1. Phishing: They mimic real sites to trick you into entering login details, which they then steal.

2. Malicious Code: Hidden code on the site infects your device, capturing keystrokes or passwords.

3. Data Breaches: Hackers exploit website vulnerabilities to steal user data in bulk, including login credentials.

4. Insecure Forms: Sites lacking encryption send your data (including passwords) in plain text, easy for hackers to intercept.

5. Fake Login Portals: Pop-up windows or deceptive login pages lure you into giving away your credentials.

Remember: Be cautious, only use trusted websites, and never share sensitive information on suspicious sites. If unsure, verify a site's legitimacy before entering any personal details.
