Manning Building Supplies Listed by Lorenz Ransomware Group

On March 14, 2023, Manning Building Supplies appeared on the leak site operated by the Lorenz ransomware group. The listing states that the construction-supplies company suffered a ransomware attack in which internal files were exfiltrated. The group claims to possess company data and has published a sample as proof, although the exact volume and specific categories of information taken remain undisclosed by both the attackers and the victim.

Details from the Leak-Site Listing

The primary disclosure consists of a single entry on the Lorenz leak portal. It states that internal files were exfiltrated during a ransomware incident and that the data is now held for extortion purposes. No customer record count is provided, no list of exposed data types beyond the generic label “internal files,” and no ransom demand figure is shown. The listing follows the group’s standard format: a company name, proof-of-compromise screenshots or documents, and a countdown clock for negotiation.

Public reporting on Lorenz indicates the group typically uses double-extortion tactics — encrypting victim systems while simultaneously threatening to publish stolen data if the ransom is not paid. In this case the disclosure indicates the company has not yet met the group’s demands, prompting the public listing.

Why This Matters for You and Your Family

When a local building-supplies firm loses control of internal files, the consequences can reach far beyond the company. Vendors, contractors, employees, and customers often have personal information stored in those systems — names, addresses, phone numbers, email accounts, payment details, and employee tax documents. If any of that information belongs to you or someone in your household, it can be used for identity theft, phishing, or targeted scams. Construction-sector breaches frequently expose both business and personal records because suppliers routinely keep customer credit applications and employee payroll files in the same environments.

The incident also highlights how breaches at seemingly unrelated companies can affect ordinary families. If you have ever bought lumber, ordered windows, or worked with a contractor who sourced materials from Manning Building Supplies, your data may now sit in an attacker’s archive.

The Doxxing and Identity-Chain Risk

Stolen internal files often contain spreadsheets that link names to addresses, phone numbers, email accounts, and sometimes dates of birth. Attackers and subsequent buyers of the data can chain these details with usernames found in other breaches, creating a complete identity profile. A single leaked work email can lead to compromise of personal accounts that reuse the same password. Children’s gaming accounts are especially vulnerable because parents frequently use family email addresses or shared passwords that appear in business documents.

Once an identity chain is mapped, doxxing escalates quickly: addresses are sold on underground forums, phone numbers are flooded with SIM-swapping attempts, and family members become targets of personalized extortion. The longer the data circulates unchecked, the harder it becomes to contain.

Lorenz Ransomware Group Track Record

Public reporting attributes the first significant activity by Lorenz to late 2020. The group has targeted mid-sized organizations across manufacturing, healthcare, education, and construction. Notable prior victims include manufacturing firms and regional service providers whose data appeared on the same leak site. Their typical playbook begins with initial access gained through phishing or exploited remote-desktop credentials, followed by lateral movement, data exfiltration, deployment of ransomware, and then dual extortion — demanding payment both to decrypt files and to prevent publication of the stolen documents. The group’s leak site remains active and continues to list new victims on a regular basis.

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.

• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often chain back to the same addresses or parent emails found in business leaks.
• Let the remediation specialists manage takedown requests across data-broker sites and extortion portals on your behalf.
