What happened?

In 2016, the South African cinema company Ster-Kinekor had a security flaw which leaked a large amount of customer data via an enumeration vulnerability in the API of their old website. Whilst more than 6 million accounts were leaked by the flaw, the exposed data only contained 1.6 million unique email addresses. The data also included extensive personal information such as names, addresses, birthdates, genders and plain text passwords.

What should you do?

Verify whether the notice applies to you

Compare the organization, dates, and information categories with any notice you received. Use contact details you independently confirm.

Secure affected accounts

Change exposed or reused passwords, begin with your email account, and turn on multi-factor authentication where available.

Protect identity information

Review your credit reports and consider a free credit freeze if identity information could support new-account fraud.

Expect targeted phishing

Treat unexpected breach follow-ups with caution. Do not use links or phone numbers in a suspicious message; contact the organization directly.

Choose actions that match the information involved. If you find signs that someone is using your identity, the Federal Trade Commission provides a personal recovery plan at IdentityTheft.gov.
