EUROFILM ΜΑΝΤΖΑΡΗΣ Α.Ε Listed by incransom Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

People connected to EUROFILM ΜΑΝΤΖΑΡΗΣ Α.Ε. face the practical possibility that internal company files have been taken and may circulate beyond the organisation’s control. When a ransomware group lists a business, the immediate concern for employees, partners and anyone whose details sit inside those files is whether personal or operational information could be misused for fraud, phishing or further intrusion.

Public reporting on 12 August 2025 states that the Greek firm has been named by the incransom ransomware group, which claims to have exfiltrated internal files. The number of people affected remains unknown and the precise contents of the files have not been independently confirmed.

Breaking down the breach

According to available records, EUROFILM ΜΑΝΤΖΑΡΗΣ Α.Ε. was listed by the incransom ransomware group on or around 12 August 2025. The group asserts that internal files were exfiltrated during a ransomware attack. No public confirmation of the attack method, the volume of data taken, the exact date of intrusion, or any ransom demand has been released. The number of individuals potentially affected is listed as unknown. Contact details associated with the organisation in the reporting include info@mantzaris-film.com, (+30) 27410 54900, info.ath@mantzaris-film.com and (+30) 212 000 0001; these appear to be ordinary business contact points rather than confirmed exposed personal data.

Because the listing originates from the threat actor’s own claims, independent verification of the full scope remains limited. No further technical indicators or forensic findings have been disclosed in the material available for this account.

Who is incransom?

incransom is a ransomware operation that follows a well-documented double-extortion model: encrypting systems while also copying data and threatening to publish it if payment is not made. Groups of this type typically maintain leak sites where they name victims and, in some cases, release samples or full archives. Public tracking of such actors shows they often target mid-sized commercial organisations across multiple sectors, using common initial-access methods such as compromised credentials or unpatched remote services, then moving laterally to locate valuable files.

In this instance the group claims EUROFILM ΜΑΝΤΖΑΡΗΣ Α.Ε. as a victim and states that internal files were exfiltrated. No additional statements attributed specifically to this listing—such as file counts, screenshots or deadlines—appear in the reported facts. Readers should treat the listing as an unverified claim until corroborated by the organisation or independent investigators.

EUROFILM ΜΑΝΤΖΑΡΗΣ Α.Ε and its sector

EUROFILM ΜΑΝΤΖΑΡΗΣ Α.Ε. operates in the film and media sector in Greece, consistent with its trading name and the domain mantzaris-film.com. Companies of this type typically manage production schedules, contracts with freelancers and suppliers, financial records, customer or distributor lists, and internal correspondence. They may also hold personal data of employees, cast, crew and business partners.

A breach in this sector is consequential because media firms often store commercially sensitive material—unreleased content, licensing agreements, payment details—and personal information required for payroll, tax and collaboration. Exposure of such material can disrupt operations, damage commercial relationships and create lasting privacy risks for individuals whose data is held.

The information in question

The only data type named in the available facts is “internal files exfiltrated in ransomware attack.” No inventory of specific document categories, personal identifiers or financial records has been published. Organisations in the film sector commonly retain employee records, contractor invoices, client contact lists, project files and correspondence. Whether any of those categories were among the files claimed by incransom is unconfirmed.

Because the precise contents remain undisclosed, it is not possible to state as fact which individuals or which data fields are involved. The absence of a confirmed count of affected people further limits assessment of scale.

The real-world impact

For people whose information may sit inside the claimed files, the concrete risks include targeted phishing that references real projects or colleagues, identity-related fraud if personal identifiers were present, and unsolicited contact using leaked email or telephone numbers. For the organisation itself, potential consequences include operational disruption, loss of commercial confidentiality, regulatory notification duties under applicable data-protection rules, and the cost of investigation and remediation.

None of these outcomes is guaranteed; they depend on what was actually taken and whether the data is later released or sold. At present the public record supplies only the group’s claim of exfiltration of internal files and the listing date of 12 August 2025.

What to do if you're exposed

If you have a past or present relationship with EUROFILM ΜΑΝΤΖΑΡΗΣ Α.Ε.—as staff, contractor, supplier or client—treat the situation as a possible exposure until more detail emerges. Practical first steps include:

• Monitor bank and credit accounts for unexpected activity and enable transaction alerts where available.
• Treat unsolicited emails or calls that reference the company or its projects with heightened caution; verify through known official channels before responding.
• Change passwords on any accounts that reused credentials linked to work email, and enable multi-factor authentication.
• Keep records of any suspicious contact that appears to draw on internal knowledge.
• Run a free exposure scan of your email address against known breach data sets to check whether your information has already surfaced elsewhere.

Further official statements from the company or Greek authorities, if issued, will provide the most reliable next guidance. Until then, measured vigilance is the proportionate response.
