It's just the beginning. 🔥 Real bug bounty impact comes from what you do after access This guide shows a clean, professional post-access workflow used in real engagements — focused on evidence, impact, and reporting . ⚠️ Ethical Use Disclaimer Only perform these actions on systems you own or are authorized to test (e.g., in-scope bug bounty targets or lab environments). 🎯 Objective Once you have SSH access, your goal is: Understand the environment Identify privilege boundaries Find misconfigurations Demonstrate real impact safely 🧭 Step 1 — Confirm Your Access 🖥️ Basic Context Run basic checks: whoami id hostname pwd 👉 This tells you: Your current user Your permissions Where you are 🧠 What You're Looking For Are you a low-privileged user? Is this a shared environment? Is this production or staging? 🔍 Step 2 — Quick System Enumeration Understand the system before touching anything. 🖥️ System Info uname -a cat /etc/os-release 🖥️ Running Processes ps aux 🖥️ Network ip a netstat -tulnp 🧠 Why This Matters Identify exposed services Spot internal-only services Find pivot opportunities 📂 Step 3 — Look for Sensitive Files 🖥️ High-Value Locations Check: /home/ /var/www/ /etc/ 🔎 Look for: .env files Backup files Config files API keys Database credentials Example DB_PASSWORD=SuperSecret123 👉 That's potential escalation or lateral movement 🔐 Step 4 — Check Sudo Permissions 🖥️ Command sudo -l 🖥️ Screenshot — Sudo Misconfig 🧠 What You Want NOPASSWD entries Ability to run commands as root 👉 This is one of the most common privilege escalation paths 🚀 Step 5 — Privilege Escalation Basics You are looking for ways to go: user → root Common Paths Sudo misconfig SUID binaries Weak permissions Cron jobs 🖥️ Find SUID Files find / -perm -4000 -type f 2>/dev/null 🖥️ Screenshot — Priv Esc Discovery 🧠 Goal 👉 Find a safe, demonstrable path to higher privileges 🔑 Step 6 — Credential Harvesting Once inside, credentials are everywhere. 🖥️ Where to Look Config files Browser data SSH keys Environment variables Example cat ~/.ssh/id_rsa 👉 May allow: Access to other systems Lateral movement 🌐 Step 7 — Internal Recon (Hidden Attack Surface) 🖥️ Check Internal Services netstat -tulnp 🖥️ Screenshot — Internal Services 🧠 Why This Is Powerful You may find: Internal dashboards Admin panels APIs not exposed publicly 👉 These often lead to critical bugs 🔄 Step 8 — Lateral Movement (Concept) If credentials are found: Try other users Try other systems Test access reuse 👉 This turns a low bug into: 💥 Full infrastructure compromise 💣 Real Impact Scenarios Here's what turns this into a high/critical report : 🔥 Example 1 — Privilege Escalation SSH access → low user Misconfigured sudo → root 👉 Full server control 🔥 Example 2 — Credential Reuse Found DB creds Access database Dump sensitive data 🔥 Example 3 — Internal Admin Panel Internal service exposed No auth required 👉 Account takeover / data access 📝 How to Report This Properly Title SSH Access Leads to Privilege Escalation and Internal Service Exposure Include Initial access method Step-by-step escalation Evidence (safe screenshots) Impact explanation Avoid ❌ Dumping sensitive data ❌ Over-exploiting ❌ Causing damage ⚡ Pro Tips (Operator Mindset) Move slowly and observe Take screenshots at every step Think: "What would an attacker do next?" Always aim for impact, not noise 🧠 Mental Model "Access is just the door. Impact is what's inside." 🏁 Final Takeaway SSH access alone is low value . But when combined with: Misconfigurations Credentials Internal services 👉 It becomes critical 👏 If This Helped Drop a clap Follow for real-world bug bounty techniques Support: 👉 https://buymeacoffee.com/ghostyjoe #bug-bounty #cybersecurity #linux #hacking #ssh Reporting a Problem Sometimes we have problems displaying some Medium posts.
