Duolingo User data Posted on the Dark Web

An unknown party has released the scraped data of 2.6 million DuoLingo users on a hacking forum. While they offered the data set for sale in January for $1,500, it’s now been released on a new version of the Breached hacking forum for 8 site credits, worth only $2.13.

Duolingo, a language learning app, disclosed a data breach in January 2023. The data leaked included usernames, email addresses, profile pictures, and language learning progress.

The breach was caused by a security vulnerability in Duolingo’s API. The vulnerability allowed the attacker to access the personal information of users who had made their profiles public.

Even though most of the scraped data is publicly available, it gives cybercriminals yet another chance to correlate more information with a specific email address or name. Affected users should be wary of phishing emails making use of this information.
