John Gallin & Son Listed by dragonforce Ransomware Group

If you are a customer of John Gallin & Son, here’s what is being claimed, and what it would mean for you.

Our firm was founded in 1886 by John Gallin, an Irish immigrant. The firm continues to be run by the Gallin family, now in its fourth generation of management. We work on projects located throughout the New York City metro area. Additionally, we have special expertise working with the unique demands of Manhattan high-rise buildings. Our clients comprise a cross-section of area businesses, including finance, retail, insurance, real estate, and law. We also have a great deal of experience working with non-profits and schools.

— from DragonForce’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
John Gallin & Son Listed by dragonforce Ransomware Group

On July 24, 2024, construction firm John Gallin & Son appeared on the leak site operated by the dragonforce ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the family-run business, which has operated in the New York City metro area since 1886. Anyone whose personal or financial records passed through the company’s systems may now face heightened exposure.

Details in the Leak-Site Listing

The dragonforce leak site, tracked via ransomware.live, states that John Gallin & Son data was stolen and is now published. The disclosure indicates that internal files were taken but does not specify the volume of records, the exact file types, or the number of individuals affected. No ransom demand figure or payment deadline is listed in the public entry. The company’s own description notes it serves clients in finance, retail, insurance, real estate, law, non-profits, and schools, suggesting project-related documents, contracts, billing records, and correspondence could be among the stolen material.

Why This Matters for You and Your Family

When a local construction and project-management firm like John Gallin & Son is hit, the ripple effects reach ordinary people. If you or your family have ever lived or worked in a Manhattan high-rise, attended a school the firm serviced, or been a client of one of its business partners, your name, address, contact details, or financial arrangements may sit inside the exfiltrated files. Internal files exfiltrated in ransomware attack often contain spreadsheets, PDFs, and emails that map real people to addresses, phone numbers, and payment histories. Once published, that information circulates on dark-web forums and can be reused for identity theft, phishing, or targeted scams against you or your relatives.

The Doxxing and Identity-Chain Risks

Stolen internal files rarely stay isolated. A single leaked email or invoice can link your home address to usernames, phone numbers, or children’s school records. Attackers then chain these fragments across multiple breaches to build a complete profile. This is exactly how doxxing escalates: one construction-firm leak supplies the street address that, combined with a later retail breach, reveals your full household. Gaming accounts belonging to your children are especially vulnerable because the same passwords or recovery emails are often reused. Credential leaks like this one routinely cascade into account takeovers on Steam, Roblox, or Discord, exposing chat logs, linked phone numbers, and even voice recordings that further enrich an attacker’s dossier.

Dragonforce’s Known Track Record

Public reporting attributes dragonforce with emerging in late 2023 as a ransomware-as-a-service operation. The group has claimed responsibility for attacks on organizations across North America and Europe, often targeting mid-sized firms in construction, manufacturing, and professional services. Their typical playbook begins with initial access through phishing or exploited remote-desktop credentials, followed by exfiltration of sensitive files before encryption. They then pressure victims with dual extortion: threats to publish the data combined with demands for payment to prevent release. The John Gallin & Son listing fits this pattern, showing the group’s willingness to name smaller, long-established family businesses that may lack enterprise-grade defenses.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by the service.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours rather than months.
  • Rotate any password you used at John Gallin & Son or its partners anywhere it is reused, and switch on 2FA through an authenticator app instead of SMS.
  • Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that often chain back to the same address or recovery email.
  • Let remediation specialists manage takedown requests for any exposed personal documents found on data-broker or leak sites.

The incident underscores that even decades-old local firms can become gateways to personal exposure when ransomware groups strike. Staying ahead requires more than reactive checks. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage including children’s gaming accounts.

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.
