Prior to that she held senior positions at AWS and Intel, and different roles in the threat detection industry, as a malware reverse engineer and incident responder. Marschalek is a frequent speaker at major security conferences, including Black Hat, Defcon, HITB, RSA, and SyScan, among others. She used to teach reverse engineering classes at University of Applied Sciences St. Poelten, from where she graduated in 2011 with a Master’s Degree in Information Security. In 2015 she started a hacker bootcamp for women titled BlackHoodie, which over the years established itself as a global initiative to attract more diverse talent to the security industry. In her spare time she enjoys long distance running.

Aaron Portnoy is Chief Product Officer at Mindgard and the inaugural Hacker Fellow at Dartmouth College, applying over twenty years of offensive research to AI security. He created the Pwn2Own hacking competition, organizing and judging its first six iterations while running research at TippingPoint's Zero Day Initiative, and went on to co-found Exodus Intelligence, one of the first firms to commercialize zero-day research. Over his career he has personally discovered hundreds of zero-day vulnerabilities in software from vendors including OpenAI, Cursor, NVIDIA, Microsoft, Google, Amazon, Palo Alto Networks, and Adobe; authored the award-winning IDA Toolbag; and published research in Phrack. He has led offensive programs at Raytheon and Boldend and pioneered attack surface management research at Randori through its IBM acquisition. His current research focuses on the security of AI systems. Featured in TIME Magazine's 2014 cover story "World War Zero," Aaron has delivered over thirty invited talks at venues including Black Hat, REcon, CanSecWest, EkoParty, USENIX WOOT, BlueHat, RSA, and the NSA Distinguished Speaker Series.
