About
Trained in government. Tested in practice.
I'm Julita Rubacka, a digital forensics and evidence specialist based in Gdańsk, Poland. For three years I worked in a government digital forensics unit in Poland, acquiring and analysing evidence from mobile devices, computers and external storage.
My focus is mobile devices: from a careful acquisition to a report investigators can rely on. I hold a BEng in Computer Science and rank in the top 2% on TryHackMe.
