Introduction to Social Engineering Social engineering is the part of cybersecurity course and  art of manipulating people into divulging confidential information or performing actions that compromise security. It exploits human psychology rather than technical vulnerabilities. Why It Works - 98% of cyberattacks involve social engineering (IBM) - Humans are the weakest link in security - Low-cost, high-reward for attackers Types of Social Engineering Attacks in cybersecurity  1. Phishing (Most Common) - Deceptive emails/messages pretending to be legitimate - Goals: Steal credentials, spread malware, financial fraud Types:   - Email phishing (Fake invoices, "urgent" requests)   - Spear phishing (Targeted at individuals)   - Whaling (Targets executives)   - Smishing (SMS phishing)   - Vishing (Voice call phishing) 2. Pretexting - Creating a fabricated scenario to obtain information - Example: "IT support" calling to "verify your password" 3. Baiting ...

Introduction Sniffing and session hijacking are critical network attacks where an attacker intercepts and manipulates network traffic to steal sensitive data or take over authenticated sessions. This guide covers techniques, tools, and defenses. 1. Network Sniffing What is Sniffing ? - Capturing and analyzing network traffic. - Used for passive reconnaissance (e.g., stealing passwords, cookies). - Works on unencrypted (HTTP, FTP, Telnet) and weakly encrypted protocols. Types of Sniffing 1. Passive Sniffing      - Works on hubs (broadcast traffic).      - Attacker silently captures packets.   2. Active Sniffing       - Works on switched networks (requires ARP spoofing).      - Techniques: ARP Poisoning, MAC Flooding, DNS Spoofing.   Sniffing Tools | Tool | Purpose | |------|---------| |   Wireshark  | GUI-based packet analyzer | |    Tcpdump  | Command-line packet ...

Introduction to Malware Malware making is the part of cybersecurity course. Malware (Malicious Software) is any program designed to harm, exploit, or infiltrate a system without the user's consent. It includes viruses, worms, trojans, ransomware, spyware, and more. Types of Malware 1. Viruses - Attaches itself to clean files and spreads when executed. - Example: ILOVEYOU, Melissa. 2. Worms - Self-replicating malware that spreads over networks. - Example: WannaCry, Conficker. 3. Trojans - Disguised as legitimate software but performs malicious actions. - Example: Zeus , Emotet. 4. Ransomware - Encrypts files and demands payment for decryption. - Example: REvil , LockBit. 5. Spyware - Secretly monitors user activity (keyloggers, screen capture). - Example: DarkComet , FinFisher. 6. Rootkits - Gains privileged access and hides malicious processes. - Example: Stuxnet , TDL4. 7. Adware - Displays unwanted ads and collects user data. - Example: Fireball , Superfish. 8.
