Rockstar🎓
Top SchoolNikias Bassen is a veteran mobile security engineer and product security leader with 17 years of hands-on experience building and hardening tooling for iOS devices. As VP of Product Security at Zimperium and former platform/security lead roles (including at Corellium), he blends deep reverse-engineering skills with product-focused security strategy. He is a prolific open-source contributor to the libimobiledevice ecosystem—authoring robust backend improvements to usbmuxd, libirecovery, libplist and related tools that power cross-platform iOS device communication. His work on OSS-Fuzz for libplist and numerous fixes to pairing, AFC and DFU flows shows a rare combination of fuzzing-driven vulnerability discovery and pragmatic protocol engineering. Based in the Greater Hamburg Area, he runs samara IT and brings founder-level systems design and long-term maintenance sensibility to security productization. Notably, his contributions often sit at the intersection of low-level USB/firmware protocols and secure product workflows, making him an expert at turning exploit knowledge into defensible platforms.
