Naftali Group Listed by Sinobi Ransomware Group

If you are a customer of Naftali Group, here’s what is being claimed, and what it would mean for you.

Naftali Group was listed on Sinobi's leak site. Sinobi claims to have stolen internal data. This is the group's claim, not a confirmed finding.

Naftali Group Listed by Sinobi Ransomware Group

On September 28, 2025, the Naftali Group, a New York City-based real estate development firm, appeared on the leak site of the sinobi ransomware group. Internal files were allegedly exfiltrated during a ransomware attack, and the company’s data is now publicly listed for anyone to access.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that sinobi posted Naftali Group’s internal documents on its dark web leak page. The firm, founded and led by Miki Naftali, specializes in acquiring and restoring high-value properties in prime locations. Available reporting describes the exposed material as internal files, though the exact volume and full list of contents remain unconfirmed by the company. No specific count of affected individuals has been released, but real estate development firms routinely hold sensitive records on clients, employees, vendors, and property transactions.

September 28, 2025 marks the public listing date. The attack follows the typical ransomware pattern of initial compromise, data theft, and subsequent extortion pressure.

Why This Matters for You and Your Family

When a company like Naftali Group suffers a breach, the information inside its files can directly touch your life. If you have ever bought or rented from them, worked with them, or been part of a transaction they handled, your name, address, phone number, email, financial details, or Social Security number may now sit in a publicly downloadable archive.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
