What Happened

According to public accounts, Boston Capital Holdings LP disclosed that a sophisticated cyber actor gained unauthorized access to files, reportedly by exploiting cloud services. Reports indicate the incident occurred on or about January 16, 2026, and that the company began reviewing a claim of potential unauthorized access on February 12, 2026.

The company's notification letter, dated May 18, 2026, describes the incident as involving a sophisticated cyber actor but does not name the attacker or characterize the incident as ransomware. Separately, the ransomware group LeakNet has claimed responsibility for the attack. That claim is an attacker-side allegation and has not been confirmed by Boston Capital or any regulator.

Important details — including the incident's true scope, the specific data involved for each individual, and the identity of the responsible party — have not been fully confirmed publicly.

What Personal Information May Be at Risk

Based on public accounts and regulatory filings, the information potentially involved varied by individual and may include:

• Names
• Social Security numbers
• Driver's license numbers
• Passport numbers
• Other government-issued identification numbers
• Financial account information (without access codes)

Firms that handle real estate and financial transactions maintain highly sensitive personal and financial information. Exposing Social Security numbers, passport numbers, and government identification, combined with financial account information, can increase the risk of identity theft, fraudulent account creation, tax fraud, and other misuse.

Who May Be Affected

The investigation focuses on Boston Capital Holdings investors, tenants, business partners, and others whose personal information the company maintained. Anyone who has received a data breach notification connected to this incident may face an increased risk of identity theft and fraud and is encouraged to come forward.

Your Legal Options

Edelson Lechtzin LLP is investigating a potential class action to pursue legal remedies on behalf of individuals whose sensitive personal data may have been compromised in the reported breach. A successful case could recover compensation for losses such as lost time, out-of-pocket costs, and loss of privacy, and could push Boston Capital Holdings to strengthen how it protects personal information. The firm will evaluate your rights and potential claims at no cost.

Recommended Steps to Protect Yourself

• Review your account statements and credit reports regularly and stay alert for suspicious activity.
• Confirm whether your information was involved in the Boston Capital Holdings incident.
• Preserve any letters or emails you received about the breach.
• If credit monitoring was offered in your notice, consider enrolling before the stated deadline, and consider placing a fraud alert or security freeze with the three major credit bureaus.
