interstateplastics.com Listed by lockbit3 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to pressure organisations across industrial supply chains by pairing encryption with data theft and public leak-site listings. In that landscape, a May 2023 claim involving a nationwide plastics distributor illustrates how even specialised B2B firms can appear on extortion sites when internal files are alleged to have been taken.

Public reporting states that interstateplastics.com was listed by the LockBit3 ransomware group on or around 24 May 2023. The number of people affected remains unknown, and the only data description given is that internal files were allegedly exfiltrated in a ransomware attack. The listing itself is a claim by the group; independent confirmation of the full scope has not been supplied in the available record.

What happened

According to the reported facts, interstateplastics.com was named on a LockBit3 leak site in connection with a ransomware incident. The date associated with the report is 24 May 2023. Public detail does not describe the initial access method, the duration of any intrusion, whether systems were encrypted, or whether a ransom was demanded or paid.

The record states that internal files were exfiltrated. It does not publish a file count, a data-volume figure, a list of affected systems, or a confirmed total of individuals whose information may have been involved. Those particulars remain undisclosed. The organisation’s appearance on the group’s site should be read as an unverified claim by the actors unless and until further confirmation is published.

Inside lockbit3

LockBit3 is a well-documented ransomware operation that has operated as a Ransomware-as-a-Service model. Affiliates typically gain access to networks, move laterally, exfiltrate data, and deploy encryptors, after which the core group or its partners threaten to publish stolen material on a dedicated leak site if payment is not made. The brand has been linked to numerous attacks on manufacturing, logistics, professional services and other sectors worldwide; its public sites have historically listed victim names, countdown timers and, in some cases, sample files to increase pressure.

Tactics commonly associated with the group in open reporting include phishing or exploitation of exposed remote-access services, use of living-off-the-land tools, and double-extortion—combining encryption with the threat of data release. None of that general pattern should be read as a verified playbook for this specific incident; the facts provided here state only that interstateplastics.com was listed and that internal files were described as exfiltrated. No quotes, ransom amounts or unique claims by LockBit3 about this victim beyond the listing itself appear in the record.

Who is interstateplastics.com?

Interstate Plastics is described in the available summary as a multi-branch, nationwide industrial plastics distributor. It offers plastic sheet, rod, tube and custom profiles, and operates manufacturing facilities that can supply cut-to-size and related services. Firms of this type sit in the industrial supply chain, serving fabricators, OEMs and other commercial customers rather than selling primarily to the general public.

Organisations in this sector ordinarily maintain customer and supplier records, order and shipping data, pricing and contracts, employee information, and operational documents tied to inventory and production. A breach claim matters because disruption or exposure can affect not only the company but also the businesses that rely on it for materials, and because internal files may contain commercial or personal data that third parties would not expect to see published.

The information in question

The facts name the exposed material only as “internal files exfiltrated in a ransomware attack.” No further breakdown—such as whether the files included customer lists, invoices, employee records, credentials, intellectual property or operational schematics—is provided. The number of people affected is listed as unknown.

Companies in industrial distribution typically hold business contact details, account and order histories, shipping addresses, payment-related records, and human-resources data. They may also store technical drawings, custom-profile specifications and supplier agreements. Because the exact contents in this case are unconfirmed, it is not possible to state which of those categories, if any, were involved. Readers should treat any specific data-type claims that go beyond “internal files” as unverified unless corroborated by the organisation or by regulators.

The real-world impact

For individuals whose details might appear in internal business files, risks can include targeted phishing that references real orders or contacts, business-email compromise attempts, and misuse of personal data if HR or contractor records were among the material taken. For customer organisations, exposure of contracts, pricing or shipping patterns can create competitive or fraud-related harm. These outcomes are possible rather than proven; the public record does not confirm what was taken or who was touched.

For the company itself, a ransomware event and a leak-site listing can mean operational interruption, incident-response and legal costs, notification obligations where personal data is involved, and reputational strain with commercial partners. Recovery depends on backups, segmentation and the speed of containment—details that are not described in the available facts. No dollar loss, downtime figure or confirmed victim count is given, so scale remains unknown.

Were you affected?

If you are a customer, supplier or employee of Interstate Plastics, treat the LockBit3 listing as a reason for caution rather than proof that your own data was published. Practical first steps include:

• Watch for unexpected invoices, password-reset messages or requests that reference real orders; verify them through known channels.
• Change passwords on any accounts that reused credentials tied to work or supplier portals, and enable multi-factor authentication where available.
• Monitor financial and credit activity if you have shared payment or identity details with the firm.
• Retain any notice you receive from the company or from regulators and follow its instructions.
• Run a free exposure scan of your email address to check whether it has already appeared in known breach datasets elsewhere.

Public detail on this incident remains limited. Exact file contents, the number of people affected and independent confirmation of the group’s claims have not been established in the facts at hand. Stay alert to official updates from the organisation rather than relying solely on leak-site assertions.
