Study Notes
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.
