Notably, the hackers were ready to pay $1000 to someone who could help them create the search engine.

Experts’ opinion on the breach

Though Jubilant Foodworks did not seem to have taken any step to avert data getting in the hands of scammers, the said data has the potential to cause serious privacy concerns. The problem is that companies like Domino’s customers share several personal information that can potentially cause financial or even physical harm. Those who tend not to share their address with anyone are searchable only with the phone number.

Independent Security Researcher Sourajeet Majumder published a thread on Twitter explaining the breach. He said that he was able to see all the personal details on the search engine. He said, “On using the search portal made by the threat actor, I was able to find my phone number/email, all delivery addresses, delivery amount and order time & date.”

When OpIndia talked to Sunny Nehra, Admin at Hacks And Security, about the Domino’s data breach, he said, “It has become such a common practice first to have flimsy security and then claim there is no privacy concern. If such companies do not start taking such breaches seriously, they will lose trust among the customers.”

Alon Gal, Co-Founder & CTO, Hudson Rock, had shared the information about the breach in April. He wrote, “Threat actor claiming to have hacked Domino’s India and stealing 13TB worth of data. Information includes 180,000,000 order details containing names, phone numbers, emails, addresses, payment details, and a whopping 1,000,000 credit cards.”

“Plenty of large scale Indian breaches lately, this is worrying,” he had added.
