Modern browsers store website data in localStorage and sessionStorage. It’s convenient — but not secure.
If malicious code enters your browser, it can read this stored data and steal login tokens, personal information, or access to your accounts.
Why It’s a Threat
- Data in DOM Storage is not protected
- Attackers can take over accounts without passwords
- Most attacks happen silently, with no warnings
- Older browsers like Internet Explorer are high-risk
How Users Can Stay Safe
- Use modern browsers
- Clear site data regularly
- Remove suspicious extensions
- Keep your system updated
How Companies Can Reduce Risk
- Avoid storing sensitive data in localStorage
- Use secure, HttpOnly cookies
- Protect websites from XSS
Limit third-party scripts
