Keystroke Logging is an act to record whatever a user types on a computer or mobile keyboard. Keystroke Logging is done with the help of keyloggers. This is used to monitor your computer activities secretly when you normally use your devices. Keyloggers are generally used for legit purposes such as feedback for software development, however, some cybercriminals may steal your data for malicious purposes. For example, in 2017, the FBI arrested a student for placing keyloggers in the school computers for gaining access to the exams question papers.

What is Keystroke Logging?
The concept of Keystroke Logging:
Keystroke Logging: Keeping a record of every key pressed on your keyboard.
Keyloggers Tools: software or programs that are used for keystroke logging.
You can find the use of keyloggers in everything from Microsoft products to your employees’ workstations and laptops. In worse circumstances, hackers can upload keylogger malware on websites, software, applications, or even USB drivers.
How Do Keyloggers Work?
Keyloggers collect and transfer information to a third party - whether a criminal, police, or IT agency. A keylogger is basically a software program that leverages algorithms monitoring strokes through pattern recognition and many other ways.
The amount of data collected by the keylogger may vary. The basic form of keyloggers can only collect information that is typed into one website or application. However, the more advanced ones can record everything that you type, including what you copy and paste.
Several kinds of keyloggers – particularly the ones that target mobile devices - go much further and record information such as calls (call history and audio), messaging information, GPS tracking, screen recording, and even the capture camera.
Keyloggers can be both hardware-based and software-based. Hardware-based ones can just be placed between the computer’s port and the keyboard connector. The software can be downloaded unknowingly from a specific website where keyloggers are intentionally implanted.
Keylogger transfers the data to the attackers via email or log data uploaded to predetermined websites, databases, or FTP servers. If the keylogger gets bundled in a big attack, the attackers can simply log on to a computer to download the keystroke logging data remotely.
Signs of a Keystroke Logging Attack
The following are the signs of a keystroke logging attack:
- Keyloggers attack PCs (and Macs, Androids, and iPhones) in the same manner as the other malware.
- They are installed when you click on a file attachment that you were encouraged to open, mainly because you fell for a social engineering program or a smart phishing journey.
- You can receive attachments via e-mail, a text message, on social networks, or even by visiting a website that seems genuine but dangerous enough to implant keyloggers.
- Keyloggers rarely come solo. Similar to trojan, the keylogger can install other viruses on your system—for example, adware or spyware.
- Hardware keylogger infections occur when somebody gets access to an unlocked device. Say a crook somehow places a Keylogger plug on a PC’s USB keyboard port of a bank loan officer. This enables the attacker to obtain all sorts of useful data during the regular duties of the loan officer.
Can Keyloggers Infect Mobile Devices?
There is no evidence of hardware keyloggers infecting mobile devices till now. But the Android and iPhones are still prone to software keyloggers. There are claims that keylogging is not possible on mobile devices, as the screen of your mobile device is used as a virtual input keyboard. But, some keyloggers are designed to observe and record the buttons that the users click on their virtual keyboard.
When the keylogger infects the smartphone, it monitors rather than the keyboard action. Keyloggers can also record screenshots (emails, texts, login pages, etc.), camera photos, microphones, linked printers, and network traffic.
As for implanting keyloggers, anyone with weak access can become a victim of keystroke logging as attackers can easily implant keyloggers into your devices. In the case of laptops, tablets, and computers for PC or Mac, users might fall into the phishing or social engineering attack by clicking a suspicious attachment unknowingly.
How to Remove Keyloggers?
Security software like anti-keylogger software is specifically developed to scan software-based keyloggers by comparing files on your computer with a signature base of keylogger or common attributes of a keylogger. The use of an anti-keylogger can be more effective than an anti-virus because an anti-virus can detect a keylogger as a legit program.
Depending on the technique used by anti-keylogger software, it can detect a keylogger and report it to the security team. The use of a network monitor ensures a user is notified every time an application tries to connect to a network and the security team of the anti-keylogger blocks any keylogger activity detected.
Best Practices to Prevent Against Keystroke Logging
The first step towards security is to know how to spot a keylogger. For your devices to be keyloggers free, proactive prevention is important:
- Always read the terms and conditions of the services before accepting: Before signing up, you must know what you are giving consent to. Researching about the service you plan to install may be beneficial to you.
- Install internet safety software on all your devices: Malicious keyloggers try to make their way in software forms. Try to install good internet safety software on your devices.
- Make sure the latest threats are updated to your security programs: In order to properly detect threats, your security programs must be updated. Many security programs are updated automatically in order to carefully detect new threats or viruses.
- Don’t leave your mobile devices and PC unlocked: It might be all that a cybercriminal needs if he can steal your device or even take his hands on them for a moment. Keep on your devices locked to prevent the implantation of keyloggers.
- Keep all your device’s software updated: The latest security updates should be up-to-date to protect your operating system, software products, and web browsers.
Regardless of how you approach protection against keyloggers, the best defense is to install a good anti-logger software that protects against keyloggers malware. The use of a complete internet security solution with powerful keylogging features is an effective way to ensures security.
