Weak passwords are one of the most common vulnerabilities exploited by hackers. Here’s how they do it and how you can protect yourself:
How Hackers Exploit Weak Passwords
1. Brute Force Attacks
- What It Is:
- Hackers use automated tools to try every possible password combination.
- Example:
- Trying “password1,” “password2,” etc., until they guess correctly.
- Prevention:
- Use long, complex passwords with a mix of letters, numbers, and symbols.
2. Dictionary Attacks
- What It Is:
- Hackers use a list of common words and phrases to guess passwords.
- Example:
- Trying “admin,” “123456,” or “qwerty.”
- Prevention:
- Avoid using common words or easily guessable patterns.
3. Credential Stuffing
- What It Is:
- Hackers use stolen credentials from one site to access other accounts.
- Example:
- Using a leaked email and password combination to try logging into multiple sites.
- Prevention:
- Use unique passwords for each account.
4. Phishing
- What It Is:
- Hackers trick users into revealing their passwords through fake emails or websites.
- Example:
- A fake login page that captures your credentials.
- Prevention:
- Be cautious of unsolicited emails and verify website URLs before entering credentials.
5. Keylogging
- What It Is:
- Hackers use malware to record keystrokes and capture passwords.
- Example:
- Installing a keylogger through a malicious email attachment.
- Prevention:
- Use antivirus software and avoid downloading files from untrusted sources.
6. Social Engineering
- What It Is:
- Hackers manipulate individuals into revealing their passwords.
- Example:
- Pretending to be IT support and asking for your password.
- Prevention:
- Never share passwords and verify the identity of anyone requesting sensitive information.
