Malware attacks remain a core cybersecurity concern for organizations around the world. One of the common types of malware that scammers and hackers is the trojan horse, simply called a trojan. What exactly is trojan horse? What preventive steps can your business take to prevent such attacks? Here are some facts worth knowing.
Understanding trojan horse
A trojan horse is a malicious software, download or file, which looks legit, but can take control of a device, computer, or network. Hackers typically use trojans to steal information, launch ransomware attacks, spy on user activities, or often to cause harm to a network. Employees often fall prey to trojan horse attacks, because they are tricked into believing that the file or download is a genuine one.
Are trojans same as viruses?
While both viruses and trojans are used for similar purposes and intentions, both are not same. Yes, a virus is also a malware, and it can replicate itself, but a trojan cannot. In other words, trojans only work when someone runs or executes the file. Trojans can be used for causing backdoor attacks, as well.
How to prevent trojan attacks?
- Focus on internet security. Ensure that your employees know of phishing emails and malware attacks, and how they can be tricked by scammers into downloading trojans.
- If your business is not using an antimalware program, or internet security suite, as yet, it is time to invest in one.
- Ensure that all software, firmware, and operating systems are updated to the latest versions, as soon as these updates are made available by the parent company.
- Password protection is a must. Ask your employees to change default passwords immediately, with strong and unique passwords. Also, recommend a password management tool.
- Devices should be protected with firewalls. Ensure that all networked devices are scanned for trojan and malware files on a regular basis. Network scanning and penetration testing are important tools.
- Take backups regularly. In case a trojan attack does occur, backups will ensure that systems, networks, and devices can be restored immediately.
- Use network segmentation. This is more like a firebreak and can be really handy in reducing the impact of a trojan or malware attack.
- Ask your employees to watch out for email attachments. Emails remain one of the top sources of trojan files, and if an email sounds too good to be true, it probably is.
Preventing trojan attacks is about being proactive.
