🥇 First Edition
I decided to include this special section to mark the first edition of High Signal! In this post series, I provide a digest of recently added content to BugBountyDaily that is worth sharing with you.
I started the BugBountyDaily project months ago by publishing Notion pages, then moved to Google Sheets, but I eventually grew tired of the issues I encountered with both. Finally, I went into developer mode and built the dedicated BugBountyDaily website.
It didn't take long to gain traction, soon reaching over 500 unique visitors every day. That success led me to create this newsletter. It was initially named "Daily Digest" until I realized how difficult a daily schedule would be to maintain. Now, I am aiming for three issues a week and have renamed it "High Signal."
The name is self-explanatory. I don't want any noise here or on the BugBountyDaily website. Everything is manually reviewed and curated because I only want high-quality content making it onto the platform. That is why I added a Flag button to each link on the site, allowing you to report items using “Low Quality Content” as the reason.
My main objective is to always follow this concise structure, allowing you to quickly get your daily bug bounty reads while having coffee. At the end, I will add a poll so you can rate the post. Also, I need to implement a feedback request form for this newsletter and the website. It will be available soon!
I hope you enjoy it, as I had a lot of fun coding the website and creating this newsletter 😁
👋 Editor's Note
I’ve moved the newsletter to Beehiiv, which makes my life much easier and helps keep these emails out of spam or promotions folders. Also, if you’re an RSS lover, I just added that feature! Find it in the top right corner of the BugBountyDaily website.
🔥 Top Picks
This is a great two-part guide on postMessage vulnerabilities. I love how it actually explains the Same-Origin Policy (SOP) and why developers need to bypass this security boundary.
Honestly, flawed postMessage origin checks are the reason I've recently earned some nice bounties 😎
Bonus: a good old classic read on postMessage: The pitfalls of postMessage
It’s a crazy mix of venturing where no one else goes—in this case, reverse engineering Java applications—combined with deep technical knowledge of a specific language and framework, experience from previous CTFs, and an amazing team of hackers. I love it 🤯
I recently participated in a Google LHE and hacked Gemini multiple times. Still, this is impressive. It leads me to conclude that we have infinite AI sources and sinks to test daily. Plus, the AI Gold Rush makes it easy to find more attack surface every day.

Not all content makes it to the top picks of the day, but some of it is worth mentioning!
