Proactive Investors - Black-hat criminal hacker group ShinyHunters has allegedly stolen the data of 30 million Banco Santander (BME:SAN) customers and staff across Spain, Chile and Uruguay.
Santander disclosed a security breach earlier this month, but the extent of the breach has just come to light after hackers put the data up for sale on the dark web.
According to X account ‘Dark Web Informer’, ShinyHunters is selling the data for $2 million (£1.57 million).

28 million credit card numbers and six million account numbers and balances are allegedly in the data package.
Santander told the BBC is "proactively contacting affected customers and employees directly”.
ShinyHunters is linked to a Ticketmaster hack that stole hundreds of million of user details, ticket sales and even card data mere days ago.
Proactive has reached out to Santander to ask weather UK-based accounts have been affected.
