grupomarsan.com zoominfo.com/c/grupo-marsan/460771135 Grupo Marsan is a Spanish Tier 2 automotive supplier founded in 1951 in Vigo, Spain, specializing in industrial surface coatings — cataphoresis (e-coating), powder and liquid painting — plus metal stamping, assembly, and JIT logistics, with a capacity of 300,000 parts per day. The company operates plants in Spain (Vigo, Zaragoza), Portugal, and Mexico, and also builds and runs dedicated in-house coating lines inside clients' facilities, supported by its own technology center M-Tech. It works under IATF automotive quality standards within supply chains of major OEMs and Tier 1 suppliers. After a liquidity crisis in 2024, the group was recapitalized with private and Galician public funds (~47.5% held by Xesgalicia and Vigo Activo), and Marcos Oubiña was appointed CEO. FY2024 revenue exceeded €28 million with ~450 employees, and in 2025 the company acquired KATA Aragón, growing to ~500 employees

Attacker assertion only. Establishes: claim date, group, alleged victim.
Unlocks: incident narrative, operational impact. Still no compliance clock.
Unlocks: discovery date, data types, affected count, compliance clock.
Unlocks: materiality, stated response, full audit trail. Ceiling removed.
No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.
