Posillico Listed by akira Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Posillico was listed by the Akira ransomware group on January 05, 2026, after internal files were exfiltrated in a ransomware attack affecting an undisclosed number of people. Individuals connected to the organisation should check whether their information was exposed and take protective steps.
Ransomware operations continue to target mid-sized and specialized firms that hold detailed operational and personnel records. On January 05, 2026, the Akira ransomware group listed Posillico on its leak site, claiming to have stolen nearly one terabyte of corporate data during a ransomware intrusion. The number of individuals affected remains unknown, and the company has not issued a public statement confirming the scope or contents of any exfiltration.
What happened
The incident came to light when the Akira group posted Posillico on its data-leak site. The group stated that it had exfiltrated internal files and would soon publish almost 1 TB of material, including SQL databases. No independent confirmation of the volume or specific files has been made public, and details such as the initial access method or the date of the intrusion have not been disclosed.
The group behind it: akira
Akira is a ransomware operation that emerged in early 2023 and has since conducted intrusions against organizations in multiple countries. The group typically employs double-extortion tactics, encrypting systems while also copying data for later publication if a ransom is not paid. Its leak-site listings serve as the primary public signal of claimed compromises; such listings constitute an assertion by the actors rather than verified evidence of the data’s authenticity or completeness.
About Posillico
Posillico operates in the construction sector, focusing on infrastructure projects and related services. Organizations of this type routinely maintain records concerning employees, project documentation, contracts, financial transactions, and insurance matters. A compromise at such a firm can therefore expose both corporate operational data and personal information belonging to staff and business partners.
What was likely exposed
The only confirmed element is that internal files were removed from Posillico’s systems. The Akira group claims the material includes employee personal information, project records, contracts and agreements, detailed financials, and insurance files. Because no independent verification or official disclosure has occurred, the precise categories and volume of data remain unconfirmed.
The real-world impact
Individuals whose information appears in the claimed dataset could face risks of identity misuse or targeted phishing. For the organization, the exposure of project and financial records may affect ongoing commercial relationships and regulatory obligations. The absence of a confirmed count of affected people limits the ability to assess the full scale of potential harm at this stage.
What to do if you're exposed
Anyone concerned that their information may have been involved should monitor accounts for unusual activity and consider placing fraud alerts with credit agencies. Organizations that hold similar data are advised to review access logs and incident-response procedures.

Publicly posted by akira — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
