Discovering SQL Injection Vulnerabilities in Web Applications Discovering SQL Injection Vulnerabilities in Web Applications: A Complete Guide Keywords: SQL Injection, Web App Security, SQLMap, Penetration Testing, Cybersecurity, Database Exploits, OWASP Introduction Among the most dangerous and commonly exploited web application vulnerabilities is SQL Injection (SQLi) . It allows attackers to interfere with database queries by injecting malicious SQL code, potentially gaining unauthorized access to sensitive data. This guide will walk you through the process of identifying and testing for SQLi, along with prevention strategies to secure your applications. What is SQL Injection? SQL Injection is a vulnerability that occurs when an application fails to properly validate and sanitize user inputs before using them in SQL queries. This allows attackers to manipulate the SQL logic and execute unauthorized queries. Basic vulnerable query example: S...

Top 20 Future Technology Trends by 2030 | humanotesfacts Top 20 Future Technology Trends by 2030 Imagine waking up in a world where your AI assistant knows exactly what you need before you say a word. Your doctor is an algorithm, your office is in the metaverse, and your coworker is a humanoid robot. It sounds like science fiction—but it's not anymore. 1. Artificial General Intelligence (AGI) AGI refers to machines that can understand, learn, and reason like a human. Unlike current AI models that are task-specific, AGI will adapt and perform across domains. We may see early forms emerge before 2030, changing every industry as we know it. 2. Humanoid Robots Companies like Tesla, Figure AI, and Nvidia are building humanoid robots that can walk, work, and interact with humans. These robots are teachable, agile, and will soon assist in homes, factories, and hospitals. 3. AI Agents and Autonomous Workforces AI agents like AutoGPT and D...

  How to Build a Malware Detector Using Python? Introduction Malware attacks are increasing rapidly, making detection tools essential. In this article, we’ll build a simple Python tool to detect suspicious executable files (PE format) — a foundation for more advanced security projects. Tools Used pefile  library: To analyze Windows PE files. os  module: For file system operations. The Code python Copy Download import pefile import os def scan_file ( file_path ) : try : pe = pefile . PE ( file_path ) print ( f"[+] Analyzing: { file_path } " ) suspicious_features = [ ] if pe . is_exe ( ) : # Is it an executable? suspicious_features . append ( "EXE file" ) if pe . is_dll ( ) : # Is it a DLL? suspicious_features . append ( "DLL file" ) if len ( pe . sections ) > 5 : # Unusual section count suspiciou...

  Ever wondered "Who's on my WiFi?" Today, we'll build a tool that answers exactly that! Using the powerful  Scapy  library, we'll create a network scanner that reveals all connected devices. Perfect for home network security monitoring. Why This Tool is Useful: Detect unknown devices (intruders!). Monitor network activity. Foundation for advanced security tools. The Code (With Explanation): # 1. Import libraries from scapy.all import ARP, Ether, srp # 2. Define network range (Change 192.168.1.1/24 to yours!) target_ip = "192.168.1.1/24" # 3. Create ARP packet arp = ARP(pdst=target_ip) ether = Ether(dst="ff:ff:ff:ff:ff:ff") packet = ether/arp # Combine packets # 4. Send packet & capture responses (timeout=3 sec) result = srp(packet, timeout=3, verbose=0)[0] # 5. Print results print("Discovered Devices:") for sent, received in result: print(f"IP: {received.psrc} - MAC: {received.hwsrc}") How to Run: Install li...
