## Payment Firm Nayax Allegedly Fully Breached, Actor Threatens 100TB Release With Over 1 Billion Card Records

A threat actor using the alias **TheSyndicate** claims to have fully compromised **Nayax**, an Israeli global payments and fintech company (NASDAQ: NYAX, TASE: NYAX.TA), stating they have been inside its systems for almost a year. The actor announces that over **100TB of exfiltrated data** will be released on **July 21st**, allegedly including **over 1 billion card-data records**, full KYC data, complete prepaid card data, customer identities, transaction histories, internal API keys and credentials, infrastructure maps, source code, and financial records. They say a portal to query the card data and download raw files will follow. The claim is **unverified** and the data has not yet been released.

### ⚠Potential impact

If genuine, this would be one of the largest payment-related breaches on record. The combination of payment card data at billion-record scale, KYC identity data, and internal API keys and credentials would enable large-scale payment fraud, identity theft, and further attacks against Nayax's merchants and systems. The exposure of source code and infrastructure maps would compound the risk. The actor has announced a future release rather than posting data, so at this stage the scope is a claim. No data, samples, or the actor's release site are reproduced here. The claim is unverified.

### iStatus

Unverified 

This is a pre-announcement: the actor claims a full compromise and says the data will be released on July 21st through a portal, with a Telegram update promised beforehand. No data has been posted yet, and neither the release site nor the contact channel is reproduced here. The claim is **unverified** and Nayax has not publicly addressed it.
