Telefonica is investigating the alleged data breach of 120,000 customers and employees

Telefónica is investigating a possible data breach of more than 120,000 of the company’s customers and employees. This is a leak that occurred in March and was reported by a cybersecurity portal. The operator is trying to determine whether there has been a security breach and whether it is related to an external provider. The information collected will be telephone numbers, names or email addresses and postal addresses, not passwords, or logins, not bank accounts.

Data for sale

The company is trying to verify the legitimacy of all this information, which a user posted on a hacker forum in which he claims that the data matches 120,000 customers and employees. This would-be cybercriminal would put all allegedly hacked information up for sale. because it is of no use to him. “But it sure is for some people.”

Telefónica is not the first company to face a possible attack, as Santander also reported mid-month an “unauthorized access” to a financial institution database hosted by the provider, which also affected customers in Spain, Chile and Uruguay. as do all employees and some former employees of the group.
