• Data Breaches: Unauthorized access to sensitive personal or government data, leading to identity theft and financial losses.
  • Example: The 2023 AIIMS cyberattack exposed millions of patient records and severely disrupted hospital operations.
• Ransomware Attacks: Malicious software that encrypts critical data and demands payment for decryption keys.
  • Example: The global WannaCry ransomware attack in 2017 infected over 200,000 computers worldwide.
• Phishing Scams: Fraudulent communications designed to trick individuals into revealing sensitive credentials.
  • Example: A massive phishing campaign targeting Microsoft Office 365 in 2021 compromised numerous corporate accounts.
• Denial of Service (DoS/DDoS) Attacks: Flooding servers with malicious traffic to crash websites and online services.
  • Example: The 2016 Dyn DDoS attack temporarily brought down major global platforms like Twitter and Netflix.
• Spyware and Adware: Unauthorized software that secretly monitors user activity and steals private data.
  • Example: The Pegasus spyware controversy in 2021 targeted journalists and political figures globally.
• Insider Threats: Disgruntled or malicious employees misusing their authorized access to steal data or sabotage systems.
  • Example: The 2013 Edward Snowden leaks highlighted the immense risk posed by insider access.
• Supply Chain Attacks: Infiltrating third-party software vendors to compromise downstream target organizations.
  • Example: The 2020 SolarWinds hack compromised several US government systems through infected software updates.

Security Framework to Prevent Cyberattacks

• Network Security: Deploying robust firewalls, Intrusion Detection Systems (IDS), and Intrusion Prevention Systems (IPS) to block unauthorized network access.
• National Cybersecurity Policy: Implementing guidelines under India's National Cyber Security Policy to secure critical information infrastructure.
• CERT-In (Indian Computer Emergency Response Team): Utilizing CERT-In as the nodal agency for responding to cybersecurity incidents, issuing early warnings, and sharing threat intelligence.
• Critical Infrastructure Protection: Empowering the National Critical Information Infrastructure Protection Centre (NCIIPC) to secure vital sectors like power, banking, and defense.
• Regular Audits and Training: Conducting mandatory cyber audits for government departments and running continuous cybersecurity awareness programs for employees.
