Megacentro Listed by hunters Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

When a company appears on a ransomware group's leak site, the people whose information may sit inside its systems face practical questions: whether their contact details, work records or other personal data have left the organisation, and what that could mean for everyday risks such as unwanted contact or identity misuse. Public reporting on 20 March 2025 stated that Megacentro had been listed by the hunters ransomware group, with internal files claimed to have been taken. The number of people potentially affected remains unknown, and the precise contents of any files have not been confirmed in available detail.

That uncertainty itself carries weight. Individuals connected to Megacentro—employees, customers, suppliers or partners—cannot yet know whether their data is involved, yet the listing signals that the group asserts it holds material obtained in an attack. Understanding what is known, what is only claimed, and what steps can still be taken is the most useful response while fuller information is limited.

What happened

According to the reported summary dated 20 March 2025, Megacentro was listed by the hunters ransomware group. The listing indicates that data was exfiltrated—copied out of the organisation's systems—while encryption of systems was not reported. The data types named are internal files taken in a ransomware attack. No figure has been given for the volume of material, the number of people whose information may be included, or the exact date the intrusion occurred. Method of initial access, duration of presence inside the network, and any ransom demand remain undisclosed in the public record. The listing itself is a claim by the group; independent confirmation of the full scope has not been published alongside the report.

The group behind it: hunters

Hunters is a ransomware operation that has appeared in public reporting as a group that steals data and then posts victim names on a dedicated leak site, a common pressure tactic intended to force payment or to sell or release the material if demands are unmet. Like many such actors, it typically claims to have exfiltrated files before or instead of encrypting systems, then uses the threat of publication to increase leverage. Prior activity attributed to the group in open sources follows this double-extortion pattern: data theft followed by listing, with varying degrees of actual release. In this instance the group claims Megacentro as a victim and asserts that internal files were taken; those assertions should be treated as unverified claims unless corroborated by the organisation or by independent forensic reporting. No specific statements by hunters about the contents of Megacentro's files beyond the general description of internal material appear in the available facts.

Megacentro and its sector

Megacentro is the organisation named in the listing. Public background on entities operating under similar names often places them in retail, commercial property or large-scale shopping and services environments, sectors that routinely maintain customer records, employee data, supplier contracts, financial documents and operational files. Organisations of this kind typically hold a mixture of personal identifiers, contact information, transaction histories and internal business material. A breach involving such an entity is consequential because the data can touch both individuals who shop or work there and the commercial relationships that keep the business running. Even when the exact industry vertical is not further detailed in the breach report, the presence of internal files raises the possibility that both personal and corporate information could be among what was taken. The absence of confirmed numbers of affected people does not reduce the potential impact on those whose details may be present.

What was likely exposed

The facts state that internal files were exfiltrated in a ransomware attack and that exfiltration occurred while encryption did not. No further breakdown of file types, databases or personal data categories has been disclosed. Organisations comparable to Megacentro commonly store employee records, customer contact lists, invoices, contracts and operational documents; any of these could fall under the broad heading of “internal files.” Because the exact contents remain unconfirmed, it is not possible to state with certainty which specific data elements were taken. Readers should therefore treat the exposure as involving internal material whose personal or commercial sensitivity is still unknown.

• Exfiltrated data: yes (per the reported summary)
• Encrypted data: no (per the reported summary)
• Named data types: internal files
• People affected: unknown
• Further detail on file contents: not disclosed

Why it matters

For individuals, the practical risks centre on the possible misuse of any personal information that may have been included among the internal files—unsolicited contact, phishing that references genuine details, or attempts at identity fraud. Even limited data can be combined with other sources to increase credibility of scams. For the organisation, the consequences include potential regulatory scrutiny, notification obligations where personal data is involved, disruption to operations, and damage to trust with customers and partners. Because encryption was not reported, day-to-day systems may have continued functioning, yet the loss of control over copies of internal files creates a longer-term exposure that cannot be reversed by restoring backups alone. The unknown scale means both the organisation and any affected people must plan for the possibility that material could surface later, whether through sale, leak or further criminal use.

Were you affected?

If you have a relationship with Megacentro—as an employee, customer, contractor or supplier—treat the listing as a prompt to review your own exposure rather than as proof that your data is already public. Practical first steps include monitoring bank and credit accounts for unexpected activity, being cautious of emails or messages that claim to come from the organisation or that reference personal details, and changing passwords on any accounts that reused credentials linked to Megacentro systems. Where available, enable multi-factor authentication. Keep records of any suspicious contact. Because the number of people affected and the precise data types remain unknown, these measures are precautionary rather than evidence of confirmed compromise. Readers can also run a free exposure scan of their email address to check whether that address has already appeared in known breach data sets; such a scan does not prove or disprove involvement in this specific incident, but it can surface other exposures that warrant attention.
