Facebook paid $30,000 to Mayur Fartade for discovering an Instagram bug that exposed private posts and stories to anyone. In this email, we’re diving into the full story of how Mayur found this vulnerability, reported it, and ultimately earned a massive bounty.

So, grab a seat because it’s story-time, and we’re talking about how a simple security flaw led to a $30K payout. 😱

Here the story

Mayur Fartade, a security researcher from Maharashtra, comes across a vulnerability in Instagram. We’re talking about a bug that could’ve let anyone see private and archived posts, stories, and reels — all without even following the account. Sounds like a nightmare for privacy, right?

What He Found 👀

Here’s the juicy part: by using something called “media IDs” and some smart API tricks, Mayur discovered a way to unlock the details of these private posts. Likes, comments, the actual images — all up for grabs by just tweaking a few parameters. It was like he had found a hidden backdoor to Instagram's vault!

How Did He Do It? 🧑‍💻

Without getting too technical, here’s a breakdown:

1. He got his hands on the media ID (that’s the unique code for posts, reels, and stories).

2. Sent a simple POST request to Instagram’s ads API.

3. Voilà! He had access to private info like URLs, like counts, and even linked Facebook pages.

But here’s the wild twist: all of this was happening without the user ever knowing. Just imagine the kind of havoc that could’ve caused!

Facebook’s Response 📧

Mayur, being a responsible hacker (a.k.a. ethical hacker), didn’t keep this to himself. He reported the bug to Facebook’s security team on April 16th, 2021, and after a bit of back and forth, they patched it up. It took a little time, but by April 29th, they fixed it.

And guess what? After reviewing his findings, Facebook paid Mayur $30,000 for discovering this vulnerability. 🎉
