Could your tablet have a keylogger installed?

What is a keylogger?

A keylogger, or keystroke logger, is a piece of software that records each keystroke and letter that you type into a device. Whether you’re writing a blog post or social media update, typing a URL in an address bar, or adding credit card information while shopping online, a keylogger will track everything that you input.

There are legitimate and legal applications for keyloggers: Parents can monitor screen time for their children, companies can track productivity for employees and clients, and technical support can view a user’s inputs to troubleshoot problems.

But more often than not, they’re used by hackers and cyber-attackers to spy on victims. Because they can secretly record sensitive information, they’re often used to steal financial data, passwords, and identity information. These bad actors can also use data recorded by keyloggers to blackmail victims.

How to detect keylogging software on your tablet

Keyloggers hide on your tablet without you noticing that they’re running in the background. However, there are some telltale signs that can help you detect keyloggers.

• Your browser loads webpages slowly
• A lag in mouse movements, keystrokes, or other inputs
• Your cursor disappears (such as in a word processing app)

Because keyloggers are a form of spyware, you can use a reputable anti-malware program that scans your device and automatically removes spyware from your operating system. Microsoft Defender, built into Windows 11 and Office 365, can actively monitor your system for spyware such as mobile keystroke loggers. Browser extensions from trusted cybersecurity companies can also protect you from suspicious activity when you’re online.

In addition, you can take the time to examine the apps on your tablet and uninstall outdated or unfamiliar apps. Be sure to delete the data that comes with these apps. As a last resort, resetting your tablet to its factory settings is the most effective way to clear any possibility of spyware. Be sure to back up your personal data and apps beforehand so you can get back to where you were.

Stay on the defensive against cyberthreats

To avoid accidentally downloading malicious software, keep in mind the techniques to identify suspicious emails and phishing scams.

• Recognize the sender (from your company, IT department, or trusted addresses)
• Avoid downloading suspicious attachments or invoices
• Keep an eye out for special characters, misspellings, and unnecessarily long links
• Avoid entering personal information or passwords

Many suspicious emails will ask you to fulfill an invoice that you may not recognize or click on a link to reset your password. If you didn’t request to reset your password, or you don’t recognize the vendor or client, don’t interact with these emails and report them to your IT department.

Regardless, it’s important to regularly update your passwords to limit the chances of having your information compromised. Microsoft Edge features built-in password tools like Password Monitor, which alerts you if your passwords have been found in data breaches, or Password Generator, which can automatically create new and secure passwords that meet the requirements of the websites you’re logging into.

Whether you’re browsing on a tablet, a Surface laptop, or a mobile phone, keystroke loggers are a common threat that you can easily defend against. See more Privacy and Security tips to protect yourself online.
