Introduction:

Malware is software, code, or program designed to perform malicious activities on your computer system without your consent. This generic term now refers to all kinds of viruses, worms, Trojans botnets etc but not all malware are viruses. Every year there are a lot of malware attacks on businesses and organizations that cause billions of dollars in financial loss.

The Evolution of Malware

The evolution of malware has been marked by increasing sophistication, with attackers continually developing new methods to infiltrate systems, steal data, and disrupt operations as the first forms of malware were relatively simple such as "Creeper" (1971), "Elk Cloner" (1982) and "Melissa" (1999) the newer forms are more dangerous and harmful. After the 2000's the rise of sophisticated threats along with worms and botnets such as "ILOVEYOU" (2000), and "Blaster" (2003) caused significant damage by spreading quickly and exploiting vulnerabilities in operating systems.

In the 2010s Advanced Persistent Threats (APTs) and Ransomware emerged as one of the most significant threats with attacks like "WannaCry" (2017) causing widespread damage.

Latest  Malware Threats:

Ransomware, Spyware, and Adware are some of the latest types of malware attacks. Ransomware-as-a-Service (RaaS) model has made ransomware accessible to less sophisticated attackers targeting everything from individuals to organizations.

Malware Threats Affecting Individuals:

Ransomware and spyware can lock users out of their systems or steal sensitive personal information, leading to significant psychological and financial distress.

Malware Threats Affecting Organizations:

For businesses, ransomware can disrupt operations, leading to downtime and loss of revenue. Data breaches result in the theft of customer data and other sensitive information causing serious legal repercussions and damage to reputation.

Common Types of Malware:

Let's discuss some of the most common types of malware:

Ransomware:

Ransomware is the malware used by cyber criminals to demand a ransom amount from the user. They encrypt the victim's files and data or lock them out of the system with a ransom note. Ransomware can spread through phishing emails, malicious websites, or exploit kits. The victims face serious financial losses and data damage due to ransomware attacks.

Real-World Examples of Ransomware Attacks:   

A notable example of a ransomware attack was "WannaCry"(2017), which infected more than 200,000 computers with the Microsoft Windows operating system. The attackers threatened the victims to permanently delete their data if they did not pay the ransom amount which was in Bitcoins. Most of the compromised systems were those that did not update the recent security update released by Microsoft. This ransomware attack caused $4 billion in losses across the globe.

Spyware:

Spyware is the type of malware that is used for spying on victims' systems without their knowledge. It can record activities like internet activities, passwords, and financial details. Some spyware can even secretly record audio and video footage using a webcam or microphone.

Real-World Examples of Spyware Attacks:

Famous examples of spyware attacks include “Pegasus” and “Finfisher”. Both were developed for spying purposes on the authority's consent. Finisher is commercially used to spy and steal information while Pegasus was built for spying on high profile targets. Pegasus was designed by the NSO group to spy through the iPhones of journalists, lawyers, political dissidents, and human rights activists.

Adware:

Adware is used to run unwanted advertisements on a user's device for financial gains through advertising revenue. It is not directly harmful but it causes a bad screen experience due to unwanted popups and banners. Adware mostly approaches your system through free software or is installed through deceptive downloads.

Real-World Examples of Adware:

“Fireball” the Chinese adware can hijack browsers, redirect search queries, and collect users' data. It can run any code on victim computers–download any file or malware, manipulating infected users' web traffic to generate ad revenue. Adware can prominently distribute any additional malware.

Protection Strategies against Malware:

By following some of the protection strategies against malware attacks you can keep your system secure and intact.

Use of Antivirus and Anti-Malware Software:

Always use updated versions of antivirus and anti-malware tools on your system to ensure robust security. They can scan through the files, email attachments, and websites for any potential malware before they reach and damage your system.

Malwarebytes is one of the best anti-malware software with features like Real-Time Protection,  Browser Guard, Malware Removal, and anti-ransomware technology. It scans and removes any kind of malware even before it damages your system.

Protecting Your Online Activity:

It is recommended to use a reliable VPN service to protect your online activity. NordVPN is an excellent choice if you need robust security features.

NordVPN Threat Protection:

NordVPN Threat Protection is a feature within the NordVPN service that helps in blocking malicious websites, ads, and trackers. It blocks malware, ads, and web trackers and alerts users if their credentials are found on the dark web. It is the most recommended tool for enhanced protection.
