Data exposed Internal files exfiltrated in ransomware attack

On May 6, 2026, Manhattan Fire Safety Corp appeared on the leak site of the ransomware group known as thegentlemen. The New York City-based fire alarm and security services firm had internal files exfiltrated during a ransomware attack, with the data now publicly listed for anyone to download.

Confirmed Facts from Reporting

Public reporting indicates that the incident involved the exfiltration of internal company files from mfsnyc.com. Thegentlemen posted the material on their leak site, as tracked by ransomware.live. Available details do not specify the exact number of records exposed or list particular categories such as customer names, addresses, or payment information. The company, which holds licenses for fire alarm installation and maintenance in compliance with FDNY rules, also provides IT communication systems and structured cabling. No official statement from Manhattan Fire Safety Corp had been widely reported at the time of initial listing.

Why This Matters for You and Your Family

When a local service company like this suffers a breach, the information inside its files can easily include details about residential and commercial clients. If you or your family have ever used a fire safety, security, or cabling provider in the New York area, your contact information, service records, or linked accounts may now sit in an easily downloadable archive. Credential leaks from such incidents often spread quickly across underground forums, giving thieves the raw material they need to attempt account takeovers on email, banking, or other services where passwords were reused.

Even when the initial breach does not list your name, the downstream effects reach ordinary households. Thieves combine these files with other publicly available data to build profiles that lead to identity theft, fraudulent loan applications, or harassing calls. For families with children, the risk extends to any online accounts tied to the same address or parent email.

The Doxxing and Identity-Chain Implications

Ransomware leaks rarely stop at one company’s files. Once internal documents appear online, opportunistic actors search for employee names, vendor lists, customer contracts, and email addresses. These pieces are then fed into automated tools that map connections across social media, gaming platforms, and data-broker records. A single exposed business email can link to personal accounts, phone numbers, and eventually home addresses. Children’s gaming accounts are especially vulnerable because kids often reuse elements of a family email or password, creating a direct chain from corporate breach to a child’s username and location.

Thegentlemen’s Publicly Known Track Record

Public reporting attributes thegentlemen with emerging in recent years as a ransomware operation that combines encryption of victim systems with public shaming on dedicated leak sites. The group has listed a range of organizations, typically small-to-medium businesses, and follows a standard playbook: gain initial access through phishing or exploited remote desktop services, exfiltrate files before deploying ransomware, then demand payment while threatening to release the stolen data. Their extortion style relies on posting samples and full archives on clear-web leak portals if deadlines pass. Exact prior victim counts and technical details remain limited in open sources, but the pattern of steady listings on ransomware trackers is well documented.

What to do

  • Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what this leak may have exposed.
  • Rotate any password you ever used at Manhattan Fire Safety Corp or related services, then enable two-factor authentication through an authenticator app everywhere that same password was reused.
  • Enable continuous DoxxScan monitoring across 15.4 billion breach records and more than 100 platforms so the next time your information surfaces you learn within hours rather than months.
  • Cover the household with DoxxScan family protection that includes dependents and children’s gaming accounts, which frequently become targets when credential leaks cascade into doxxing chains.
  • Let remediation specialists handle the follow-up work, including sending takedown requests to data brokers and monitoring for reappearance of the stolen files.
