Clemens Construction Listed by dragonforce Ransomware Group
If you are a customer of Clemens Construction, here’s what is being claimed, and what it would mean for you.
Clemens Construction was listed on DragonForce's leak site. DragonForce claims to have stolen internal data. This is the group's claim, not a confirmed finding.
Editor’s note: The claims described below originate from a ransomware group’s leak-site posting and have not been independently verified by GalaxyWarden. A listing of this kind is an assertion made by the group during an extortion attempt. It is not evidence that a breach occurred, and we report it as a claim rather than as a finding.

On August 2, 2025, Clemens Construction appeared on the leak site of the dragonforce ransomware group. The Philadelphia-based firm, which handles renovation and construction projects for hotels, schools, and commercial buildings, is claimed to have had internal files exfiltrated after a ransomware attack. Public reporting indicates the exposed materials include banking, insurance, financial, and HR documentation along with audit records and client files. The number of people whose personal information may now be public remains unknown.
Reported Details of the Breach
Available reporting describes the incident as a classic ransomware operation in which attackers gained access, encrypted systems, and then exfiltrated data before demanding payment. The files listed on the dragonforce leak site contain sensitive records that almost certainly include names, addresses, dates of birth, Social Security numbers, financial account details, and employment information belonging to employees, clients, and business partners. No exact count of affected individuals has been released, and Clemens Construction has not yet issued a public statement detailing the timeline or scope.
August 2, 2025 marks the date the data was published on the group’s onion site, according to ransomware.live. The leak site post highlights categories such as banking records, insurance documents, HR files, audits, and client documentation. These materials often contain the exact details needed to commit identity theft or launch further attacks against anyone named inside them.
Why This Matters for You and Your Family
When a local business like Clemens Construction loses control of HR, financial, and client files, the people whose information sits in those folders face real risk. If you or anyone in your family ever worked there, hired them for a project, or appeared as a vendor or reference, your data may now be in criminal hands. A single leak like this can supply thieves with enough to open accounts in your name, file fraudulent tax returns, or target your family with convincing phishing emails.
Construction firms routinely store copies of driver’s licenses, tax forms, insurance certificates, and banking details for employees and subcontractors. Once those records leave the company’s control, they do not expire. Thieves trade and resell them for years. For an ordinary family, that translates into months or years of vigilance against identity theft, unexpected credit inquiries, and suspicious activity on accounts you thought were safe.

The Doxxing and Identity-Chain Risks
Leaked HR and client files rarely stay isolated. A name, email address, or phone number from one document can be combined with gaming usernames, social-media handles, or school records found in other breaches. Attackers follow these links to map an entire household. Children’s gaming accounts are especially vulnerable because parents often reuse passwords or security questions that appear in work files. A single credential leak can cascade into account takeovers, doxxing, and harassment that reaches every member of the family.
Identity-chain mapping turns one breach into a road map. Once attackers link an email from Clemens Construction to a reused password on a gaming platform or family email account, the exposure grows. Public reporting indicates this pattern appears in many ransomware cases where initial leaks fuel follow-on extortion or identity theft.
Dragonforce’s Publicly Known Track Record
Public reporting attributes the dragonforce ransomware group with emerging in late 2023. The group has claimed responsibility for attacks on organizations across multiple sectors, often listing victims on leak sites hosted on the dark web. Their typical playbook involves initial access through phishing or exploited remote desktop services, followed by data exfiltration, encryption of victim systems, and extortion demands backed by the threat of publishing stolen files. Notable prior victims have included companies in manufacturing, healthcare, and professional services, though exact details vary across incident reports.
What to do
- Run a DoxxScan to map every link between your emails, phone numbers, handles, and real-world identity so you can see exactly what chains back to the Clemens Construction files.
- Rotate any password you ever used at Clemens Construction or any related vendor account, then replace it with a unique passphrase and enable 2FA through an authenticator app rather than text messages.
- Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you learn within hours instead of months.
- Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which frequently become targets when work credentials leak.
- Let remediation specialists handle takedown requests and broker removals for you while you focus on securing accounts and watching for fraudulent activity.
