Your Data or Password Has Been Leaked—Here’s What to Do Immediately
Data breaches are becoming increasingly frequent, putting your email accounts, passwords, and banking information at serious risk. While receiving a breach notification can be alarming, panic is not the solution. Instead, taking swift and decisive action can safeguard your online accounts, financial details, and personal data from cybercriminals. With the right security measures, you can significantly reduce the chances of falling victim to identity theft or financial fraud.
Understanding the Growing Threat of Data Breaches in India
Data breaches have become a routine part of digital life. Many people receive an email titled “Notice of Data Breach” informing them that some of their information has been compromised. These messages often downplay the severity, stating that the situation is under control and no evidence of misuse has been found. Because there is no immediate visible damage, most recipients simply ignore the warning. However, treating cybersecurity lightly can have severe consequences—especially in India, where digital payments, UPI, net banking, and e-wallets are used daily. If your email or password is leaked, your bank accounts and other critical services could be next. Instead of worrying, you need to act. Here is a step-by-step guide to protecting yourself.
Major Data Breaches in India (2025–2026)
The period from 2025 to early 2026 witnessed a sharp rise in data breaches and cyberattacks across India. Understanding these incidents highlights the urgency of securing your digital life.
Retail Chain Data Leak (October 2025)
A nationwide grocery retail chain suffered a massive attack, exposing the personal data of 600,000 customers and 1,000 employees. The leaked information included sensitive details such as Aadhaar card numbers and banking information.
Tata Technologies
In January 2025, the company reported a ransomware attack that impacted several of its IT assets, disrupting operations and compromising data.
Fintech and Payment Systems
In January 2025, unauthorized access was discovered in the production database and source code of a major Indian multinational payment system. The stolen data was later listed for sale on the dark web.
Angel One
In February 2025, the company reported tampering with its Amazon Web Services (AWS) resources, raising concerns about cloud security.
Niva Bupa
In February 2025, this health insurance company launched an investigation into claims of customer data leakage, underscoring vulnerabilities in the healthcare sector.
Cloud Storage Exposure
In January 2025, more than 22 terabytes of sensitive data from multiple Indian companies were exposed, primarily due to misconfigured S3 buckets.
Early 2026 Trends and Reports
According to a February 2026 report, Indian organizations faced an average of 3,195 cyberattacks per week. The most targeted sectors included education (7,684 attacks per week), government institutions (4,912 attacks), and professional services.
Raymond
In late February 2025, the company reported a security incident that forced it to isolate certain IT assets to prevent further damage.
Key Statistics (2025–2026)
- Total attacks: India recorded over 265 million cyberattacks during 2025.
- CERT-In’s role: The Indian Computer Emergency Response Team handled approximately 2.94 million cyber incidents in 2025.
- Primary threats: Trojans (43%) and infectors (34%) emerged as the most significant dangers, with Maharashtra and Delhi being the most affected states.
Step 1: Secure Your Email Account Immediately
Your email account acts as the master key to all your online services. If a hacker gains access to your personal or work email, they can easily reset passwords for your banking apps, social media, cloud storage, and more—even without knowing your original passwords. All they need is to click “Forgot Password.”
What to Do
If you suspect your email password has been leaked, change it right away. Create a long, unique password that you have never used before. Avoid common words or predictable patterns.
Boost Security with Two-Factor Authentication
Enable two-factor authentication (2FA) on your email account. The safest methods include using an authenticator app or a hardware security key rather than SMS-based OTPs.
Avoid SMS-Based OTPs
In India, receiving OTPs via SMS is the most common method, but it is also the least secure. Hackers can use SIM-swapping techniques to take control of your phone number. Authenticator apps generate codes directly on your device, eliminating this risk.
Check Login Activity
Go into your email settings and review recent login activity. Look for any unfamiliar devices or locations. If you spot something suspicious, sign out of all active sessions immediately.
Step 2: Change Leaked and Repeated Passwords
Beyond your email, update passwords for any accounts directly affected by the breach. Reusing the same password across multiple sites is one of the biggest mistakes you can make. Attackers automatically test leaked email and password combinations on hundreds of popular websites.
How to Create a Strong Password
Your password should be long and random—at least 14 characters. Alternatively, consider using a passphrase style, such as a series of unrelated words combined with numbers and symbols.
Use a Password Manager
Remembering dozens of complex passwords is nearly impossible. A password manager—like iCloud Keychain on iOS or Google Password Manager on Android—can securely store and autofill your credentials.
Adopt Passkeys
Whenever a service offers passkeys, enable them. Passkeys eliminate the need for traditional passwords entirely, using fingerprint or Face ID for authentication. They cannot be hacked or phished.
Step 3: Enable Two-Factor Authentication Everywhere Possible
Two-factor authentication adds an extra layer of security to your accounts. In addition to your password, you will need a temporary code or biometric scan to log in. Activate 2FA on any account that contains personal data or banking details. When setting it up, save the recovery codes provided in a secure location. If you lose your phone or authenticator app, these codes are your only way to regain access.
Step 4: Monitor for Suspicious Activity
After updating your security settings, check whether any unauthorized access has already occurred. Carefully review recent login history and transaction records, especially for UPI and credit card statements. Also, examine your email settings for any unknown forwarding rules that may have been added without your knowledge. If you notice any unauthorized activity, contact the relevant service provider or bank immediately.
Step 5: Remove Unnecessary Apps and Device Access
Over time, you may have granted access to various third-party apps, browser extensions, and old devices. These often become the weakest link during a breach. Go into your account settings and revoke access for any connected apps or devices you no longer use. This simple step can prevent attackers from exploiting forgotten entry points.
Step 6: Stay Vigilant for the Long Term
Even after securing everything, ongoing vigilance is essential. Some attackers do not use stolen data immediately; they wait months for you to let your guard down. Sign up for breach alerts through a password manager or identity monitoring service. While a data breach can be unsettling, it does not have to lead to identity theft or financial loss. By taking concrete steps—securing your email, creating strong passwords, and enabling extra security layers like 2FA—you can be fully prepared for the next breach. And make no mistake: another data breach is almost certain to happen.
