What is a Data Breach?

How Data Breaches Expose Sensitive or Confidential Information?

Data breaches compromise the integrity and confidentiality of sensitive information. They expose individuals and organisations to unauthorised entities who misuse data to extract money or commit financial fraud. For example, in 2024, 46% of data breaches involved compromising personally identifiable information, including tax identification numbers, email addresses, and home addresses. One report revealed that the average cost of a data breach was $4.88 million in 2024.

How Do Data Breaches Happen?

Data breaches occur through various vulnerabilities, exposing sensitive information to unauthorised access. Understanding these threats is vital to safeguarding organisations from potential risks. Some of the most common causes of data breaches include:

Hacking and Cyberattacks

Scammers exploit software, networks, or systems' vulnerabilities to gain unauthorised access to sensitive data. They use malware, ransomware, or denial-of-service (DoS) tactics to cause financial or moral harm to the user. 

They can also use advanced persistent threats (APTs) to infiltrate systems and steal data without being noticed for long periods.

Phishing Attacks

In phishing attacks, scammers trick employees into revealing sensitive information, like login credentials or financial data, through deceptive emails or messages.

For example, your employee may receive an email from the HR department urging them to update payroll details via a provided link. The link leads to a fake website mimicking the company's portal.

Insider Threats

An insider threat occurs when an employee, contractor, or business partner intentionally or unintentionally misuses their access to harm the company. For example, a software engineer in your tech firm steals and sells confidential data to a competitor. 

Since they already have system access, their actions go unnoticed until significant losses occur. Insider threats can be intentional or accidental but always pose serious risks.

Physical Theft

As the name implies, this breach occurs when someone breaks into your office and steals your company's official laptop, USB drive, or hard drive that holds sensitive data. If the stolen data is not encrypted, it can easily be accessed and misused against your company.

Unsecured Networks

Using an unsecured network allows scammers to intercept data or gain access to connected devices easily. For example, if you use public Wi-Fi to carry out any official or personal task, a scammer using the packet sniffing method can capture unencrypted data packets travelling over the network to extract your login credentials or credit card details.

Types of Data Breaches

Data breaches are classified into the following five types:

• Personal Data Breach: Scammers steal personal details like name, address, phone number, and Aadhaar number.
• Financial Data Breach: It involves the theft of banking details, credit card numbers, or digital payment credentials.
• Health Data Breach: This type of breach can result in the leak of sensitive medical records, insurance details, and patient history. It can also result in identity theft or discrimination based on medical conditions.
• Intellectual Property Breach: Hackers steal confidential business information, trade secrets, and research data.
• Credential Breach: This involves the compromise of usernames, passwords, and security codes of employees/administration.

Impact of Data Breaches

Data breaches have lasting impacts, highlighting the need for strong cybersecurity to protect businesses and individuals. Here are some of the most common and damaging consequences businesses may face:

Financial Losses

After a data breach, companies face hefty legal fees, regulatory penalties, and incident response costs. Past data indicates that, on average, companies incurred a loss of ₹176 million in the financial year 2021–22.

Moreover, if the breach has impacted customers, the company has to compensate them. Last but not least, a major amount is spent on improving security systems to prevent future breaches.

Reputation Damage

Studies reveal that around 65% of customers lose trust in a company when they come to know about a data breach. Not only that, but negative media coverage can make things worse, leading to lost customers, lower sales, and even business partnerships falling apart. Also, in such scenarios, competitors gain an edge.

Operational Disruption

Following a security breach, the company may be required to shut down its networks to contain the incident. This leads to operational downtime and a significant loss in productivity. Critical functions such as payment processing and customer support may come to a halt, while employees could face restricted access to essential files, disrupting the continuity of business operations.

In 2024, one report shows that the average time it took to investigate the breach, fix security gaps, and restore data was around 7.3 months. 

Legal Consequences

If sensitive customer or business information is exposed, your company may face fines and penalties for failing to protect data, especially under laws like the GDPR or India’s Data Protection Act.

Identity Theft and Fraud

As discussed, data breaches can lead to identity theft and fraud. In 2025, the FTC (Federal Trade Commission) received 1.4 million identity theft reports, with total losses estimated at $10.2 billion. 

How to Prevent Data Breaches?

Implementing these preventive measures majorly reduces the risk of data breaches, safeguarding sensitive information and maintaining trust in today's increasingly connected digital environment.

1. Strong Password Policies

Always have complex passwords that have uppercase and lowercase letters, numbers, and special characters. Make sure the password is hard to guess and that you are updating it regularly. 

2. Encryption and Access Controls

Encryption converts sensitive data into unreadable formats to prevent unauthorised access, even if the data is stolen. Use role-based access controls (RBAC) to ensure your employees can access only the data necessary for their roles. You must also use secure file-sharing protocols and encrypt communication channels.

3. Employee Training

Employees are often the weakest link in cybersecurity. Train them regularly on how they can recognise phishing emails and how to handle sensitive data. Simulated cyberattack drills help employees understand real threats and act accordingly.

4. Regular Security Audits

Conduct routine security audits to identify vulnerabilities in your system. You can conduct penetration testing, vulnerability assessments, and software updates. Also, keep an updated inventory of all digital assets, as it will help monitor security risks.

5. Multi-Factor Authentication (MFA)

MFA adds an extra layer of security by requiring users to verify their identity through multiple methods, such as passwords, biometrics, or one-time codes. Even if an attacker steals a password, they cannot access the system without the second authentication factor.

Examples of Data Breach 

India has witnessed several data breaches in recent years. Here are a few data breach examples:

Healthcare Sector Breach 

In 2022, one of the major healthcare institutions in India became a victim of a cyberattack. The incident resulted in the leakage of patient names, contact details, and medical histories of over 3.5 million patients. 

e-Commerce Platform Breach 

In 2023, a noted e-commerce platform in India experienced a data breach that affected approximately 20 million users. The leaked data included email addresses, hashed passwords, and transaction details.

Role of Cyber Insurance in Managing Data Breach Risks

Cyber insurance is crucial to shield your company from the financial risks associated with a data breach. Here are some common reasons:

Covers financial losses

Cyber insurance helps your business recover from financial losses caused by data breaches. It covers costs related to investigating the breach, compensating affected customers, and legal expenses. For example, if your company faces a ransomware attack, cyber insurance can cover the costs of restoring data, investigating the breach, and recovering operations.

Access to legal and technical expertise

Cyber insurance policies include access to legal advisors and technical experts who assist in managing the aftermath of a breach. These professionals help with forensic investigations, compliance with regulations, and public relations to minimise reputational damage.

Supports customer notification

Suppose you run an e-commerce platform, and it suffers a breach, exposing customer payment details. Cyber insurance can fund customer notifications and credit monitoring services. This coverage can help your business rebuild trust and prevent identity theft-related damages.

Conclusion

Considering the growing number of data breaches, you, as a business owner, must take a proactive approach to cybersecurity. You must implement strong security measures like encryption, multi-factor authentication, and regular security audits. 

You must also invest in comprehensive cyber insurance policies so that, even if a breach occurs, the right coverage helps you navigate financial losses, legal liabilities, and recovery costs.
