What happened
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.
What data was exposed
- Email addresses
- Employers
- Job titles
- Names
- Payment methods
- Phone numbers
- Physical addresses
What to do right now
- Watch your card and bank statements. Set up transaction alerts, and consider a card freeze or replacement if the exposure included full card numbers.
- Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
- Watch for targeted phishing mail. A leaked home address makes postal and doorstep scams more convincing.
- Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
- Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
- Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
