• Strengthen cybersecurity frameworks.
• Implement multi-layered authentication for transactions.
• Regularly monitor network activity for suspicious behavior.

2. UIDAI Aadhaar Data Leak (2018)

A significant data breach exposed the personal details of over 1.1 billion Indian citizens registered with Aadhaar. Reports claimed that Aadhaar data, including names, addresses, and biometric details, were available for as little as ₹500.

Impact:

• Threat to national security and personal privacy.
• Increased risk of identity theft and financial fraud.
• Raised concerns over data protection laws in India.

Lessons Learned:

• Encrypt patient records and restrict access.
• Train healthcare staff on cybersecurity best practices.

4. AIIMS Ransomware Attack (2022)

The All India Institute of Medical Sciences (AIIMS) faced a massive ransomware attack that disrupted its digital services for several days. Hackers encrypted patient records and demanded a ransom in cryptocurrency.

Impact:

• Delayed medical services.
• Exposure of sensitive patient information.
• Costly recovery efforts.
