high severity March 23, 2023 · 4 min read Unverified claim — what this is

Dayton Superior Listed by blackbasta Ransomware Group

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

Dayton Superior, a supplier of concrete and other materials for projects ranging from the Panama Canal to the Trump Ocean Club, is using a data-driven approach to price optimization to help it align prices with all the various markets in which it operates. Headquartered in Miamisburg, Ohio, the 115-year-old global nonresidential concrete construction company has supplied the concrete and other materials for bridges, canals, buildings and stadiums around the world, including the Panama Canal, new World Trade Center Towers and Trump Ocean Club.SITE: www.daytonsuperior.com Address 1125 Byers Rd,

— from Blackbasta’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.
Dayton Superior Listed by blackbasta Ransomware Group

Dayton Superior was listed on the Black Basta ransomware leak site on March 23, 2023. The Ohio-based manufacturer of concrete construction materials appears on the extortion platform after suffering a ransomware attack in which internal files were allegedly exfiltrated. The leak-site listing does not quantify how many records were taken or name the specific data types beyond “internal files.” Anyone whose employment, customer, vendor, or project records touched Dayton Superior may now face heightened risk of identity theft and targeted fraud.

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 582 companies.

Primary Disclosure Details

The Black Basta leak site entry for Dayton Superior states that the company was hit by ransomware and that attackers successfully exfiltrated internal files. No victim count, no list of exposed data fields, and no ransom demand figure are provided in the posting. The disclosure simply states that exfiltrated material is available for download to anyone who visits the onion link. Public reporting on Black Basta indicates the group follows a double-extortion model: encrypt victim systems, then threaten to publish stolen data unless a ransom is paid. Dayton Superior has not released its own public breach notification detailing the incident timeline or scope.

Why This Matters for You and Your Family

Construction suppliers like Dayton Superior maintain extensive records on employees, subcontractors, project bids, pricing models, and customer contacts. If your name, address, Social Security number, or banking details ever appeared in those files, the breach puts you at direct risk. Internal files exfiltrated can include spreadsheets that link personal identifiers to home addresses, phone numbers, and dates of birth. Once such data reaches dark-web marketplaces, it is routinely bundled into fullz packages used for tax fraud, loan applications, and account takeovers. Your family members listed as emergency contacts or dependents are equally exposed even if they never worked at the company.

Doxxing and Identity-Chain Implications

Leaked internal documents frequently contain email addresses, usernames, and project notes that attackers can cross-reference with gaming platforms, social media, and public records. A single credential from a Dayton Superior file can unlock a chain that reveals your children’s Roblox or Fortnite accounts, especially when parents reuse passwords or list family addresses. This creates persistent doxxing pathways: attackers map one leaked email to multiple services, then publish the full household profile. Credential leaks like this one routinely cascade into account takeovers that expose chat logs, payment methods, and geolocation data.

Black Basta’s Known Track Record

Public reporting attributes Black Basta’s emergence to early 2022. The group has since hit hospitals, manufacturers, financial firms, and local governments across North America and Europe. Notable prior victims include the British dental chain Dental Express, the German automotive supplier Continental AG, and several U.S. healthcare providers. Their typical playbook begins with initial access via phishing or compromised remote desktop credentials, followed by rapid lateral movement, data exfiltration, and deployment of custom ransomware. Black Basta usually gives victims a short payment window before publishing samples and then the full archive on their leak site. The group operates both as a ransomware operator and as an affiliate program, which complicates attribution but consistently produces high-volume data leaks.

What to do

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

The Dayton Superior breach is a reminder that even established industrial companies can become gateways to household exposure when internal files reach ransomware groups. Acting quickly on credential hygiene and identity mapping limits how far attackers can travel down the chain. 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.
