Threat Type: Trojan

TrojanDownloader:MSIL/QuasarRAT.G!MTB is the name given to a specific Trojan horse malware by popular anti-malware software. Trojans are widely considered to be the worst possible form of malware infection due to their insidious nature.

Trojan horse malware is a variety of malware that masquerades as legitimate software in order to get installed on a user's computer or network. The name "Trojan horse" refers to the ancient Greek story of the Trojan horse, in which the Greeks used a large wooden horse to gain entry to the city of Troy. In much the same way, Trojan horse malware disguises itself as a trustworthy program in order to deceive users into downloading and installing it on their computers.

Trojan horses like TrojanDownloader:MSIL/QuasarRAT.G!MTB can be distrbuted via various means, including spam email, malicious websites, or bundled with other apps. Once installed, the malware can give its developers access to a user's personal information, such as banking and credit card info, login credentials, and browsing history. They also have the ability to use the malware to remotely commandeer the infected computer, and use it to launch further attacks, or to spread the Trojan to other devices on the network.

The impact of Trojan horse malware can be severe. In addition to giving cybercriminals access to highly sensitive information and allowing control over an infected device, it can also cause system instability, performance issues, and data loss.

To protect against TrojanDownloader:MSIL/QuasarRAT.G!MTB and other Trojan horses, it's important to be vigilant when opening email attachments or visiting unknown sites. Everyone should also keep their anti-virus and anti-malware software up to date and run regular scans to detect and deal with any potential threats. It's also smart to be aware of the signs of a Trojan horse infection, such as unexpected popups or changes to web browser defaults. If a user suspects that their computer is infected with Trojan horse malware, they should immediately run a full scan of their system and have the Trojan removed.

If your computer has an active infection with TrojanDownloader:MSIL/QuasarRAT.G!MTB, you should immediately use anti-malware software to remove it. We suggest that you follow the simple steps to eliminate the threat.

Protect Yourself From Trojans

Here are some steps you can take to prevent your computer from being infected by Trojan horses in the future:

  1. Keep your operating system and other apps up to date. Regularly check for software updates and install them as soon as they become available. This helps to fix vulnerabilities and prevent exploits.
  2. Use antimalware and/or antivirus software. A good antivirus program can detect and prevent Trojan horse infections. Make sure you also keep your antivirus software up to date and run regular scans.
  3. Be cautious when opening attachments or clicking on links. Do not open attachments or click on links from unknown or untrusted sources. Trojans can often be delivered via email attachments or infected links.
  4. Be careful with the software you do install. That includes browser extensions, games, utilities, and other apps.
  5. Use a firewall. A firewall can help to prevent unauthorized access to your computer and protect against network-based Trojan horse attacks. Today, these come bundled with MacOS and Windows. Your router may also provide NAT (Network Address Translation), which functions as a pretty good firewall.
  6. Educate yourself. Learn about the different types of Trojans and how to recognize them. This can help you to avoid becoming infected and take appropriate measures to protect your computer.
  7. Use strong passwords. We recommend everyone have a password manager (e.g. Apple Keychain, Bitwarden, 1Password, etc.) and commit to using it. Make sure to only use strong, unique passwords for your accounts and be cautious when giving out personal information online. Whatever you do, do not use the same password everywhere. Also make sure to use two-factor authentication (2FA) whenever possible.

By taking these steps and being mindful of the potential risks, you can help to protect your computer from being infected by Trojan horse malware.
