Why This Matters
If your email address (or your clients’ email addresses) appears in these breaches, attackers may have access to:
- Passwords (especially if reused across accounts)
- Personal information
- Financial details
- Internal business communications
For Texas law firms and professionals who handle sensitive client data, a compromised email account can quickly lead to:
- Business Email Compromise (BEC) and wire fraud
- Unauthorized access to client portals or cloud services
- Reputational damage and potential professional responsibility issues
What You Should Do
- Check your accounts at haveibeenpwned.com
- Change passwords on any affected accounts (especially if you reused passwords)
- Enable 2-Factor Authentication (preferably app-based or hardware keys, not SMS)
- Use a password manager to generate and store unique passwords
- Monitor for suspicious activity on financial and professional accounts
- Consider email security protections such as DMARC to reduce the risk of your domain being spoofed in future attacks
Data breaches are no longer rare events — they are a constant reality. Staying informed and taking proactive steps is one of the most effective ways to reduce your risk.
