Peroni Pompe Listed by donutleaks Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to pressure industrial and manufacturing firms by pairing system disruption with the threat of public data leaks. Listings on criminal leak sites have become a routine feature of that landscape, often appearing before independent confirmation of what was taken or how far an intrusion went. Against that backdrop, the Italian pump manufacturer Peroni Pompe was named in mid-2023 by the group known as donutleaks.

Public reporting on 3 July 2023 recorded that donutleaks had listed Peroni Pompe and claimed to have exfiltrated internal files in a ransomware attack. The number of people affected remains unknown, and independent detail on timing, method and full scope is limited. The listing itself is a claim by the group, not a verified disclosure by the company.

What happened

According to the reported summary tied to the listing, donutleaks asserted that it had obtained internal files from Peroni Pompe through a ransomware attack and stated that “the full package of yours data will be uploaded within 30 day,” urging the organisation to make contact “as soon as possible for preventing the…” further publication. The report date associated with the listing is 3 July 2023. No confirmed figure for individuals affected has been published, and public sources do not describe the initial access method, the duration of any intrusion, or whether systems were encrypted in addition to data theft. Beyond the group’s own statements on its leak site, independent corroboration of the volume or precise contents of the material remains undisclosed.

Who is donutleaks?

Donutleaks is known publicly as a ransomware operation that follows the now-common double-extortion model: encrypting or disrupting systems while also copying data and threatening to release it if a ransom is not paid. Like other actors in this category, the group maintains a leak site on which it names victims, posts samples or full archives, and sets deadlines intended to increase pressure. Its listings are claims made by the operators themselves; they do not automatically establish that every asserted file set is authentic or complete. Prior public activity attributed to the name has followed the same pattern of industrial and commercial targets, though specifics of any single campaign must be treated as the group’s assertions unless separately confirmed. In this case, the only concrete statements available are those attached to the Peroni Pompe listing—namely the claim of internal-file exfiltration and the 30-day upload warning.

About Peroni Pompe

Peroni Pompe is an established manufacturer whose activities, according to the material accompanying the listing, have since the 1950s centred on the design and production of oscillating process pumps, supplied as tailored solutions to industrial customers. Firms in this sector typically sit inside longer supply chains for chemicals, energy, water treatment and other process industries. They hold engineering drawings, customer and supplier records, commercial contracts, employee information and operational documentation. A breach affecting such an organisation matters because the data can reveal proprietary designs, pricing and relationship details, and personal information of staff or contacts, with potential knock-on effects for partners who rely on the company’s equipment and continuity.

What data was at risk

The facts available name the exposed material only as “internal files exfiltrated in a ransomware attack.” No inventory of file types, no record counts and no confirmation of whether customer, employee or technical data were included have been published in the public report. Organisations of this kind ordinarily maintain design and manufacturing files, quality and compliance records, procurement and sales data, and human-resources material. Those categories are typical; they are not confirmed as present in this incident. Exact contents therefore remain unconfirmed, and any assessment of sensitivity must stay within that limit.

What's at stake

For individuals whose details may have been among internal files, the practical risks include targeted phishing that references real projects or colleagues, credential stuffing if work email addresses and passwords were stored together, and longer-term exposure of personal identifiers. For the company, stakes include possible disclosure of proprietary pump designs and process know-how, disruption of customer and supplier relationships, regulatory notification duties where personal data are involved, and the operational cost of investigation and recovery. Because the scale of the alleged exfiltration and the identities of affected parties are unknown, the concrete impact cannot yet be measured from public information alone. The group’s threat to publish within a stated window simply adds time pressure; it does not itself prove the completeness of the haul.

If your data was in this claimed breach

If you have a past or present connection to Peroni Pompe—as an employee, contractor, customer or supplier—treat the possibility of exposure seriously even while details stay limited. Change passwords on any related accounts, enable multi-factor authentication where available, and watch for unsolicited messages that cite internal projects or contacts. Monitor financial and identity accounts for unusual activity. Retain any official notices the company may issue. As a further check, you can run a free exposure scan of your email address to see whether it has already appeared in known breach data sets, then act on any confirmed hits by updating credentials and tightening account recovery options.
