The Hill Brush Listed by play Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target mid-sized manufacturers and industrial suppliers, using double-extortion tactics that combine system encryption with the public threat of data leaks. In this climate, even organisations outside the most heavily scrutinised sectors can find themselves listed on criminal leak sites, leaving customers, employees and partners uncertain about what may have been taken.

On 20 January 2025, The Hill Brush appeared on the leak site operated by the ransomware group known as play. Public reporting indicates that internal files were claimed to have been exfiltrated during a ransomware attack. The number of people affected remains unknown, and further technical detail has not been released. The listing places the organisation in the United States context according to available summaries.

Breaking down the breach

Public information about the incident is limited to the claim that The Hill Brush was listed by play on or around 20 January 2025. The group asserts that internal files were exfiltrated as part of a ransomware attack. No confirmed figures have been published for the volume of data, the precise date of initial access, the method of intrusion, or the number of individuals whose information may be involved. Whether systems were encrypted, whether a ransom demand was issued, or whether any negotiation occurred has not been disclosed in the available record. The only concrete public element is the leak-site listing itself, which remains an unverified claim by the threat actor until independently confirmed.

Who is play?

Play is a ransomware operation that has been active for several years and is known for a double-extortion model: encrypting victim systems while also stealing data and threatening to publish it if payment is not made. The group maintains a dedicated leak site where it posts the names of organisations it claims to have compromised, often accompanied by sample files or countdown timers. Public reporting on prior campaigns shows that play has targeted a range of sectors, including manufacturing, professional services and local government, typically using common initial-access techniques such as compromised credentials or unpatched remote-access services. In this case the group claims The Hill Brush as a victim; that claim has not been independently verified beyond the listing itself.

About The Hill Brush

The Hill Brush is a manufacturer specialising in industrial and commercial brushes and related cleaning equipment. Organisations of this type typically maintain records covering product design, supply-chain contacts, employee information, customer orders and internal operational documents. A breach at such a firm can affect not only its own workforce but also business customers who rely on its products for hygiene and production processes. Because manufacturing firms often sit in the middle of larger supply chains, any disruption or data exposure can create secondary concerns for partners who share commercial or logistical information with the company.

What data was at risk

The only data category named in public reporting is “internal files” said to have been exfiltrated in the ransomware attack. Exact file types, volumes or categories have not been disclosed. Organisations in the industrial-brush and manufacturing sector commonly hold employee personal details, payroll and HR records, customer and supplier contact lists, order histories, technical drawings, quality-control documentation and internal financial or operational correspondence. Whether any of those categories were among the files claimed by play remains unconfirmed. No statement has been issued that would allow a definitive list of exposed data types to be published.

The real-world impact

For individuals whose information may have been among the internal files, the primary risks are identity-related misuse, targeted phishing that references genuine company details, and potential exposure of employment or contact data. For the organisation itself, consequences can include operational disruption if systems were encrypted, reputational damage among customers and suppliers, and the cost of forensic investigation, notification and remediation. Because the scale of the incident is unknown, the precise number of people who need to take protective steps cannot yet be determined. Business partners who exchange data with The Hill Brush may also need to reassess shared credentials or contractual data-handling arrangements.

If your data was in this claimed breach

If you have a past or present connection to The Hill Brush—as an employee, customer, supplier or contractor—consider the following practical steps:

• Monitor financial and credit accounts for unexpected activity and enable fraud alerts where available.
• Treat unsolicited emails or calls that reference the company with caution; verify any request for personal or payment information through a known official channel.
• Change passwords for any accounts that reused credentials associated with work or supplier portals, and enable multi-factor authentication wherever possible.
• Retain copies of any official notification you receive from the company and follow the guidance it provides.
• Run a free exposure scan of your email address to check whether your information has already appeared in known breach data sets.

Public detail remains limited. Further official statements from The Hill Brush or law-enforcement agencies, if issued, will provide the most reliable guidance on next steps.
