7 Million OpenSea Addresses Leaked in 2022 Breach, SlowMist Confirms
In a shocking revelation, it has been confirmed that a staggering 7 million email addresses were leaked in a massive breach involving OpenSea, one of the largest NFT marketplaces in the world. The breach occurred as far back as June 2022, and yet, despite its severity, the information remained undisclosed until recently.
The leaked data includes numerous crypto industry professionals, including prominent figures such as Changpeng ‘CZ’ Zhao, Binance’s founder and former CEO. This development poses significant threats to the privacy and asset security of the cryptocurrency sector in the future.
It is essential to note that OpenSea initially alerted its customers about the breach on June 29, 2022, after identifying that an employee of Customer.io, its email automation vendor, had leaked the email addresses to an external party. Subsequently, Customer.io confirmed that the breach also compromised customer data from five other companies, although their identities were not disclosed.
Despite the fact that this incident occurred over two years ago, the repercussions are still being felt today. The attack has provided attackers with a treasure trove of information, enabling them to exploit it for phishing and scams. A recent report by CertiK revealed that phishing attacks emerged as the most costly attack vector in 2024, resulting in losses exceeding $1.05 million from 296 incidents.
Phishing attacks have become increasingly prevalent due to their simplicity and effectiveness. They manipulate users into sharing sensitive information such as passwords, private keys, or wallet addresses by exploiting human vulnerabilities rather than targeting technical systems. In the crypto industry, phishing is particularly devastating since transactions are irreversible once made, making it challenging for stolen funds to be recovered.
The fact that the breach occurred so long ago yet remained undisclosed until now raises serious concerns about data security and responsibility in the industry.
