BENGALURU | NEW DELHI: The hacker group, which calls itself " Legion " and claims responsibility for the recent hacks of digital accounts of prominent Indians, said the banking system of India is "deeply flawed" and that the group does not believe in a cashless economy, in a secure online conversation with ET."Let me tell you...the banking system of India is deeply flawed and has been hacked several times," said the person who spoke to ET, adding that several other groups also have access to key banking institutions. In the course of the interview, the person also revealed the names of some of the financial institutions "Legion" has targeted. But ET has refrained from publishing their names.Legion, is the same group known to have hacked Congress vice president Rahul Gandhi 's Twitter and email accounts two weeks ago, following that up by hacking into the official accounts of the Indian National Congress . Liquor baron Vijay Mallya , journalists Barkha Dutt and Ravish Kumar , as well as news channel NDTV 's Twitter accounts and email accounts, have also been hacked by the same group. The group has made public the dumps of some of these email accounts.When asked who their next "target" would be, the hacker said: "That's always a surprise. We don't know ourselves. We are going through a certain dump of accounting data." The person ET spoke to, made several references to using narcotic substances including lysergic acid diethylamide (LSD), also known as acid, a potent drug, during the expletive-laced conversation."We don't believe in a cashless economy at all, you need cash, you need cash, that's how things are, sorry mate," the person said.He was also emphatic that if people do not use secure email services, they should suffer. "Get the f*** off the internet if you don't know how to use it. This is a dangerous place where retards gets owned," claimed the hacker.When asked why the group chose the name "Legion", which has Biblical origins, the person said "that was a random name", and "Not a fan of that book (Bible)".They claimed to have been hackers for "more than a decade".Asked about former US spy contractor Edward Snowden and Wikileaks founder Julian Assange , whose work has been hailed for exposing the surveillance and malpractices of governments, Legion said: "Well, unlike them, we can actually hack!" Assange, the hacker said was a "cool guy", and while they respect what Snowden does, "he's only as cool as logging into a computer and dumping confidential d0x(documents)...But neither of them can hack. And they aren't hackers. They are more like 'data dumpers' who collect data from people and organisation like us" Over the past two weeks, several theories have done the rounds about who the hacker might be. While some fingers were pointed at a web hosting service being vulnerable in the case of the Rahul Gandhi, INC and the Mallya hacks, that fell through when the journalists and TV channel were hacked and data made public.The group was also believed to be right wing or government operatives, but the group has categorically denied being political.
