Sensitive data: this is information that should never be shared on the internet

Protecting sensitive data is an issue that concerns us all and is becoming increasingly important in our ever-more-connected world. Sharing certain information online, whether consciously or inadvertently, can have serious consequences for our lives. In this article, we remind you which sensitive data you should never share online, the risks associated with these practices, and offer advice on how to protect your personal information.

Sensitive data that should never be disclosed

Some information is particularly vulnerable and should never be shared online, not even with close friends or family, except through highly secure channels. Here are the main categories of data that should not be shared:

1. Passwords

We all use a variety of passwords, and they are the first line of defense for protecting our online accounts. These passwords allow us to access all types of accounts, such as your email, your social media profiles , a store you regularly shop at, or your bank's app.

Sharing your passwords, even with trusted individuals, carries risks and opens the door to cyberattacks. How can you be sure your password won't be leaked, that it will be used appropriately, and that it will be properly protected by a third party? A compromised password can expose a wealth of sensitive information.

2. Financial information

Besides passwords, you should never share your financial information online, even when someone asks for help, promises you a reward, or scares you with a supposed security risk. There's a good chance it's an extortion attempt. Therefore, you should keep all your financial information private, including credit card numbers, bank account details, and security codes.

This data is a prime target for cybercriminals, as it allows them to access your bank accounts and sometimes significant sums of money. Disclosing it, even accidentally, can lead to substantial financial losses.

3. Your identity documents

Your personal information must also remain private. Information contained in documents such as your identity card, passport, or driver's license can be used to steal your identity. This can have serious consequences, such as the creation of fake accounts in your name or the execution of illegal transactions.

4. Other sensitive information

In addition to this various data, there is also information that may seem harmless, but which can put you in danger if it falls into the wrong hands. This is the case with data such as your social security number , your date of birth, or your full address. This information can be combined to build a profile that allows access to other accounts or the perpetration of fraud. It can even be used to discover your address and commit a burglary!

5. Compromising photos or information

Many of us use social media daily, and this can pose risks, particularly regarding the data shared on these often poorly secured platforms. You might not think it's dangerous to share your vacation photos, intimate pictures, plane tickets, or other data online. But in some cases, this sharing can lead to privacy breaches, or even harassment or blackmail.

The best ways to protect your sensitive data online

Here's how to protect your sensitive information in a few simple steps:

1. The importance of choosing strong and unique passwords: You should choose complex passwords that include uppercase and lowercase letters, numbers, and special characters. Each password must be unique to the account it protects. To store your passwords more easily, you can use a password manager such as NordPass .
2. Enable two-factor authentication: This technique secures access to your accounts with an additional code. It is very convenient and strengthens password security.
3. Be vigilant against phishing attempts: Phishing attacks are among the most common online dangers, so you must remain vigilant. A cybercriminal may impersonate a trusted individual to try to steal your personal information. Always verify the legitimacy of these requests.
