Malware prevention for business: Dealing with trojans

Almost 30% of all cyberattacks can be traced to malware infections. Malware stands for malicious software, which is designed to cause one form of harm or the other. Trojan is also a type of malware, also called trojan horse. Trojan comes off as legitimate software or download, so the user is tricked into downloading and installing the same. Trojans are used by hackers and cybercriminals for various reasons, like deleting & copying data, causing ransomware attacks, interrupting networks, and often to modify information. In this post, we are discussing further on how small businesses can deal with trojans. 

Types of trojans

There are different kinds of trojan files that hackers may use. The most common is a trojan downloaded, which is designed to download and install other kinds of malware. There is also ransomware, which is used to encrypt files, and the hacker will demand a ransom to send a decryption key. Ransomware attacks often can cripple a company’s resources and networks, and many businesses do end up paying the ransom, although there is no assurance that the hacker has the key or will give the same. Another type is called a trojan dropper, which is hard to detect, while trojan banker is used for stealing card & online banking information. 

How to prevent trojan attacks?

The basic rules for preventing malware attacks also apply for trojans. For instance, you should avoid downloading files and attachments from unknown sources and suspicious websites. Employees are on the frontline of preventing malware attacks, and they must know about trojans and how hackers can target them using means like social engineering. Trojans often come from sources and emails that seem legitimate, but there is typically a catch involved. For instance, you may find a spelling mistake in what seems like a genuine site for download. Ask your employees to keep an eye on such details, and using antimalware and antispyware software can also come in handy for finding suspicious links, emails and attachments, which may contain trojans. 

Final word

Unfortunately, trojans remain a key concern for businesses, and employees end up making common yet silly mistakes. Do your homework and take the help of experienced cybersecurity services to take your cyber defenses to the next level. Test and check networks regularly, and ask your employees to use a barrier while using untrusted networks, such as firewalls. Using network segmentation and strong passwords is also recommended.
