Willis Klein Listed by projectrelic Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On November 11, 2022, the ransomware group projectrelic listed Willis Klein on its leak site, claiming the company had been hit in a ransomware attack that involved the exfiltration of internal files. The number of people affected remains unknown, and public detail beyond the group's claim and the broad description of internal files is limited. For a long-established supplier of plumbing, hardware, and related products, any confirmed exposure of internal material raises practical questions about business records, employee information, and customer or partner data that such firms commonly hold.

The listing itself is an unverified claim by the threat actor. No independent confirmation of the full scope, method, or precise contents has been supplied in the available record. What follows sets out what is known, what is typical for this type of actor and sector, and what steps people can reasonably take if they believe they may be affected.

What happened

According to the reported information, Willis Klein was listed by the projectrelic ransomware group on November 11, 2022. The group asserted that internal files had been exfiltrated in a ransomware attack. No public figure has been given for the number of people affected, and the available facts do not disclose the initial access method, the duration of any intrusion, the volume of data taken, or whether encryption of systems also occurred. Timing beyond the listing date, ransom demands, and any negotiation outcome are likewise undisclosed. The core public fact is the leak-site listing and the claim of internal-file exfiltration.

Who is projectrelic?

projectrelic is a ransomware group known publicly for double-extortion operations: encrypting victim systems while also copying data and threatening to publish it on a dedicated leak site if payment is not made. Like other groups in this category, it typically advertises victims on its site with varying levels of sample data or file listings to pressure organizations. Public reporting on the group has described it as following patterns common to ransomware crews of the period—targeting a range of commercial victims, using leak sites as leverage, and moving relatively quickly from intrusion to public listing. Specific technical claims about tools or affiliates used against Willis Klein are not part of the available facts; the group's listing of this victim should be treated as its own assertion rather than independently verified detail.

Who is Willis Klein?

Willis Klein is a company founded in 1960 with multiple divisions that supply decorative plumbing, door hardware, custom bathroom cabinets and furniture, and commercial hardware. Organizations in this sector typically maintain supplier and customer records, order and shipping data, employee and payroll information, design or product specifications, and internal financial and operational files. A breach claim against such a firm is consequential because the business sits at the intersection of manufacturing, wholesale distribution, and commercial construction supply chains. Disruption or exposure can affect not only the company itself but also partners, contractors, and end customers who rely on accurate orders, warranties, and account details. The age and multi-division structure of the firm also mean it may hold long-running historical records alongside current operational data.

What was likely exposed

The facts state that internal files were exfiltrated in a ransomware attack. No further breakdown of file types, databases, or record counts has been disclosed. Organizations of this kind commonly hold employee contact and HR data, customer and dealer account information, purchase orders, invoices, product specifications, and internal correspondence. It is not confirmed whether any of those categories were among the material projectrelic claims to have taken. Exact contents remain unconfirmed; readers should treat any specific data-type assertions beyond “internal files” as unverified unless corroborated by the company or independent reporting.

What's at stake

For individuals, the practical risks depend on what was actually in the exfiltrated files. If employee or customer records were included, possible outcomes include targeted phishing, identity-related fraud attempts, or misuse of contact and account details. For the organization, stakes include operational disruption, potential regulatory or contractual notification duties, reputational harm with dealers and commercial clients, and the cost of investigation and remediation. Because the scale and precise data types are unknown, the concrete impact on any given person cannot be stated as fact. The situation underscores the value of monitoring financial and email accounts and treating unexpected messages that reference the company or its products with caution.

If your data was in this claimed breach

If you have a past or present relationship with Willis Klein as an employee, customer, or partner, treat the projectrelic claim as a reason for heightened vigilance rather than proof that your specific records were taken. Change passwords on related accounts, enable multi-factor authentication where available, and watch for phishing that impersonates the company or its suppliers. Review financial statements and credit activity for unfamiliar activity. You can also run a free exposure scan of your email address to check whether your information has already surfaced in known breach data sets. Keep records of any suspicious contact and report clear fraud attempts to the relevant authorities and financial institutions. Public detail on this incident remains limited; official statements from the company, if issued, should be preferred over unverified claims on leak sites.
