Behind the Attack: Juliana Testa

The ATT&CK Evaluations (Evals) team are a group of dedicated cybersecurity professionals with multiple decades of combined experience. Get to know Juliana Testa, an Execution Coordinator & Threat Hunter on the Evals Execution team and one of the minds behind executing emulations.

What is your role on the team?

As a member of the Execution Team, I coordinate with participants to ensure a seamless evaluation process. I am trained on their threat hunting platforms and collaborate with our Red Team Operators to identify indicators of compromise (IOCs) corresponding to the tactics, techniques, and procedures (TTPs) of the developed scenarios and malware.

What’s an interesting trend in Cybersecurity?

I find random number generation (RNG) in cybersecurity and cryptography to be absolutely fascinating. If you haven’t looked into it, I highly recommend it. The process of creating truly random numbers for cryptography involves using unreproducible phenomena as seeds, like atmospheric noise, hardware entropy, or, in the case of Cloudflare, lava lamps. Random seed production is an critical part of sustaining strong encryption and it requires us to take a step past statistically random and into the realm of wholly unpredictable.

When I’m not diving into malware or teaching about SIEMs, you can catch me competing in sailing championships both nationally and internationally.
