Sparta Blog

Profile narrative

Sparta Blog is a threat actor known by that alias and has been associated with operations originating from Russia. The actor maintains a leak site where it publishes data obtained from compromised entities. No additional aliases or alternative names have been publicly attributed to Sparta Blog in the available sources. Its geographic origin is noted as Russia, though no further detail about infrastructure or hosting is provided.

In September 2022 Sparta Blog listed the IT services provider Sercom Informatica SL on its leak platform. Accompanying the listing, the actor released sample files taken from Sercom's customers, specifically mentioning Hospital Puigcerda. The disclosed samples contained IP addresses, plain‑text passwords, domain and subdomain information, and staff email addresses from the hospital's IT department. DataBreaches attempted to contact both Hospital Puigcerda and Sparta Blog for confirmation, but received no reply from either party. The leak did not include any indication of ransomware deployment or extortion demand linked to the published data.

The same Databreaches article that reported the Sparta Blog activity also covered unrelated incidents involving the hacktivist group Guacamaya and the Everest ransomware group. Those incidents involved email leaks from Latin American military and police organizations and a claimed sale of network access to Argentina's Ministry of Economy. Sparta Blog's appearance in the report situates it within a broader context of simultaneous data‑exposure events across multiple sectors. No public attribution ties Sparta Blog to a state sponsor, criminal consortium, or any specific ideology. The actor's observed behavior is limited to the publication of exfiltrated data without accompanying malware or tooling descriptions. Consequently, the known profile of Sparta Blog is defined primarily by its publishing activities and the specific Sercom Informatica SL disclosure.
