Get to know how this happens, and learn how to protect yourself against growing cyber threats.

What Happened in the 23andMe Data Breach?

In 2023, a data breach occurred at 23andMe, a renowned genetic testing company. The breach was prompted by a flaw in the company's opt-in feature, which enabled relatives to communicate with one another. 

This vulnerability exposed millions of consumers' personal information, including names, birth dates, genders, ancestry reports, and raw genetic data.

Hackers especially targeted clients of Chinese and Ashkenazi Jewish origin, implying that the information was being sold or trafficked on the dark web for targeted attacks. 

23andMe reached a $30 million settlement to pay affected customers and strengthen its security protocols.

The hack went unnoticed for five months before being disclosed in October 2023, affecting an estimated 6.9 million users. 23andMe implemented several security measures to avoid future attacks and alerted affected individuals.

What Was the Impact on 23andMe Customers of This Breach?

The data leak at 23andMe had a substantial impact on customer trust. Many clients felt violated and concerned about the privacy of their genetic information. 

While 23andMe responded to the hack and reassured customers, the incident underscored the risks of storing and sharing genetic data.

This Cyberattack Targets Millions of 23andMe Customers

23andMe has finished its investigation, which was helped by third-party forensics specialists. They are currently in the process of notifying concerned customers, as required by law.

“Since detecting the incident, we emailed all customers to notify them of the investigation and are continuing to notify impacted customers, based on applicable laws,” according to 23andMe.

Most of the affected victims (5.5 million) used a feature called “DNA relatives” to find family members, while the rest (1.4 million) used a feature called “Family Tree.”

They also made it clear that the information was gathered by credential stuffing,

The threat actor used the compromised credential-stuffed accounts to access the information.

They also guided their customers to take preventive measures by saying:

“We also required every 23andMe customer to reset their password. In addition, 23andMe now requires all new and existing customers to log in using two-step verification.”

What are the Potential Privacy Risks from Exposed Data?
