Overview of Malware Attacks in Cyber Security

"Malware" is a fusion of two words: "malicious" (meaning harmful) and "software" (meaning computer programs). It's a term used to describe software intentionally created to cause harm or damage. This digital troublemaker lurks in the darker corners of the virtual world, ready to create chaos for unsuspecting computer systems, complex networks, and innocent devices. This category of harmful software, commonly known as "malware," is remarkably crafty. It takes on various forms, each meticulously designed to execute its destructive plans. Let's delve deeper and unveil some of the ways it can wreak havoc.

Types of Malware Attacks

Malware comes in various forms and can be employed for a range of malicious purposes, from data theft to system disruption.

• Viruses: These intrusive programs attach themselves to legitimate files and spread when the infected file is executed. The notorious Melissa virus, which propagated via email, and the ILOVEYOU virus, causing significant damage by overwriting files, exemplify the destructive potential of viruses.
• Worms: Worms are self-replicating entities that exploit vulnerabilities to spread across networks without requiring user intervention. The Blaster worm, targeting Microsoft Windows, significantly disrupted networks by exploiting a critical vulnerability.
• Trojans: Concealing their true intent, Trojans often deceive users by masquerading as legitimate software. The Zeus Trojan, for instance, created backdoors in systems, enabling cybercriminals to steal sensitive financial information, impacting millions of users worldwide.
• Ransomware: Ransomware encrypts a victim's data and demands payment for decryption. The WannaCry attack, which affected over 200,000 computers in 150 countries, showcased the global reach and financial impact of ransomware attacks.
• Spyware: Operating stealthily, spyware surreptitiously collects sensitive information from users without their knowledge. The FinFisher spyware, known for its invasive capabilities, raises grave concerns about user privacy.
