st.com zoominfo.com/c/stmicroelectronics/114508234 Revenue $13.1 Billion STMicroelectronics (ST) is one of the world's largest semiconductor companies and Europe's biggest chipmaker, headquartered in Geneva, Switzerland.

Its core products are microcontrollers (the flagship STM32 family), sensors, analog and power chips, silicon carbide devices for electric vehicles, and chips for data centers and satellites. The company serves over 200,000 customers worldwide — including Apple, Tesla, Bosch, Samsung, and SpaceX — supplying components for cars, smartphones, industrial equipment, and data centers. It operates 14 manufacturing plants across Europe and Asia, employs about 49,000 people, and invests roughly 17% of its revenue in R&D.

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.
