Malware Overview

Malware is malicious software designed to harm or gain unauthorized access to a computer system.
Understanding different types of malware is crucial for cybersecurity.

Viruses

Viruses are self-replicating malware that attaches to other files or programs.
They require user interaction (e.g., running an infected file) to spread.
Viruses execute when the infected file is run, seeking out other files to infect.
Examples: File Infectors (attach to executables), Boot Sector Viruses (infect boot sectors of disks)
Prevention involves using reputable antivirus software and avoiding untrusted sources/email attachments.

Worms

Worms are self-replicating malware that spreads across networks without needing a host file.
They exploit vulnerabilities in systems to propagate automatically.
They rapidly send copies of themselves to other computers on the network.
Examples: Morris Worm, WannaCry
Prevention includes keeping systems patched, using firewalls, and implementing intrusion detection/prevention systems.

Ransomware

Ransomware encrypts a victim's files or locks their system, demanding a ransom payment for restoration.
It spreads through phishing emails or infected downloads.
Encryption makes files unusable.
Examples: CryptoLocker, Ryuk
Prevention involves regularly backing up data to an offline location and being cautious about links and attachments.

Spyware

Spyware secretly monitors user activity and steals information like passwords, credit card details, and browsing history.
It operates in the background, collecting data without user knowledge.
It often comes bundled with other software or through malicious websites.
Examples: Keyloggers (record keystrokes), adware (displays ads).
Prevention involves using anti-spyware software, avoiding suspicious websites, and being wary of software installations.
