Mercadien PC Certified Public Accountants, a firm providing accounting services, officially reported a data security incident to Texas authorities. The notification, filed on October 13, 2026, confirms that the company experienced an event that potentially exposed personal information. The breach itself was identified as occurring on November 7, 2025.

At present, the public filing does not specify the exact nature of the security breach or the precise categories of personal information that may have been compromised. This means individuals cannot immediately identify specific risks to their financial, identity, or other private data based solely on the public record. However, any exposure of personal information warrants careful attention from affected parties.

The current status of the incident, according to the filing, is that it is under monitoring. This suggests ongoing efforts to assess the full scope and impact of the breach or to oversee recovery and security enhancement measures.

For those who believe their personal information may have been involved, it is prudent to take proactive steps. Regularly review account statements, credit reports, and other financial documents for any unfamiliar transactions or suspicious activity. Consider enabling multi-factor authentication on online accounts wherever possible.

Remaining alert to unsolicited communications, such as emails or phone calls asking for personal details, is also advisable. These details are derived from public regulatory filings and serve as a record for individuals seeking information about this data security event.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
