Keyloggers: Some Ways of Protection for Everyone

Keyloggers are one of the most well-known security threats . Είναι δύσκολο να εντοπιστούν, και η ζημιά που μπορούν να κάνουν δεν σταματάει στον υπολογιστή σας, αν για παράδειγμα το κακόβουλο λογισμικό σας έκλεψε τα στοιχεία της πιστωτικής σας κάρτας.Keyloggers

Keylogging malware is widely distributed, and is usually included in every variant of malware. Below we will try to see how you can protect yourself from one . To reiterate, there are no perfect defenses, but the steps we'll outline below will improve your system's security.

What are Keyloggers?

Before we see how we can stop a keylogger, we should see what it is, how it works and where it comes from.

Keylogger refers to a malicious program that records your keystrokes. Every word, every character and every button you tap on your keyboard is recorded.

At some point in the code, the keylogger sends the log to the attacker. The file may contain your bank connections, credit and debit card details, passwords, and anything else that you have entered on your computer.

Almost all keyloggers are accompanied by other malware. Previously malware keyloggers remained silent for as long as possible. This means that the files are not malicious, they just collect data as you continue to use your system.

However, this is not always the case. For example, the recently discovered MysteryBot targets Android devices with a banking Trojan, keylogger and . In general, a keylogger will appear as part of an exploit kit that gives the attacker control over various functions of your system.

But there is another form of keylogger. Card readers and skimmers who click on the PoS to copy your PIN. Along with all of the above, you should be careful about what USB you place on your computer and by whom.

But let's see how you can protect yourself:

Use Firewall

In most cases, the keylogger must send the data stored to the attacker via the Internet. But your Internet passes through a firewall (Firewall, for example, Windows Firewall). So there is a chance you can understand that something is wrong.
For more protection, you could also use a third-party firewall, although it is not recommended for your system's performance. Windows Firewall is a great tool, as long as you learn how to set it up.

Install Password Manager

Too many researchers recommend that you change your passwords frequently. It is practically very difficult, because we have to memorize dozens of passwords depending on the online services we use. Keyloggers of course do their job: they copy and store every piece of information you type. But what if you do not enter the passwords?

Most Password Managers use the auto-fill feature, The password is added to the password box without typing.

Unfortunately, only one not enough to protect you:

  • Some password managers do not copy – for your passwords. They use an auto-key feature to enter the password. So the keylogger will copy every data.
  • A well-designed keylogger periodically pulls screenshots, but also saves the content stored in the clipboard.

A good solution for all the above is the KeePass which uses TCATO (from Two-Channel Auto-Type Obfuscation). TCATO splits the password into two segments, sends them to the clipboard, and then merges them into the password box. However, let's say nothing is as safe as it claims, as it is theoretically possible to write a specialized monitoring application that specializes in recording this type of storage.

Update your system

Your system updates are necessary. Keyloggers and other malicious programs are looking for exploits on systems that have not been updated. However, security researchers are constantly finding new exploits that can be instantly updated. But it may not.

So as we mentioned from the beginning of the post nothing can be 100% safe. Frequent updates, however, significantly reduce the risk.

Search for additional security tools

The default security options for are impressive, but there are always specialized tools that add extra security.
For example Ghostpress, is a free anti-keylogger with a very small footprint in performance.

Change your codes

If you see that something is wrong, use a different computer and change all of your passwords.
