In July 2026, Pioneer Construction, headquartered in Grand Rapids, Michigan, experienced a data breach. The Akira ransomware group claimed responsibility for the attack and the exfiltration of 168 GB of corporate data. This incident was publicly disclosed by Akira, not via an official company announcement.
The exfiltrated data reportedly includes scanned employee personal documents such as passports and driver's licenses, project details, financial records, client information, contracts, and confidential correspondence. The exact number of affected individuals remains unconfirmed. While the company operates nationwide, specific states affected beyond Michigan have not been detailed.
As of July 17, 2026, no official breach notification letter, company statement, or State Attorney General filing has been publicly released. Legal and regulatory responses are likely in their initial stages, and further details, including the number of affected individuals and specific state impacts, may emerge with formal notifications from the company.
