Digital attackers compromised the website of kitchen and household products manufacturer Tupperware with a credit card skimmer.

One someone had filled in their payment card details, the iframe displayed a “Session timed out” error message. It then reloaded the page with the website’s legitimate payment form while it secretly exfiltrated the user’s information to the attackers.
