MasTec has submitted a report to South Carolina authorities regarding a data security incident. This filing indicates that some personal information may have been compromised. The company is currently investigating the scope of the event.

State: SC
Reported: June 5, 2026

MasTec, a global infrastructure construction company, has notified South Carolina state officials about a data security incident. This report was filed on June 5, 2026, as required by state regulations for events that may impact residents' personal information.

Details regarding the specific type of breach and the precise categories of personal information involved were not specified in the public record. Therefore, the exact nature of the compromised data is not yet publicly known, but individuals are advised to remain alert.

At present, MasTec has stated that the incident is under investigation. The official filing does not provide a specific number of individuals potentially affected by this security event, nor does it detail the exact date the breach occurred.

Given the possibility that your personal information may have been exposed, it is prudent to take general protective measures. These include diligently reviewing financial statements and other account activity for any unauthorized transactions or suspicious activity.

Consider placing a fraud alert with credit bureaus as a precaution. Maintaining strong, unique passwords for all your online accounts and enabling multi-factor authentication where available are also highly recommended steps. Staying informed through official company communications and regulatory filings will provide the most accurate updates.
