Senior🎓
Top SchoolThiago Mayllart is a Senior Red Team Engineer with a decade of hands-on experience crafting sophisticated offensive tooling and leading complex adversary simulation engagements. Based in São Paulo, he designs and automates C2 infrastructures and covert channels (creator of Harvis and DNS Profile for Mythic) while developing novel AV/EDR evasion techniques including syscall manipulation, ETW/AMSI bypasses, and custom injection loaders. He combines deep web-application and Active Directory exploitation skills with practical reconnaissance and social-engineering to build realistic phishing and persistence scenarios that minimize indicators of compromise. As a co-founder and technical lead, he has mentored teams, operationalized red-team workflows, and balanced research with client-facing reporting and remediation guidance. Proficient in Rust, C#, Python, C, Java, PowerShell and Bash, Thiago also brings academic exposure to reinforcement learning methods that inform his automated attack and decision pipelines. His public projects reveal a bias for reusable, operational tooling that bridges research and real-world engagements.
