This article was created by the Bitdefender team for exclusive use on the Digital Radar blog

Spell checkers and text-verification features make life easier for anyone who writes and works online. However, certain features may send whatever you type to external servers in order to perform the correction. This is the context in which concern over so-called spelljacking arises.

So, in addition to reviewing your browser settings, having an antivirus software is an important measure to strengthen your device’s protection against a range of digital threats.

But what exactly is spelljacking, and how can you prevent confidential information from being exposed? Keep reading!

What Is Spelljacking?

Spelljacking is a term used to describe the risk of typed data being exposed when certain advanced spell-checking features send text to external servers for processing.

Depending on the page being used and the settings that are enabled, information entered into forms may be transmitted so that the service can offer spelling or grammar suggestions.

The problem becomes significant when the content involves confidential data, such as personal information, documents, credentials, or corporate data.

Spelljacking: What Information Can Be Exposed?

The risk depends on the service, the settings, and the field where the information is entered.

For this reason, it’s important to pay particular attention when typing:

● Personal data and documents
● Financial information
● Internal company data
● Usernames and other credentials
● Confidential client information

Password fields are normally handled in specific ways by browsers and websites, but that doesn’t eliminate the need for caution with extensions and additional features.

How to Protect Yourself from Spelljacking

The first step is to check which spell-checking features are enabled in your browser.

If there’s an enhanced checking option based on external services, consider whether you really need it.

It’s also worth reviewing your installed extensions and removing any you don’t use or that request excessive permissions.

In addition, keep your browsers and operating systems up to date, avoid installing extensions from unknown sources, and don’t enter sensitive information on pages you can’t trust.

In corporate environments, security policies can establish which browsers, extensions, and writing tools are permitted on the organization’s devices.

Ultimately, spelljacking shows that not every digital risk is directly related to malware.

Some privacy threats can arise from legitimate features that are configured improperly or used without due care.

That’s why reviewing permissions and settings should be part of your security habits. At the same time, using an antivirus software helps complement this strategy, offering protection against malware, malicious pages, and other threats that can compromise your computer.
