T-Mobile Compromised! - Hackers demand Ransom

Yesterday, there were reports that hackers compromised T-mobile and they were searching for bidders for the data compromised, which acc to them was data till the year 2009

But T-Mobile has said that hackers who claim to have penetrated its network and stolen a treasure-trove of customer data do have a genuine company network document in their possession but that there is no evidence to suggest that personally identifiable information has been put at risk.

Well, I was just wondering if this kind of an attack happens in India to say, Airtel! What then?
