What we know

Below Inc operates within the specialized subterranean construction and engineering sector, providing deep excavation, tunneling, and foundational shoring services for complex civil infrastructure projects. Because the firm handles multi-million-dollar municipal contracts, proprietary engineering schematics, and extensive subcontractor networks, it maintains massive centralized repositories of sensitive enterprise data. This operational scope requires Below Inc to collect and store deeply confidential corporate files, architectural blueprints, proprietary bidding figures, and extensive personnel records for engineers, project managers, and field staff alike.

In 2026, Below Inc formally reported a significant data security incident to the Indiana Attorney General, alerting regulators and affected individuals that its network infrastructure had been compromised by unauthorized actors. Within the engineering and heavy construction sector, breaches of this magnitude frequently stem from sophisticated cyberattacks, such as ransomware deployments or credential-stuffing campaigns that penetrate legacy project-management databases and vendor portals. Once inside, malicious actors can extract gigabytes of unencrypted internal documents, financial ledgers, and employee background files before detection mechanisms trigger.

The exposure resulting from the Below Inc incident encompasses a dangerous cross-section of corporate and personally identifiable information, including full names, dates of birth, Social Security numbers, banking details for direct payroll, and confidential tax documents. When sensitive identifiers like Social Security numbers and financial account details are compromised, victims face immediate, severe risks of identity theft, unauthorized credit openings, and fraudulent tax filings. Furthermore, the leakage of internal corporate credentials and vendor routing numbers exposes individuals and the broader enterprise to targeted phishing schemes and downstream financial account takeover.

As an entity handling sensitive employee and contractor data, Below Inc was legally bound by state and federal data protection mandates, including the Indiana Disclosure of Security Breach Law, to maintain rigorous administrative, physical, and technical safeguards. These legal standards require organizations to utilize robust encryption, multi-factor authentication, and regular vulnerability assessments to secure stored data against foreseeable cyber threats. The occurrence of a successful exfiltration event strongly suggests a failure in these mandatory security protocols, raising serious questions regarding whether Below Inc neglected its duty of care toward the individuals whose data it was entrusted to protect.

Receiving an official data breach notification letter from Below Inc is a formal legal admission that your private information was compromised due to inadequate security measures. Under established consumer protection jurisprudence, this notification confirms that you have sustained an invasion of privacy and possess legal standing to participate in a class action lawsuit seeking accountability and financial compensation. Our firm evaluates these cases on a strict contingency fee basis, meaning you pay nothing out of pocket and owe no legal fees unless we successfully recover compensation on your behalf.
