    It has been half a year since my last blog post covering an IDOR in a website API. About time to write about something new and hopefully interesting! Having switched my focus from websites to binaries a new world opened up to me.

    Public disclosure

    Hi again! Thank you for reading my third blog post. Happy to share all the details with you on the Insecure Direct Object Reference attack (IDOR) as mentioned in my first blog. It has been resolved by OLX and publicly disclosed on HackerOne, meaning it’s time for a write-up!


  • First bounty, time to step up my game

    What happened

    Hello again and thanks for reading my second blog post! After publishing my first blog I kept on trying to hack different companies and websites. Not as easy as I had hoped for! It took me quite some time to find another security issue after the IDOR in my first month. This SOME issue I found is not to be made public, so I won’t be able to mention company details and will have to mask url’s etc.
