Do you remember every key you pressed on your laptop today? Every word you typed in an email? Every password you punched in? Every digit you entered for your credit card?

For you and me, recalling all that information is next to impossible. But not for a Keylogger.

Keyloggers have practical applications, but too often they’re deployed maliciously.

So what exactly is a Keylogger?

Keylogger is short for Keystroke logger, a surveillance tool that records every keystroke made on a device – without the user knowing.

Keyloggers can be hardware or software, and they’re used for things like parental controls or employee monitoring…

But they’re also used for identity theft, fraud, and spying.

A Keylogger isn’t a virus, but sometimes it’s part of a virus or malware designed to steal passwords and other private data.

Keyloggers are first installed on a target device, then they start recording keystrokes and capturing data. They then transmit the data to the hacker or store it until it’s retrieved.

Hardware Keyloggers have to be physically connected to a device, usually via a USB or PS/2 port. They’re easy to install and difficult to detect with software, but they’re fairly easy to detect by physically inspecting the device. Plus they have to be physically accessed by the attacker to download the data.

Software Keyloggers are installed remotely through malicious downloads, phishing email attachments, or system hacks. They send data back to the hacker over the internet. Good anti-spyware programs can spot and eliminate them, but attackers are always inventing new ways to evade security.

Once a Keylogger is installed, it captures every keystroke the user makes – that means passwords, emails, instant messages, credit cards and bank information are all at risk of being stolen.

Some software keyloggers even capture screenshots, clipboard data, and browser history.

And, keyloggers can infect any device – laptops, desktops, or mobile.

It’s tough to spot a sophisticated Keylogger, but here are some key things to watch out for…

Unusual activity – pay attention to sluggish performance, unresponsive programs, unexpected crashes, surges in disk activity or outgoing network traffic when you’re not using the internet.
Check for suspicious processes with Task Manager on Windows or Activity Monitor on a Mac.

Unknown devices – hardware keyloggers will likely be connected between your keyboard cable and computer.

Fortunately, there are a lot of ways to keep your data safe from Keyloggers…

Use anti-virus and anti-keylogger software

  • Make sure your OS is up to date with the latest security
  • Download only from trusted sources and beware of phishing attempts
  • Use a firewall
  • Use strong, unique passwords
  • Enable multi-factor authentication
  • Monitor your attack surface for vulnerabilities – that means hardware, s-oftware, network, even other people using your device
  • Beware of public computers
  • And use managed devices for work

Cloud identity management systems like the JumpCloud Directory Platform provide multiple strategies and capabilities to streamline the security process across organizations -- and put a stop to malicious keyloggers.
