Use this script on your own VPS, home lab, or captured (authorized) pcap-derived logs. Never on systems you don’t own or have explicit permission to test.

We all know the drill. Downloading a pre-compiled tool and pointing it at a target is easy. But the moment that tool breaks, gets detected, or doesn’t fit the scenario, many users hit a wall.

Real skill isn't about having the biggest collection of malware or scanners. It's about understanding and being able to manipulate it yourself. Here’s a practical, 100% legal exercise to level up your Python skills while reinforcing good OpSec. Exercise: Build a Personal Log Parser (For YOUR systems only) The scenario: You have a server (or home router) generating thousands of SSH auth logs. You want to spot brute-force patterns without staring at a terminal for hours. elhacker.info

From 'Tool User' to 'Tool Maker': A Practical Guide to Log Analysis & OSINT Automation (Without Crossing the Line)

Once you understand this logic, you can adapt it to any CSV, JSON, or text dump from OSINT tools (like theHarvester, Sublist3r, or even your own Nmap XML outputs). Use this script on your own VPS, home

def parse_auth_log(logfile): failed_ips = [] try: with open(logfile, 'r') as f: for line in f: # Look for common failed password patterns if "Failed password" in line or "authentication failure" in line: # Extract IP address (assumes standard SSH log format) parts = line.split() for idx, part in enumerate(parts): if "from" in part and idx+1 < len(parts): ip = parts[idx+1] if len(ip.split('.')) == 4 or ':' in ip: # IPv4 or IPv6 failed_ips.append(ip) break except FileNotFoundError: print(f"[!] Log file not found: {logfile}") sys.exit(1)
