Hey friend 👋,

Just got back from a trip to Alaska. It was beautiful weather, but it was still too damn cold for this Canadian boy. 🥶

I mean, just look how icy blue the water was in Glacier Bay...

One good thing about the trip was that I got to drink a lot of hot chocolate and catch up on some reading. I just finished reading The Wires of War: Technology and the Global Struggle for Power. It was an interesting read from a Googler in the middle of it all, and it really got me thinking about how technology has changed the way we fight digitally. If you like the intersection of technology, politics, and global power, this is worth picking up.

Articles in May

I was so swamped in May getting ready and going on my trip to Alaska. Even still, I did keep up with my articles:

• I published a guide that showed you how to avoid conflict when you approach a company and report a vulnerability you found as a security researcher.
• I showed you how to attack APIs by tainting data in weird places. That included discovering ways to modify API requests during testing to corrupt data and manipulate code flow, allowing you to uncover new vulnerabilities.
• I created the ultimate link library of my articles so you can learn how to get started as an API hacker. This is a great first link to share with someone new who wants to get into this field. Sharing is caring. Please share.
• I taught you how to find tenant-bleed vulnerabilities in multi-tenant apps and APIs that expose cross-tenant data leaks (CTDL) during your security testing.
• I talked about the lucrative economics of API hacking and showed you how to make more money in less time on a consistent basis by focusing on API pentesting rather than bug bounty hunting.
