When most people hear the phrase “things you didn’t know about malware,” they immediately think of viruses. However, viruses are just one type of malware, and there are many others that can cause just as much, if not more, damage.

Malware is an umbrella term that includes various types of malicious software, each with a different purpose. Trojans disguise themselves as legitimate programs but secretly steal data or provide hackers with access to your system. Worms spread across networks without any user interaction, making them incredibly dangerous for businesses. Ransomware locks users out of their own files until they pay a ransom, and spyware silently monitors activities to collect sensitive information like passwords and financial details.

Understanding these things you didn’t know about malware is crucial because different types require different prevention and removal strategies. Simply installing an antivirus program may not be enough, strong cybersecurity practices are needed to defend against these evolving threats.

The First Malware Dates Back to the 1970s

Many people assume malware is a modern day problem, but its origins go back over 50 years. The first known malware, called Creeper, was created in 1971 as an experimental program. It was designed by Bob Thomas, an engineer working on early computer networks. Creeper didn’t cause harm but displayed a simple message: “I’m the Creeper, catch me if you can!”

Although Creeper was harmless, it paved the way for future malicious software. In response, another program called Reaper was developed to track down and remove Creeper, making it the world’s first antivirus software.

As technology advanced, so did malware. By the 1980s and 1990s, viruses like the Morris Worm and ILOVEYOU were causing widespread disruption, infecting thousands of computers worldwide. Today’s malware is far more sophisticated, targeting everything from personal devices to large scale businesses. This evolution highlights the ongoing need for strong cybersecurity measures.

Malware Can Infiltrate Smartphones and IoT Devices

Many people assume malware only affects computers, but one of the things you didn’t know about malware is that smartphones and Internet of Things (IoT) devices are just as vulnerable. Hackers target mobile phones through malicious apps, fake downloads, and phishing messages, gaining access to sensitive data such as banking details, passwords, and personal conversations.

IoT devices, including smart TVs, security cameras, and even household appliances, are increasingly becoming a target. Many of these devices lack built in security, making them easy entry points for cybercriminals. Once infected, malware can turn smart devices into botnets, allowing hackers to launch large scale attacks without the owner even knowing.

One example is Mirai, a malware strain that took control of thousands of IoT devices, using them to carry out distributed denial of service (DDoS) attacks. Among the things you didn’t know about malware is that the rise in connected technology means stronger cybersecurity measures are needed, not just for computers, but for all internet connected devices. Regular updates and strong passwords can help reduce the risk. Building a strong security mindset within your business is crucial.

Cybercriminals Use Malware for Financial Gain

While some early malware was created for experimentation or mischief, today’s cybercriminals use malware for one main reason, money. From stealing financial details to extorting businesses, malware has become a highly profitable industry.

Ransomware is one of the most damaging types of financially motivated malware. Hackers encrypt victims’ files and demand payment, often in cryptocurrency, to restore access. High profile ransomware attacks have crippled businesses, hospitals, and even local governments, costing millions in damages.

Another common tactic is banking malware, which secretly records keystrokes or intercepts login details to gain access to bank accounts. Ad fraud malware also generates revenue by forcing infected devices to visit fake websites, increasing ad revenue for cybercriminals.

Many of these operations are highly organised, with criminals selling malware kits on the dark web, allowing even those with minimal technical knowledge to launch attacks. Businesses and individuals must stay vigilant, using security software and safe browsing practices to protect their finances.

Some Malware Operates Without Immediate Detection

Not all malware causes instant chaos, some operate in the background for weeks, months, or even years without being noticed. This type of malware is designed to stay hidden while silently collecting information, spreading across networks, or waiting for the perfect moment to strike.

Rootkits are one example of stealthy malware. They embed themselves deep within a system, allowing hackers to gain remote access and control without triggering security alarms. Keyloggers are another hidden threat, recording everything a user types, passwords, messages, and financial details without their knowledge.

Some Advanced Persistent Threats (APTs) specifically target businesses and government organisations, remaining undetected while siphoning sensitive data over long periods. These threats are often used for corporate espionage or political cyber warfare.

Because this type of malware is difficult to detect, regular security scans, multi factor authentication, and monitoring for unusual activity are essential for both businesses and individuals to stay protected.

