What is a Keylogger and How Can You Detect and Prevent it

What Is a Keylogger?

Keyloggers are software programs or hardware devices that track the activities (keys pressed) on a keyboard. Keyloggers are a form of spyware where users don’t know their actions are being tracked. Keyloggers can be used for a variety of purposes; hackers can use them to maliciously access your private information, while employers can use them to monitor employee activities. Some keyloggers can also capture your screen at random intervals; these are known as screen recorders. Keylogger software typically stores your keystrokes in a small file, which is either accessible later or automatically emailed to the person monitoring your actions.

Keylogger USBs and Viruses: How You Get Infected

Keyloggers can be broadly divided into two categories: hardware and software. There are a wide variety of more specific types that fall into each of the two categories, but here’s a quick rundown of each.

  • Hardware-enabled keyloggers:

Traditional keyloggers are installed at some point between a keyboard and the device itself. They’re often designed to look like ordinary computer components to avoid detection, often blending into a tangle of cords hanging behind a desk or workspace.

Keyboard overlays can be convincingly difficult to pull off, but when done right, they’re hard to spot. Much like an ATM skimmer, these fake keyboards fit perfectly into a real keyboard and relay keystrokes to a third-party snooper.

USB keyloggers, given the obvious difficulty in concealing their presence, are most often used for legitimate purposes, such as a workplace to monitor relayed information to protect trade secrets and other sensitive information.

  • Software-enabled keyloggers:

Phishing attacks are now one of the most common methods of delivering these devices. Since they can be transferred to a machine the same way as any other type of malware (by prompting a victim to open a web browser, download an attachment, or click on a link), one misstep of the user is enough to get this malicious payload. the door.

Trojan keyloggers are installed on users’ systems under false pretenses. Often times, they straddle the pigtails of an innocent-looking application to avoid arousing suspicion. So this pirated movie from a sketchy streaming site may have more twists and turns than originally intended.

How Hackers Install A Keylogger

A hacker uses a Trojan horse virus as a delivery tool to install a keylogger. But long before one is downloaded to your system, a hacker will use two different methods to get it into your computer. And both ways involve your participation.

The first method is to phish. Phishing involves faking an email from a legitimate business to find passwords and credit card numbers. Sometimes these emails contain attachments that download programs stealthily to your computer after you click on them.

For the second method, the hacker carries out preliminary research on his target in order to find a weakness in his online habits. Say a hacker finds out that the victim usually visits pornographic sites, the hacker can create an email with a fake coupon for an exclusive erotic website membership. Since this method targets a particular addiction of the victim, there is a high chance of success that they will download the fake attachment, unwittingly installing the keylogger.
