An Indian researcher Laxman Muthiyah has become the recipient of a $50,000 award by Microsoft under the company’s bug bounty program. Microsoft awarded the Indian researcher for spotting a vulnerability which could lead to someone’s Microsoft account getting hijacked.
As per Muthiyah, the vulnerability could “have allowed anyone to take over any Microsoft account without consent [or] permission.”
He had earlier found an Instagram rate limiting bug that could help hijack someone’s account. He then checked for the same vulnerability on Microsoft’s account.
Microsoft issued the award of $50,000 through the HackerOne bug bounty platform. The Redmond-based tech giant offers in between $1,500 and $100,000 for reporting bugs.
As per Muthiah, Microsoft was “quick in acknowledging the issue” once he reported it. He also says in a blog post that “The issue was patched in November 2020 and my case was assigned to different security impact than the one expected. I asked them to reconsider the security impact explaining my attack. After a few back and forth emails, my case was assigned to Elevation of Privilege (Involving Multi-factor Authentication Bypass). Due to the complexity of the attack, bug severity was assigned as important instead of critical.”
