"The volume of data breached is currently unknown. Cyble claims that attackers have demanded 10 ETH, equivalent to USD 4,000." —The attackers clearly don't know anything about Paytm. $4000 is likely their marketing budget per minute!

Seriously though, Paytm users have had to face fraud on their platform for so long (for instance, here: https://www.moneycontrol.com/news/business/all-you-need-to-k...) that I'm surprised they haven't got some steps in order already.

The weakest link in cybersecurity is the people though. And PayTM has a lot of them!
