A watchdog is to investigate Twitter after a hacker claimed to have private details linked to more than 400 million accounts.
The hacker, “Ryushi”, is demanding $200,000 (£166,000) to hand over the data - reported to include that of some celebrities - and delete it.
Ireland’s Data Protection Commission (DPC) says it “will examine Twitter’s compliance with data-protection law in relation to that security issue”.
Twitter has not commented on the claim.
The data is said to include phone numbers and emails, including those belonging to celebrities and politicians, but the purported size of the haul is not confirmed. Only a small “sample” has so far been made public.
Twitter has so far not responded to press inquiries about the claimed breach.
That’s a big breach …
