TLDR:

Thousands of Australian customers of popular brands such as Dan Murphy’s and Guzman y Gomez have fallen victim to a hacking scheme known as “credential stuffing.” Scammers are accessing customers’ online accounts and making fraudulent transactions. Leading cybersecurity company Kasada discovered that the problem goes far beyond what was previously known, with accounts from brands including Binge, TVSN, and Event Cinemas also compromised. Kasada’s tracking software showed that 15,000 Australian online accounts had been accessed since late November, and this number continues to rise. Scammers have been purchasing hacked login details from overseas cybercriminals, and some have boasted about using strangers’ money to buy high-value items.
