Information leakage can happen in many ways, including hacking or theft, and if you’re not careful, your confidential information can easily be compromised.
What is data leakage?
Data leakage happens when people get information that they are not supposed to, and it can happen in different ways, either by accident or on purpose, and it would be better to be careful with your data, because it can get out, and someone can abuse it.
For example, imagine you have a credit card, and you use it to buy things online, your credit card number, expiration date, and security code are all sensitive information.

Another example is if you are a company, and you have employee records. These records can include social security numbers, addresses, and dates of birth, and if this information is disclosed, cybercriminals can use it to commit identity theft or fraud.
Data leakage is a serious problem because it can lead to loss of money, damage to reputation, etc. Therefore, it is important to be aware of the ways in which this can happen and take steps to prevent it.
How does data leakage happen?
There are several ways in which data leakage can happen, for example hacking, it happens when someone gains unauthorized access to a system or database, and they can do this by using special software or exploiting security holes.
Theft: This happens when someone steals data in a physical way, such as a laptop or hard drive. This can happen if you leave your device in a public place or someone breaks into your home or office.
Accidental Release: This occurs when data is accidentally released. For example, you may accidentally send an email to the wrong person or post something publicly that was meant to be private.
Company insiders: This occurs when someone who works for a company, such as an employee or contractor, intentionally releases data. They may do this for personal gain or damage to the company’s reputation.
Not following security measures: Data leaks can also happen when people do not follow proper security measures. For example, if an employee prints sensitive information and leaves it public, this is a form of data leak.
System Configuration Error: This occurs when an individual or the IT department of an organization fails to configure the system properly, which can lead to data exposure. For example, if a website’s database is not adequately protected, hackers can gain access to it.
There are many ways in which data leaks can occur. As you can see, it’s important to be vigilant about your data and take steps to protect it.
What are hackers looking for in the leaked data?
If you are an individual, the attacker’s first priority is to get your sensitive data during a data breach. This includes things like credit card numbers, social security numbers and more. Hackers can use this information to commit online fraud through phishing.
Hackers, unlike the above, will seek financial information such as bank account numbers and passwords, and they can use this to transfer money from your account or make unauthorized purchases.
How to prevent data leakage
When it comes to your sensitive data, you need to take every precaution to prevent it from falling into the wrong hands. So you should follow some basic precautions.
Initially, it is necessary to encrypt your files, as this makes it difficult for hackers to access your data, even if they manage to steal it. You should also consider using a Data Loss Prevention (DLP) system, as this software helps prevent leakage of sensitive information, and can do so by monitoring and blocking certain types of data from being transmitted.
If you are a business owner, train your employees on how to handle sensitive information. They need to know how to identify which information is sensitive and how to keep it safe.
Employees should know what to do if they think there is a data leak, because it would be better to have a data retention policy, which will determine how long the employee can keep certain confidential data and how to rotate it without risk.
Finally, to effectively protect your data from theft, you need to keep your software up to date, use strong passwords, use multi-factor authentication, use VPNs, be careful what you post online, watch for phishing scams, and finally your carefully monitor accounts from time to time.
