Union Home Mortgage Exposed Client Information In Massive Data Breach, Lawsuit Alleges

Case Overview: A class action lawsuit claims Union Home Mortgage failed to protect customer data, exposing thousands to identity theft risks.

Consumers Affected: Borrowers and applicants whose information was compromised in the June 2025 data breach.

Court: U.S. District Court for the Northern District of Ohio

Union Home Mortgage had insufficient security protocols that led to a major data breach allegedly exposing thousands of clients’ personal details to cybercriminals, a new lawsuit claims. 

The Ohio-based lender, which operates in nearly every U.S. state and processes around $5 billion in loans annually, is accused of failing to safeguard the personal and financial data it collects from customers, MPA Mag reports. 

The lawsuit claims that the company’s inadequate cybersecurity measures allowed hackers to access sensitive information, including names, Social Security numbers, government-issued IDs, and birth dates.

Plaintiff Says Breach Led To Identity Theft Risks And Financial Losses

The case was filed in federal court in Ohio by resident Victor DiMarco. DiMarco alleges that Union Home Mortgage’s promises to protect client privacy were not backed by effective security practices. 

He argues the breach has caused measurable harm, ranging from loss of time and money to deal with the fallout, to the devaluation and theft of their personal information. His complaint also highlights the ongoing risk of identity theft and fraud that victims now face.

Hackers Accessed Client Data Across Multiple States, Lawsuit Claims

According to court filings, Union Home Mortgage first detected suspicious activity on June 25, 2025, and confirmed by late August that customer data had been accessed without authorization. 

The company notified affected clients around mid-September, informing them that their personal information may have been compromised. Reports filed with state attorneys general show that at least 1,650 residents in Washington and more than 24,000 in Texas were affected, though the total number of victims could be much higher.

Union Home Mortgage Accused Of Ignoring Cybersecurity Standards

The complaint accuses Union Home Mortgage of failing to follow standard security protocols and Federal Trade Commission guidelines for protecting sensitive information. It alleges the company has not explained which systems failed, how hackers gained access, or how similar incidents will be prevented in the future. 

DiMarco says the breach has led to financial losses, invasion of privacy, and the ongoing risk that their stolen data will be used for fraud or identity theft.

Data Breach Lawsuits Surge Against Major U.S. Companies

Union Home Mortgage joins a growing list of major companies hit with lawsuits over cybersecurity lapses. Allianz Life Insurance is being sued after a breach allegedly exposed personal and financial data from 1.4 million customers. 

Victoria’s Secret faces litigation over a May 2025 breach that leaked customer information, while Cooper University Health Care and Globe Life are also defending suits related to delayed or inadequate breach notifications.

DiMarco’s complaint accuses Union Home Mortgage of negligence, breach of contract, and unjust enrichment. The suit seeks damages and a court order requiring the company to strengthen its data protection systems and provide ongoing credit monitoring to affected customers.
