Your Building Centers Listed by Interlock Ransomware Group

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

Your Building Centers (YBC) is a Pennsylvania-based company with 14 locations throughout Central Pennsylvania. For generations, they have been supplying contractors, builders, remodelers and amateur enthusiasts with name brand building materials. With roots dating back to the early 1900s, YBC and its predecessor companies have created a legacy deeply connected to the communities they serve. Their commitment goes beyond selling materials - they have become the backbone of local neighborhoods, growing with the people and businesses they support. Moving forward, they remain focused on maintaining

Your Building Centers Listed by Interlock Ransomware Group

On July 4, 2025, Your Building Centers, a Pennsylvania-based building materials supplier with 14 locations, appeared on the leak site of the interlock ransomware group. The company, which serves contractors, builders, remodelers, and homeowners across Central Pennsylvania, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of people whose information may have been exposed remains unknown, anyone who has done business with YBC, used its loyalty programs, or provided contact details for deliveries or accounts could be affected.

Already exposed?

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 580 companies.

What Public Reporting Shows

Public reporting indicates that interlock posted YBC to its leak site on Independence Day 2025. The data consists of internal files exfiltrated after the ransomware deployment. YBC has operated for generations with roots in the early 1900s and maintains a strong presence in local communities. No confirmed total of victim records has been published, and the precise types of personal information inside the files have not been independently verified by third parties. The leak site listing itself serves as the primary public evidence of the breach.

Why This Matters for You and Your Family

When a local business like Your Building Centers suffers a breach, the impact reaches beyond the company. Customers, suppliers, and employees often share names, addresses, phone numbers, email addresses, and payment details. If those records were inside the exfiltrated files, your information could now sit on a dark-web leak site. For families, this means increased risk of identity theft, targeted phishing, or unwanted solicitations that waste time and erode peace of mind. Children who have shopped there with a parent or whose information appears on a family account face the same exposure.

Credential leaks like this one frequently cascade into account takeovers on other services where the same email and password are reused. Gaming accounts belonging to you or your children are especially vulnerable because they often rely on the same credentials and can become entry points for further harassment or doxxing.

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.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
