Visa has confirmed to Vice News that a major data breach occurred at its payment systems network, affecting a number of credit card payment systems.

The breach, which occurred on April 20, impacted the Visa Mastercard Payment system, according a post on the company’s Twitter account.

The company said that the breach involved “authentication and/or unauthorized access to the Visa SecureWorks Platform, which is designed to protect the integrity of payment card data.”

Affected cards included Visa cards, Visa Electron cards, and Visa Visa Signature cards.

Visa said it is working with the card issuers to prevent further loss of information and to provide customers with the ability to change their card.

It also said that Visa will provide credit card customers with an update on the status of their accounts, including an explanation of what was compromised.

Visa said that it was notified by Visa’s customer service team of a data breach on April 27, 2018.

“The company has begun an investigation into the matter, and as a result, the company is in the process of removing all Visa Master Card payment systems from the Internet,” the company said.

A spokesperson for Visa said that, following the incident, it worked with the affected card issuer to determine how the breach occurred.

“Visa is taking immediate steps to ensure that our systems are secure,” the spokesperson said.

The Visa Payments platform, which was created in 2014, is one of the most popular payment card systems for consumers.

It processes more than 5 billion payments every month.

In 2017, Visa issued a report that found that fraudsters had targeted its platform for malware, ransomware, and other cyberattacks.

Visa has said that its payment platform is one example of the way the industry works to protect against cyberattacks by making it more secure.
