[engineering] NTP B.V. (trading as NTP Infra / NTP Groep) is a Dutch civil engineering contractor headquartered in Hattem, Gelderland. They build roads, lay cables, install sewers, and perform ground works across the Netherlands. With 150–200 employees, offices in Hattem, Enschede, and Zevenaar, and a 2024/2025 acquisition of Aannemingsbedrijf Dubbink B.V., they are a typical mid-market Dutch “aannemingsbedrijf” — government contracts, municipal works, private developments. Their file server contained everything: 10+ years of operations, every employee's personal files, the complete HR/payroll system exports, every network device configuration, every project bid, and every financial record.

Not assessable
Evidence ladder
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.
