What happened?

Breaking news as of this December, 2020: Popular cryptocurrency hardware wallets, Ledger, had their eCommerce database hacked in June of 2020. Now we are seeing massive customer personal information leaks, including over 1 million emails, and 272,000+ personal information leaks, including shipping addresses, phone numbers.

Check here to see if your personal information was leaked in this attack.

Similar to the Equifax hack in 2017 that exposed over 100 Millions US household privacy data, the 2020 Ledger data breach has impacted the global cryptocurrency community. Equifax data breach was believed to be the wake up call of data privacy regulations such as GDPR (General Data Protection Regulation, enforced in EU), and the recent CCPA (California Consumer Privacy Act). Would Ledger violate these data privacy laws?

AnChain.AI feels the responsibility to raise public awareness on the upcoming fraud and cyber-crimes. As a leading blockchain cybersecurity company, our threat intelligence depicts the impact is actually underestimated at this moment. This concerns us on a personal level as well. We have employees, investors, friends and families that are impacted by this massive data breach.
