hashcat & Password Cracking - Attack modes, masks, and hash identification.
- Encoding vs. Encryption - Base64, URL encoding, symmetric/asymmetric encryption, and hashing principles.
Keep a local copy on your attack machine (Kali Linux, Parrot OS, Commando VM) to ensure you have access to your notes even in offline exam environments.
git clone https://github.com/Wecncode/Cybersecurity-Cheatsheets.git
cd Cybersecurity-Cheatsheets
Use terminal utilities like grep to quickly find syntax on the fly:
Example: Quickly finding the Nmap syntax for a UDP scan
grep -i "UDP" Networking-Fundamentals/Network-Ports-Protocols.md
Simply bookmark this repository and use GitHub's native Markdown rendering to read the tables and copy commands directly to your clipboard.
Action-Oriented: We prioritize commands over theory. If it doesn't help you type a command or understand a vulnerability path, it's not here.
CTF & Exam Focused: Tailored for the specific challenges found on platforms like HackTheBox, TryHackMe, and OffSec labs.
Living Document: Constantly updated with modern LotL techniques and new tool syntax.
Cybersecurity thrives on knowledge sharing. If you have a favorite command, a new tool, or an exploit path that isn't documented here, we welcome your contributions!
