About
👋 Hi, I’m Joe Lopes
I’m an Information Security Engineer focused on threat detection, SIEM, logs, and adversary engagement. My work lives at the intersection of systems, data, and behavior: observing signals, correlating events, and extracting meaning from noise.
I’m Brazilian (Portuguese is my native language) and my given name is José (pronounced djo-zeh). In English it’s often mispronounced ho-zay, which is the Spanish form. Since José maps naturally to Joseph, I go by Joe: it’s simpler, clearer, and travels better.
This site, lopes.log, is my working notebook: a place where I document investigations, ideas, tools, and the occasional lesson learned the hard way.
There are no ads ⛔ here. Just long-form thinking, written slowly and published with intent.

🦫 Vigil

Vigil is the beaver of lopes.log, and in many ways, my mirror.
Vigil is not cute, not angry, not heroic. Vigil is focused, neutral, and intelligent.
Like an engineer, Vigil works quietly: observing flows, reading structures, building meaning from fragments. Where others see raw logs, Vigil sees structures.
Vigil represents the way I approach security and systems: with patience, precision, and respect for complexity.
At lopes.log, I work with Vigil. Where others see logs, we see stories.
