Description: Web malware refers to malicious software that is distributed through web applications or websites. This type of malware can take various forms, including viruses, trojans, ransomware, and spyware, and its main goal is to compromise the security of users’ computer systems. Often, web malware infiltrates devices through deceptive downloads, malicious links, or vulnerabilities in browser software. One of the most concerning features of web malware is its ability to operate covertly, making detection and removal difficult. Additionally, it can be used to steal sensitive information, such as login credentials, financial data, or personal information. The proliferation of internet-connected devices and the increased use of web applications have made web malware an increasingly relevant threat in the cybersecurity landscape. Therefore, it is crucial for users and organizations to implement effective antivirus and antimalware solutions, as well as information management and security event practices, to protect against these threats.
History: The concept of web malware began to take shape in the 1990s with the rise of the Internet. As more users started browsing the web, cybercriminals saw an opportunity to exploit vulnerabilities in browsers and web applications. One of the earliest examples of web malware was the ‘I Love You’ virus in 2000, which spread through emails and affected millions of computers. Since then, web malware has evolved significantly, with the development of more sophisticated techniques such as phishing and the use of exploit kits that allow attackers to compromise systems without users realizing it.
Uses: Web malware is primarily used to steal sensitive information such as passwords, banking data, and other personal information. It can also be employed to install unwanted additional software on users’ devices, which can lead to further security compromises. Additionally, some types of web malware are used to launch distributed denial-of-service (DDoS) attacks against websites, overwhelming their resources and making them inaccessible. Organizations can also be targeted by web malware to gain access to their internal networks and steal valuable corporate information.
Examples: A notable example of web malware is the ‘WannaCry’ ransomware, which spread through vulnerabilities in various operating systems in 2017, affecting thousands of organizations worldwide. Another case is the ‘Zeus Trojan’, which is used to steal banking information and is often distributed through compromised websites. Additionally, phishing attacks that use fake web pages to trick users into revealing their credentials are common examples of web malware in action.
