Newsletter # 21 - Scanning a process' memory using LLDB Mar 26 2020

Hello, and welcome to issue #21!

How is everything going? I hope you and yours are safe. What a crazy world we are living in now, right? I guess every generation thinks they are living a period that will change history. Who knows, maybe this time the changes that will come after all this will make us change the world to be a better place.

Anyways, with everyone working remotely, the Internet has become the backbone of our society. It's incredible how commonplace has everything related to the Internet has become. We assume everyone knows how to access any website, or even stream video.

Technology is like magic nowadays. Just see how crazy it is that I can call someone on the other side of the world at any time only using a device that fits in my pocket and have instantaneous communication. Way better than magic in some books.

Concerning that, I wanted to share with you the following article on the History of the URL shared on Cloudflare's blog. It goes from the birth of network communications to current day Web applications. I see it as a nice summary of the history of the Internet, not just as the title implies, the URL.

Have a look and let me know if you like it.

I haven't made a post in a while, but finally this week I'm back with a new blogpost!

The blog post goes into the details of how to scan a process' memory using LLDB (Which also generated a fun debate at home on the proper use of apostrophes). Useful when trying to extract information from a process memory when doing some security testing or reverse engineering. If you are interested here is the link:

As always, feedback is welcomed.

Alright, that's it for this edition of the newsletter. Until next time, keep yourself safe, and remember to be kind to others. Some people are having a hard time. Let's do our part to make things better.
