Full breach record for WIZZ AIR HOLDINGS PLC →Threat-actor claim — not a regulatory filing
This row is a claim by the ransomware group Stormous on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

The response stated: "Wizz Air has strong security systems in place, designed to protect the sensitive data of our valued customers and partners." But I would like to know what guarantees you actually offer your customers and others, because this company clearly seems unaware of what’s going on. The breach was published nearly a month ago, and the data has been widely circulated and used. It has also been verified, and it is indeed valid data linked to your employees. Does the company not have any monitoring system? Or perhaps there have been numerous reports of major fraud incidents committed under your name. So, your denial of the breach — which dates back to a month ago — appears more like an attempt to mislead your customers and partners.

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.
