solidere Listed by devman Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 6, 2025, the ransomware group devman listed Solidere on its leak site and claimed to have exfiltrated internal files from the Lebanese company. Public records show no confirmed count of affected individuals and no verified details on the volume or contents of the material beyond the group’s assertion of a ransomware operation. The incident occurs amid a sustained pattern of ransomware activity targeting organizations that manage critical infrastructure and urban development records, where data exfiltration followed by public listing has become a common pressure tactic.

What happened

The listing appeared on the date noted above. No independent confirmation of the breach has been published, and the organization has not released a statement detailing the timeline, attack vector, or scope. The reported summary indicates only that internal files were claimed to have been taken during a ransomware attack. Scale, duration of access, and whether encryption was also deployed remain undisclosed.

The group behind it: devman

Devman is a ransomware operation that follows the established pattern of encrypting systems, exfiltrating data, and publishing samples or directories on a dedicated leak site when ransom demands are not met. Such groups typically gain initial access through phishing, compromised remote-access tools, or unpatched vulnerabilities, then move laterally to locate and copy files before deploying encryption. Prior public reporting on the actor has documented similar listings against entities in multiple sectors, with the leak-site post serving as the primary signal that negotiations have stalled.

Who is solidere?

Solidere, formally the Société Libanaise de Développement et Reconstruction, is a joint-stock company established in 1994 and tasked with the reconstruction, development, and management of Beirut’s Central District. It holds responsibility for restoring historical buildings, attracting investment, and supporting tourism initiatives while exercising certain governmental powers over urban planning. As a private entity with public-sector functions, it maintains records related to property ownership, development contracts, financial arrangements, and regulatory approvals.

What data was at risk

The only data category named in connection with the listing is internal files exfiltrated during the claimed ransomware attack. No further breakdown of file types, personal identifiers, or specific datasets has been released. Organizations of this type routinely hold correspondence, contract documentation, financial ledgers, and planning records; however, the precise contents of any exfiltrated material remain unconfirmed.

What's at stake

Exposure of internal files could reveal details of ongoing development projects, contractual obligations, and communications involving residents, investors, and public authorities. For individuals whose information appears in those records, potential consequences include targeted fraud or unwanted contact. For the organization, the incident may complicate project timelines, increase scrutiny from regulators, and require extended forensic and remediation work.
