Ashkan Hosseini

I’m part of the Threat Prevention team, where I build machine learning models and advanced heuristics to block malicious traffic on the wire.

Executed web applications, Android and iOS applications, and network penetration tests. Performed both white box, source assisted code reviews, and black box security audits, and provided recommendations to address discovered security vulnerabilities.

Reverse engineered malware samples of different families to harden Endgame’s VMI sand- box platform against evasion techniques, and wrote signatures for Endgame’s internal sandbox to detect process injection and lateral movement.

Wired various program analysis and symbolic execution tools such as KLEE and JPF-SE into an automated build pipeline for vulnerability detection during compile-time.

During my time at Columbia University I researched on techniques for speeding up malware reverse engineering as well as browser security. My research allowed me to land a role at Endgame Inc.

During my time at UC Berkeley I was a full time researcher at Berkeley Usable Security (BLUES) and Secure Computing Research for Users’ Benefit (SCRUB) labs. I also served as the co-captain and lead instructor of Cybersecurity Club. My research led to multiple publications, and I co-authored two papers that got accepted to USENIX and ACM ASIACCS.
