Gaana.com was recently hacked by a Pakistani hacker by the name of MakMan. Accounts of over 10 Million users of Gaana service were hacked into and information was made available to the public until Satyan Gajwani, the CEO of Gaana.com requested the hacker personally to put it down.
Initially the hacker informed the officials about the vulnerability that he found after doing VAPT on the website, to which the company turned a deaf ear. The Gaana hacked incident shows how companies are careless about the security issues concerning their websites even after being intimated about it.