Email Is a Common Malware Delivery Method

Phishing email, demonstrating things you didn’t know about malware being delivered through email scams.

One of the easiest ways for cybercriminals to spread malware is through email. Every day, millions of phishing emails are sent to unsuspecting users, tricking them into clicking malicious links or downloading infected attachments.

These emails often appear to come from trusted sources, such as banks, delivery companies, or even colleagues. They may urge the recipient to take immediate action, like updating account details or opening an invoice. Once the link is clicked or the attachment is opened, malware is installed on the device, giving hackers access to sensitive information or control over the system.

A well known example is the Emotet malware, which spread globally through phishing emails disguised as legitimate documents. Businesses and individuals can reduce their risk by using email filters, avoiding unexpected attachments, and verifying sender addresses before clicking links. Cybercriminals rely on human error, so awareness is one of the best defences against email based malware attacks.

Malware Can Exploit Software Vulnerabilities

Many malware attacks don’t require users to click on a suspicious link or download an attachment, outdated software can be enough to let hackers in. Cyber Criminals often exploit weaknesses, known as vulnerabilities, in operating systems, applications, or plugins to install malware without any user action.

One of the most infamous examples is the WannaCry ransomware attack in 2017, which spread globally by targeting an unpatched vulnerability in Windows systems. Thousands of businesses, hospitals, and government agencies were affected, with many forced to pay ransoms to regain access to their files.

Regularly updating software is one of the simplest yet most effective ways to prevent malware infections. Security patches are released to fix known vulnerabilities, so delaying updates leaves systems exposed. Businesses should also apply patch management policies to ensure all devices stay protected, as even a single outdated computer on a network can put the entire organisation at risk.

The Rise of Malware as a Service (MaaS)

Cybercrime is no longer limited to highly skilled hackers, Malware as a Service (MaaS) has made it accessible to anyone willing to pay. Similar to legitimate software subscription models, MaaS allows criminals to purchase or rent malware tools on the dark web, making it easier than ever to launch cyber attacks.

MaaS providers offer ready made hacking kits, complete with user guides and customer support. These services include ransomware, botnets, spyware, and phishing tools, enabling even non technical criminals to carry out sophisticated attacks. Some MaaS operators even run “profit sharing” schemes, where they take a percentage of the money extorted from victims.

The rise of MaaS has led to a surge in cyberattacks, with ransomware as a service (RaaS) being one of the most damaging. Businesses and individuals must stay vigilant, as cybercriminals no longer need expert knowledge to distribute dangerous malware. Investing in strong cybersecurity measures is the best defence against these evolving threats.

Advanced Malware Can Evade Traditional Security Measures

As cybersecurity tools become more advanced, so does malware. Many modern malware strains are designed to bypass antivirus software, firewalls, and traditional security measures, making them harder to detect and remove.

One tactic used by advanced malware is polymorphism, where the malware constantly changes its code to avoid detection. This means that even if an antivirus program identifies one version of the malware, the altered version can slip through unnoticed. Fileless malware is another growing threat, it doesn’t rely on traditional files but instead operates directly within a system’s memory, making it even harder to spot.

Hackers also use encryption and obfuscation techniques to disguise malicious code, allowing it to bypass security scans. These evolving threats highlight the need for businesses and individuals to go beyond basic antivirus software. Using advanced endpoint protection, behaviour based detection, and regular system monitoring is crucial for staying ahead of these increasingly sophisticated attacks.

Regular Updates and Education Are Key to Prevention

No single security tool can completely eliminate the risk of malware. The best defence is a combination of regular updates, strong cybersecurity practices, and user awareness.

Keeping operating systems, software, and security tools up to date is essential, as many malware infections occur due to unpatched vulnerabilities. Cybercriminals often target outdated systems, knowing they contain security flaws that can be easily exploited. Enabling automatic updates ensures you’re always protected against the latest threats.

Education is just as important. Many malware attacks rely on human error, whether it’s clicking on a phishing email, downloading an infected attachment, or using weak passwords. Training employees and individuals on cybersecurity basics, like recognising suspicious emails, using multi factor authentication, and avoiding public WiFi, can significantly reduce the risk of infection.

Investing in cybersecurity awareness programs and staying informed about emerging threats is crucial in today’s digital world. Prevention is always better than dealing with the consequences of a malware attack.
