Question

what are the different threats to a windows system (denial of service, ransomware, etc) and how do they attack a system?

Explanation:

1. Malware (e.g., Ransomware): Encrypts files, demands ransom. Spreads via phishing, infected files.
2. Denial of Service (DoS): Overwhelms system with traffic/requests, causing unavailability. Uses botnets or fake requests.
3. Phishing: Tricks users into giving credentials via fake emails/websites, enabling unauthorized access.
4. Trojan Horses: Disguised as legitimate software, installs malware, steals data or gives control to attackers.
5. Spyware: Secretly collects user data (keystrokes, browsing) via infected downloads, weak security.
6. Zero - Day Exploits: Attack unpatched vulnerabilities (OS/apps) before fixes exist, via malicious code execution.

Answer:

• Ransomware: Encrypts data, demands ransom; spreads via phishing/infected files.
• DoS: Overwhelms with traffic/requests; uses botnets/fake requests.
• Phishing: Tricks for credentials; via fake emails/sites.
• Trojan Horses: Disguised software, installs malware; steals data/gives control.
• Spyware: Collects user data; via infected downloads/weak security.
• Zero - Day Exploits: Attack unpatched vulnerabilities; via malicious code.
