I bypassed “How I hacked Google’s bug tracking system itself for $15,600 in bounties.” Here’s how.

Hello Everyone!

I was reading some write-ups, and I came across this bug which I liked: “Getting a Google employee account.” It was a nice find by Alex Birsan. I started testing the issue tracker, and I was trying to see if I could get a Google account. Then looking around in issue tracker, I noticed in the browse components there were two public issue trackers. So I clicked on Android Public Tracker.

I could see bugs reported to Android there. To report a Bug in the Android public issue tracker, you can send an email to:

where android’s component id is 190923.

I could see that my issue got listed in the public issue tracker. I got a confirmation email from A reply to this email would be directed to:

I responded to that email, and a comment was posted in the conversation. I could add a Google email to see if I could get a confirmation code. To test this I clicked on Forwarding and POP/IMAP in Gmail settings and added the Google email to the forwarding email address. I was surprised to see I got a confirmation code in the Android public issue tracker.

There are two parts here to get a Google account Signup and verification. I could verify a Google account, but I could not signup for an account, so my report was closed as Won’t Fix. I almost gave up, because after the initial fix I could not use my email. But I decided to give it one last try.


Then I started visiting every sub-domain of Google to see if I could use a email to signup. This new signup page appeared (see below). Initially, I could not find “Use my current email address instead” to get it to go to Then you would click on Create an account, and you could see there was an option to use your current email address.


My heart rate increased after seeing the new signup page. I began to sign up using the email and then it asked me to verify by entering the code.

Verify your email address

I was waiting for the verification code in the conversation, and then I received the verification code in the email and the conversation in the issue tracker.


After successfully signing up for the Google Account, I reopened the issue. The impact here was that you can access which requires a Google account. Besides this, I tried to upgrade my account to Gmail now as I had a Google account. I added it to my Gmail, and I was able to send an email using from

If you try to spoof email, your mail will land in spam. But my email appeared in the inbox, and it was from so an attacker could pretend that they were a Google employee.

Nice catch!


It was 9:50 PM when I was looking for bugs, and finally, the most awaited email arrived: I was getting $3133.70. I could not sleep the whole night.

Thanks to Alex Birsan — this would not have been possible without his write-up. I learned a lot from reading his write-up. Also, thanks to Avinash Jain and Alex Birsan for taking the time to review the draft.

Thanks for reading!
