03 / talks
Information security for companies and individuals
Most incidents start with a click, a weak password or a fake message. Our talks use real examples and live demos to show how attacks happen and how to protect yourself — at work and in your personal life.
Online scams and social engineering
Phishing, hijacked WhatsApp accounts, fake tech support and tampered invoices: how to spot them before you fall for them.
Passwords and two-factor authentication
Why passwords leak, how to create strong ones and how a password manager makes it easy.
How an attacker sees your company
A live demo, in a controlled environment, of an attack from reconnaissance to access.
Data protection in practice
What personal data is, what the law (LGPD/GDPR) allows, and how to avoid common leaks.
Ransomware and backups
How data hijacking happens and how to keep the business running if it does.

05 / about
A lab, not a factory
SplinterLabs is a software house from São João del-Rei, Minas Gerais, Brazil. We treat every project like a well-run experiment: understand the problem, test hypotheses and only ship what works.
We combine two skills that rarely go together: software development and offensive security. People who know how systems are attacked build systems that are harder to attack.
