Your credentials might already be for sale
When a major platform gets breached, millions of usernames and passwords end up on dark web marketplaces. If anyone at your Arizona business reused a password from a breached platform on a work account, attackers can buy that credential for a few dollars and walk right into your systems.
This isn’t theoretical. Stolen credentials from Arizona businesses appear on dark web forums regularly. A single compromised password from a Gilbert accounting firm or a Mesa medical office can give an attacker everything they need to access client data, deploy ransomware, or initiate fraudulent transactions.
How dark web monitoring works
Dark web monitoring services continuously scan underground forums, paste sites, and marketplaces for credentials associated with your business domain. When your company’s email addresses or passwords appear in a breach dataset, you get an alert with details about what was exposed and when.
The monitoring covers:
- Credentials (email/password combinations) from data breaches
- Leaked databases containing your domain’s email addresses
- Paste sites where stolen data is shared
- Dark web forums where credentials are traded or sold
- Compromised employee personal accounts that reuse work passwords
What to do when credentials appear
When dark web monitoring detects your credentials:
- Force password reset immediately for the affected account
- Check for unauthorized access in the account’s login history
- Verify MFA is enabled (MFA prevents credential stuffing even with a valid password)
- Scan for lateral movement if the account had access to sensitive systems
- Notify the affected employee and require password changes on personal accounts using the same password
Why MFA is the essential pairing
Dark web monitoring tells you when credentials are compromised. MFA prevents compromised credentials from being used. Together, they form a defense that catches the threat and blocks the attack.
Without MFA, a compromised credential found through dark web monitoring may have already been used. With MFA, even if the password is known, the attacker can’t get in without the second factor. For regulated industries, both FTC Safeguards and HIPAA require MFA as a baseline control.
