    • Spear Phishing Email Example: An email impersonating a high-ranking official (Director of IIT Madras) sent from a suspicious Gmail account, demonstrating social engineering attacks.
    • Importance of verifying sender identity and email authenticity.
  • Phishing and Spear Phishing:
    • Phishing involves fraudulent attempts to obtain sensitive information.
    • Spear Phishing is a targeted form using background information to increase success.
  • Fake Website Example: A fraudulent link mimicking the State Bank of India’s login page used to steal credentials.
  • Ransomware Attacks:

  • Cyber attacks affect diverse sectors: manufacturing, healthcare, government.
  • Daily news reports indicate growing frequency and sophistication of cyber threats.
  • Digital transformation brings both benefits (economic growth) and risks (cyber threats).
  • The cyber world includes both “good” actors and “bad” actors exploiting vulnerabilities.
  • Statistics show 91% of organizations experience at least one cyber incident annually.
  • Cyber security is becoming a top priority for organizational leadership.

Methodology / Instructions Presented:

• Understand different types of cyber attacks:
  • Phishing and Spear Phishing (targeted social engineering).
  • Ransomware (data encryption and ransom demand).
  • Denial of Service attacks (briefly mentioned for future discussion).
• Stay informed about recent cyber incidents to understand evolving threats.
• Recognize the importance of keeping systems updated to reduce vulnerabilities.
