A keylogger is a tool that captures keyboard activity from a computer system. While keyloggers can be used for legal purposes such as employee oversight or parental supervision techniques, it is illegal to install one without a user knowing. Hackers often leverage this form of spyware to intercept sensitive information such as email logins, PIN codes, and credit card numbers to ultimately commit identity theft or fraud.
Let’s dive into the different ways that keyloggers can sneak into your system, what suspicious activity to look out for, and the best measures to keep your organization protected.
What is a keylogger?
A keylogger is a type of software or hardware designed to monitor and record all keyboard strokes. Software keyloggers typically infiltrate systems through malicious links or files in phishing emails and infected website scripts. This collected information is then distributed to third parties through email, uploaded to websites, or added to a database.
Hardware keyloggers are small chips that are placed discreetly between the keyboard plug and port. Since this requires a cybercriminal to have physical computer access, software-based keyloggers are a more popular approach.
Ways to detect a keylogger
As keyloggers secretly hide in your system, proper detection can be challenging. However, knowing what to look for can go a long way. Some warning signs include unidentified apps, desktop icons, or processes in your task manager.
Another potential indicator is your computer’s overall performance. Be mindful of continuous disruptions such as lags, freezes, and crashes. Also, it’s important to take note of mouse and keystroke behavior. If you’re noticing inconsistencies between what you’re typing and the on-screen display, that may be a red flag.
How to protect yourself
According to the Verizon 2021 Data Breach Investigations Report, 61 percent of data breaches are linked to stolen credentials. To steer clear of this trap, avoid using the same password for multiple services and try to only use platforms that come with two-step authentication.
Other best practices include:
- Be cautious of clicking links or attachments from unfamiliar emails or websites.
- Make a habit of regularly updating your system and browsers with the latest security patches.
- Consider using a virtual keyboard, which enables you to input characters without touching the keys.
- Although keylogger identification isn’t guaranteed, antivirus software can offer an additional line of defense by routinely scanning for issues.
