A Beginner’s Guide to Malware Threats and How to Protect Your Systems

Cyber malware has become one of the most persistent and damaging types of cyberattack targeting organisations globally. Recent global security reports show that more than 500,000 new variants of malware are detected every day! 

As businesses hold valuable data and digital infrastructure, they are an obvious target for attackers. Ransomware attacks will lock up business-critical systems while stealthy spyware will collect sensitive information from unsuspecting victims. Malicious software is continually evolving in terms of its scale and sophistication.

This increased threat landscape requires all UAE employers to develop and maintain a solid mobile phone security protocol. A single successful malware attack can disrupt operations, compromise customer trust, and result in significant financial and reputational losses. As digital transformation accelerates, so does the urgency for organisations to understand how malware works and how it can be prevented.

What is Malware?

Malware, short for malicious software, refers to any program or code designed to harm, exploit, or gain unauthorised access to systems, networks, or data. Unlike legitimate software that serves a useful purpose, malware operates with the intent to disrupt operations, steal information, or provide attackers with control over targeted systems.

Malware exists in many forms, each designed to achieve different objectives. Some malware spreads rapidly across networks, while others remain hidden for long periods, silently collecting sensitive data.

Types of Malware

There are many types of malware that every business should be aware of. Although many new types of malware are created every day, the most common and most damaging types are listed below.

Virus

A virus attaches itself to a legitimate file or program and will spread through that file and program when it is executed. A virus can infect the entire computer and possibly all of the hard drives attached to that computer.

Worm

Worms automatically spread throughout the network with no user intervention. It takes advantage of vulnerabilities in computers, and it can rapidly infect a large number of systems, causing extensive network damage.

Trojan Horse

Trojans will appear as a legitimate application to the end user. When the end user downloads the application, it will then install itself onto the user’s computer and be able to create a backdoor for the attacker to access the computer and steal credentials or download additional malware.

Ransomware

This type of malware will completely encrypt the user’s files or entire system until the attacker receives the ransom payment. Ransomware is one of the worst types of malware for businesses because of the amount of downtime that occurs, and possible data loss.

Spyware

Spyware runs silently in the background while it collects very sensitive information from its users, including their login credentials, financial information, and the way they browse the internet, without the user’s knowledge.

Rootkits

Rootkits allow attackers to gain full administrative control of computer systems while remaining hidden. Because of their hidden nature, rootkits can be very difficult to find and remove.

Botnets

A botnet consists of many individual breaches of a user’s device that are all controlled remotely by the attacker. A botnet may be used to launch massive attacks, such as a Distributed Denial of Service (DDoS) attack.

Fileless Malware

Fileless Malware exists and operates in the computer’s memory instead of being stored on the hard drive. Fileless malware is more difficult for traditional cybersecurity solutions to detect. Businesses can gain insights into how Cloudlink combats this type of malware and read about how to combat fileless malware using modern detection tools by reading our complete guide.

Adware

Adware is a type of security threat that shows users pop-up advertisements while they browse the internet and may also track a user’s browsing activity. Although adware is usually seen as less of a threat than other types of security threats, adware can negatively impact a user’s computer’s speed and expose users to additional threats.

How Does Malware Attack Affect Systems?

Malware infections rarely occur by chance. Attackers use several common entry points to compromise systems and networks.

Phishing Attacks

Among the top delivery methods for malware are phishing emails. Phishing emails typically appear legitimate, convincing users to click on a bad link or open an infected file.

Software Vulnerabilities

Software vulnerabilities from outdated software or not properly patched software are an easy way for malware to take advantage of existing security flaws. Attackers look for systems that do not have updates.

USB Drives and Removable Media

Infected USB drives may introduce malware directly to systems, especially in environments where removable media such as USB drives are frequently used.

Malicious Links

By clicking on a compromised link embedded within an email or social media post, malware may automatically be downloaded to the user’s device.

Fake Apps/Software

Most users think they download actual software from a reputable source, but many times they download malware disguised as a legitimate application.

Malvertising

While using reputable sites, users may see malicious advertisements or ‘malvertising’ that may either direct them to a maliciously infected website or, once clicked, automatically download malware onto their devices.

How to Prevent Malware Attacks and Protect Data

To protect against malware and cyber attacks (and more), businesses should take a layered approach toward their security solutions. This “layered approach” consists of three separate but equally important layers: Technology, Policy, and User Awareness.

The Technology layer of a layered security approach means installing the latest technology (i.e., software) available and ensuring that they keep all known vulnerabilities closed through Patch Management or Systems Update programs. Access Management Systems (such as Multi-Factor Authentication) could strongly decrease the damage that occurs if a user’s credentials are compromised. Educating employees to identify Phishing or Social Engineering attacks can significantly reduce the potential of successful attacks occurring.

In addition, businesses should use the latest Advanced Security Solutions (such as Endpoint Protection, Network Monitoring, and Cloud Security Controls) in order to rapidly detect and respond to new Cyber Threats.
