01

What happened?

Data was gathered by abusing a weak API and was first offered to buyers in January 2023. In August 2023 it spread widely on a well known hacking forum. It held names, email addresses, the languages people studied, experience points and other progress details. Some of this is public by design, but linking it to private email addresses is a lasting privacy risk.

02

What was exposed, and what does it mean for me?

  • Your email addressemail addresses

    Expect messages that look like they come from this service or another one you use, written to get you to click a link or sign in on a fake page.

  • Other detailsnames, spoken languages and usernames

    On their own these carry less risk, but they make a scam message sound more personal.

03

What should I do now?

In this order, for what this data scrape exposed.

1. Expect phishing

  • Be wary of messages that urge you to act fast, ask for personal details, or link to an address that is slightly off.
  • If a message might be genuine, do not use its links or phone numbers. Go to the site by typing its address yourself.
