Recommendations for Personal Data Protection

Although the breach appears to concern public legislative records rather than individual personal data, it’s prudent for all users—even officials—to:

• Monitor communications for phishing attempts using leaked document context
• Use unique, strong passwords and enable two-factor authentication on any administrative accounts
• Be wary of suspicious emails or messages referencing leaked legislative content
