Oxfam data breach: 1.8M accounts exposed
Severity: high · Patch status: no-fix-needed · Since 2021-03-02
In January 2021, Oxfam Australia was the victim of a data breach which exposed 1.8M unique email addresses of supporters of the charity. The data was put up for sale on a popular hacking forum and also included names, phone numbers, addresses, genders and dates of birth. A small number of people also had partial credit card data exposed (the first 6 and last 3 digits of the card, plus card type and expiry) and in some cases the bank name, account number and BSB were also exposed. The data was subsequently made freely available on the hacking forum later the following month. Exposed data: bank account numbers, dates of birth, email addresses, genders, names, partial credit card data, payment histories, phone numbers, physical addresses. The breach dates from Jan 20, 2021; Have I Been Pwned loaded it on Mar 2, 2021.
What to do
- If you had a Oxfam account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
