The OSSEG Obra Social de Seguros Listed by vicesociety Ransomware Group (reported January 1, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
The incident was reported on 1 January 2022. OSSEG Obra Social de Seguros appeared on the vicesociety ransomware leak site, where the group claims to have stolen internal data during a ransomware attack. No further details on the timing of the intrusion, the method of access, or the volume of material taken have been made public. The number of people affected is listed as unknown.
Who is vicesociety?
Vicesociety is a ransomware group that has been publicly active since at least 2021. Like other ransomware operators, it typically gains access to corporate networks, deploys encryption, and exfiltrates files before demanding payment. The group maintains a leak site where it lists organizations it claims to have targeted, posting samples or directories of stolen material when negotiations fail. Its listings are presented by the group as evidence of successful data theft, though independent verification of each claim is not always available.
About OSSEG Obra Social de Seguros
OSSEG Obra Social de Seguros is an Argentine obra social, a type of not-for-profit health insurance and social-security provider. Organizations of this kind collect and store personal identifiers, employment records, medical histories, and claims information for affiliated workers and their families. Because they handle both administrative and health-related data, they are subject to national privacy regulations governing sensitive personal information.
What was likely exposed
The only detail released is that internal files were allegedly exfiltrated. The exact categories of data contained in those files have not been disclosed. Organizations in the Argentine obra social sector routinely hold names, national identity numbers, contact details, employment information, and medical or claims records. It is not confirmed whether any of these data types were among the material listed by the group.
Why it matters
Health and social-security records can be used for identity fraud, targeted scams, or unauthorized access to medical services. When such data are exposed, affected individuals may face long-term monitoring needs and administrative burdens. For the organization, the incident adds to the operational costs of incident response, potential regulatory scrutiny, and the need to strengthen access controls and encryption practices.
