The Araneta Group Listed by osiris Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 10, 2025, the osiris ransomware group listed The Araneta Group on its leak site, stating that internal files had been exfiltrated during a ransomware attack. The number of individuals affected is not known, and no further details on the timing, volume of data, or confirmation of the claims have been made public. The incident is relevant because the organization operates across property, hospitality, and leisure sectors and maintains records on approximately 12,000 employees.

What happened

The only confirmed public information is the listing itself. The osiris group claims to have obtained internal files from The Araneta Group through a ransomware operation. No independent verification of the data volume, encryption status, or payment demands has been reported. The exact date of the intrusion and the method of initial access remain undisclosed.

Who is osiris?

Osiris is a ransomware operator that maintains a leak site to publish the names of organizations it claims to have targeted. Groups of this type typically encrypt systems and copy files, then use the threat of public release to pressure victims. The listing of The Araneta Group follows the pattern these actors have used with other entities, though the specific claims regarding this organization have not been corroborated by outside sources.

The Araneta Group and its sector

The Araneta Group is a privately held Philippine conglomerate with operations in property development, food service, leisure and entertainment, and hospitality. It comprises five primary business units and maintains the domains aranetacity.com and aranetagroup.com. Organizations in these sectors routinely collect employee records, vendor contracts, guest information, and operational documents related to real estate and service delivery.

The information in question

The facts state that internal files were exfiltrated. No inventory of specific data categories has been released. Organizations of this type commonly hold personnel files, financial records, customer or guest details, and proprietary business documents, but the precise contents of any exfiltrated material remain unconfirmed.

What's at stake

Individuals whose information appears in internal files may face risks of identity misuse or targeted fraud if the material is later distributed. The organization itself could encounter operational disruption, regulatory scrutiny, or loss of trust from employees and business partners. Because the scale of exposure is unknown, the full extent of these consequences cannot yet be assessed.

What to do if you're exposed

Anyone employed by or doing business with The Araneta Group should treat the listing as a signal to review their personal accounts and monitor for unusual activity. Practical first steps include:

• Changing passwords for any work-related or linked personal accounts and enabling multi-factor authentication.
• Reviewing bank and credit statements for unauthorized transactions.
• Requesting a copy of personal data held by the organization if permitted under local privacy rules.
