Chennai: Just a month after winning USD 30,000 from Facebook for spotting a flaw in Instagram, Chennai-based security researcher Laxman Muthiyah on Monday said that he has yet again discovered a new account takeover vulnerability on the photo and video-sharing app. This time he has won USD 10,000 as part of the social network's bug bounty programme.

The new vulnerability that Muthiyah spotted was similar to the one he reported in July and allowed anyone to hack Instagram accounts without consent permission. Facebook has now fixed the vulnerability that Muthiyah reported.
