World’s largest NFT marketplace reports major data breach

On June 30, the popular NFT marketplace Opensea with colossal $13 billion valuation in January, warned users of email phishing attack after a major data breach.

The NFT giant reported that a staff at Customer.io, an email vendor contracted by OpenSea, misused their employee access to download and share email addresses of OpenSea’s users and newsletter subscribers with an unauthorized external party.

The scale of the security breach appears massive:

If you have shared your email with OpenSea in the past, you should assume you were impacted.

The company added that it’s working with Customer.io in an ongoing investigation and has reported the incident to law enforcement.

The other day, a major data breach has exposed the sensitive information of every person with a California permit to carry a concealed weapon. The California Department of Justice has been hit by the data breach as part of the launch of its 2022 Firearms Dashboard Portal, according to the Fresno County Sheriff's Office, which said it was informed of the leak by the California State Sheriffs' Assn.
