Data Leak Checker

This section explains how to check if your user account data can be accessed publicly.

About Data Leak Checker

Data Leak Checker on Kaspersky Basic and Kaspersky Standard plans lets you manually check only the My Kaspersky account. Automatic checks for your My Kaspersky account and other accounts are available only for Kaspersky Plus and Kaspersky Premium plans.

Most users create accounts on various websites for work, shopping, and communication purposes. There is always the risk that attackers could hack the site and gain access to user data. If you use the same email address and password for different sites, it is more likely that your data will be leaked.

With the Kaspersky application, you can check your user accounts for potential leaks. If the check reveals that your data may be publicly accessible, the application will notify you about it and display a list of sites from which a data leak could have occurred, the date of possible leakage, and the category of data that may be publicly accessible.

The Kaspersky application also checks your accounts for data leaks to Darknet. If a leak is found, the application warns you about it.

When checking user accounts, Kaspersky does not retrieve data in plaintext form, and uses it only for the specified check without storing it. On detecting a leak, the Kaspersky application does not gain access to the user data itself, but only provides information about categories of data that may be publicly accessible.

The Kaspersky application can notify you of a possible leak of the following categories of data:

• Personal data: for example, passport data, biometric data, data about age.
• Banking data: for example, numbers of credit cards and bank accounts, information about funds available on credit cards and bank accounts.
• Activity history: for example, authentication tokens, password history.

By default, the Kaspersky application tries to check your user accounts when you are authorized on a particular website. During authorization, your email address used to sign in to the website is encrypted and forwarded to the KSN cloud. If the check reveals that your data may be publicly accessible, you will receive an appropriate notification. You can disable Data Leak Checker.

You can add up to 50 accounts for automatic checking. Lists of accounts in the Kaspersky application are not synchronized between devices. Added accounts are checked once a day.

Adding accounts to the list for automatic checking may be unavailable in your region.

The Kaspersky application periodically checks the email address linked to your My Kaspersky account. The first such check is performed 48 hours after installation of Kaspersky. Further checks are made every 24 hours.

Data Leak Checker for My Kaspersky account does not work if the Kaspersky application is not connected to My Kaspersky or the My Kaspersky account password is not entered in the application.

Clicking a data category link will provide recommendations on how to minimize the consequences of a possible leak of this data.

   The Kaspersky application lets you check for possible leaks of not only your own data, but from other user accounts that belong to your friends and family, for example.
