What to do
- Expect more phishing emails that mention this service. Do not click links in them; go to the site directly.
- Be wary of texts and calls that seem to know your details.
- Check your bank and card statements, and ask your bank about a new card if you see anything odd.
- Turn on two-step verification wherever it is offered, and use a password manager.
About this breach
In April 2026, online training company Udemy was the victim of a “pay or leak” extortion attempt perpetrated by the ShinyHunters group. The data was subsequently leaked publicly and contained 1.4M unique email addresses belonging to customers and instructors. The data also included names, physical addresses, phone numbers, employer information and instructor payout methods including PayPal, cheque and bank transfer.
