On December 24, 2025, the ransomware group lockbit5 listed inspired.ee on its leak site, claiming to have exfiltrated internal files from the organization. The affected entity is Identified Universal McCann, which describes itself as the largest media agency in Estonia and the Baltics.

Inside lockbit5

LockBit operates as a ransomware-as-a-service group that has conducted numerous campaigns since 2019. Its typical approach involves encrypting systems and threatening to release stolen data unless a ransom is paid. The group maintains a leak site where it lists claimed victims. The listing of inspired.ee constitutes the group’s assertion; independent confirmation of the underlying incident has not been provided in available records.

Who is inspired.ee?

Inspired Universal McCann functions as a media agency, handling advertising campaigns, media buying, and related client services across Estonia and the wider Baltic region. Organizations of this type routinely manage contracts, campaign materials, audience data, and internal communications tied to multiple corporate clients. A compromise at such a firm can therefore intersect with information belonging to other businesses and their customers.

What data was at risk

The reported facts name only “internal files exfiltrated in ransomware attack.” No further breakdown of file categories, formats, or specific data fields has been disclosed. Media agencies commonly store client briefings, media plans, financial records, and contact details for staff and partners; however, whether any of these categories were present in the exfiltrated material remains unconfirmed.

The real-world impact

Exposure of internal files can create operational and competitive risks for the agency and its clients. If the files contained personal information, affected individuals could face increased chances of targeted phishing or misuse of credentials. For the organization, the incident may lead to remediation costs, client inquiries, and regulatory scrutiny depending on the jurisdictions and data types involved. Absent a detailed inventory, the exact consequences cannot be quantified from public sources.

Were you affected?

Individuals who have interacted with Inspired Universal McCann as clients, partners, or employees can begin by monitoring their email accounts and financial statements for unusual activity. Running a free exposure scan of one’s email address against known breach repositories provides an initial check on whether associated information has appeared in publicly referenced data sets. Organizations should also review any communications received directly from the agency regarding the incident.
