This blog discusses some of the most notable breaches in India, their impact, and the lessons to be learned to prevent further incidents.
Major Data Breaches in India
- Aadhaar Data Leak (2018)
Many times, a breach occurred in the storage of the biometric and demographic database of more than 1.3 billion Indians, Aadhaar. In 2018, it was reported that anyone could get Aadhaar-related details online for less than Rs. 500.

Lesson Learned:
End-to-end encryption must be a motto for companies in order to secure data from customers.
Regular security audits enable discovering and remediating vulnerabilities well ahead of hacking attempts.
Timely notice to affected users so that they can take action.
- Air India Data Breach 2021
Incident affecting 4.5 million customers-in an apparent cyber attack. Exposure of credit card data and personal details that were up to 10-years-old in the company's systems were the result. The attack profiled SITA, an international IT solutions provider for airlines, thereby having a broader influence.
Impact:
Travel details and passport information may be used for committing identity fraud.
Increased risk of financial fraud among airline customers.
This raised an alarm regarding the weaknesses of third-party service providers.
Lesson Learned:
Third-party service providers must comply with strict cybersecurity policies.
Airlines and travel companies should implement multi-factor authentication regarding their security.
Organizations should conduct thorough security vetting of all vendors and partners.

One of the leading fintech companies in India, Mobikwik, was compromised in a breach where a whopping 8.2 TB of user data, including KYC details, Aadhaar cards, and credit card information, was leaked. At first, the company denied any possibilities of breach, but cybersecurity experts have since confirmed that the data was available on dark web platforms.
Impact:
Exposure regarding financial details left the customers vulnerable to heavyweight dangers.
Government investigations ensue from this eminent breach, thus promising regulation tightening.
The strength of the fintech brand in data security was left quivering in the slack.
Lesson Learned:
Fintech must comply with regulatory security standards.
Proactive monitoring of data leaks will mitigate exposure damage before scale.
Secure storage of KYC data will be ensured.
- JustDial Data Breach (2019)
What actually happened is that JustDial, a well-known local search engine in India, leaked personal data of 100 million-plus users due to lack of security in a database. These included names, mobile numbers, addresses, and email IDs, causing a big stir regarding the safety of customer data.
Impact:
Increased risks to scam calls, phishing, and identity theft.
The affected users received spam marketing, fake schemes.
The data-handling practices of JustDial would be under scrutiny by regulatory authorities.
Lesson Learned:
Data needs to be secured by proper authentication and access controls.
Regular penetration testing can prevent loss of data through misconfigurations.
Sensitive and clear communication with users suffering from a breach would help.
How Indian Businesses Can Protect Themselves against Data Breach
Considering the increase in the number of cyber threats, the only refuge available to Indian businesses is going under some very stringent measures of security. Among the most effective are:
- Strong Encryption
Encrypting sensitive data ensures that even if hackers gain access, the data cannot be used without the decryption key.
- Regular Security Audits and Penetration Testing
Regular assessments are important to seal known vulnerabilities before the attackers can exploit them.
- Multi-Factor Authentication (MFA)
MFA adds an extra level beyond a password which reduces risk of unauthorized access.
- Employee Training and Awareness
Employee breaches are the leading cause of breaches. Employees receive cybersecurity training in an effort to avoid phishing and other social engineering attacks.
