matki.co.uk Listed by cactus Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

People who have dealt with Matki as customers, suppliers, employees or partners may find their personal or business details among internal files that a ransomware group claims to have taken. Public reporting does not yet confirm how many individuals are involved or exactly which records left the company, so the practical risk remains uncertain but real enough to warrant attention.

On 19 September 2024 the group known as cactus listed matki.co.uk on its leak site, stating that internal files had been exfiltrated in a ransomware attack. Until Matki or independent investigators publish further detail, those affected have little official information to go on.

What happened

According to the public listing, cactus claims to have conducted a ransomware attack against matki.co.uk and to have removed internal files. The report date is 19 September 2024. No confirmed figure for the number of people affected has been released, and the precise method of intrusion, the volume of data taken, and any ransom demand remain undisclosed. The listing itself is an unverified claim by the group; Matki has not publicly confirmed or denied the incident in the material available here.

The only data category named is “internal files exfiltrated in ransomware attack.” No further inventory of those files has been published in the source material.

Who is cactus?

Cactus is a ransomware operation that has been active in the public domain for some time. Like many contemporary groups, it typically follows a double-extortion model: encrypting systems while also copying data and threatening to publish it if payment is not made. The group maintains a leak site on which it posts victim names and, in some cases, sample files or full archives. Its listings are claims rather than independently Reported Facts; security researchers treat them as indicators that require corroboration.

Cactus has previously targeted organisations across multiple sectors and geographies. Public reporting attributes to the group the use of custom ransomware, living-off-the-land techniques, and pressure tactics that include timed data releases. None of those general patterns should be read as Reported Details of the Matki incident; they simply describe how the actor is known to operate elsewhere.

matki.co.uk and its sector

Matki is a United Kingdom manufacturer of luxury showers and brassware, established in 1971 and based in Yate, Bristol. The company designs and supplies high-end bathroom products for residential and commercial projects. Public company information places its revenue in the region of $23 million. Organisations of this type routinely hold customer order and contact records, supplier contracts, employee personnel files, design drawings, financial ledgers and internal correspondence.

A breach at a specialist manufacturer can affect both private individuals who have purchased or enquired about products and the wider supply chain that depends on accurate design and delivery data. Because the firm operates in a niche luxury market, the internal files may also contain commercially sensitive technical specifications and client project details.

What was likely exposed

The only category explicitly named in the available facts is “internal files” said to have been exfiltrated. No inventory of those files, no count of records, and no confirmation of personal data fields have been published. Companies in Matki’s sector typically store names, addresses, telephone numbers, email addresses, order histories, payment references, employee details and supplier information. Whether any of those categories were among the files cactus claims to hold remains unconfirmed.

Readers should therefore treat any specific assumption about exposed data types as speculative until Matki or a competent authority issues a formal statement.

Why it matters

If personal contact or financial details were among the internal files, affected individuals face the ordinary risks of phishing, social-engineering calls and identity misuse. Suppliers and trade partners may find commercial terms or project information circulating, which can affect pricing negotiations or competitive position. For Matki itself, the incident raises operational, regulatory and reputational questions that will take time to resolve; UK data-protection rules may require notification of the Information Commissioner’s Office and of individuals if personal data were involved.

Because the scale remains unknown, the practical impact cannot yet be quantified. The absence of confirmed numbers does not mean the risk is zero; it simply means people who have a relationship with the company should remain alert rather than assume they are unaffected.

Were you affected?

If you have been a customer, employee or supplier of Matki, monitor bank and credit statements for unexpected activity and treat unsolicited emails or calls that reference the company with caution. Change passwords on any accounts that reused credentials linked to Matki communications. Consider placing a fraud alert with UK credit-reference agencies if you believe sensitive personal data may have been involved.

You can also run a free exposure scan of your email address against known breach data sets to see whether your information has already appeared in public dumps. That check will not confirm or rule out involvement in this specific incident, but it can surface other exposures that warrant attention while official details remain limited.
