Rockstar🎓
Top SchoolLev Aronsky is a Lead Security Researcher with 11 years of hands-on experience in reverse engineering, vulnerability discovery, and building security tooling from concept to production. Based in Givatayim, Israel, he has led teams at HCL Technologies to modernize core products, add iOS kernel KVM support for emulation, and uncover a cross-platform Microsoft Word vulnerability (CVE-2021-36941). Equally comfortable in Python and C, Lev has contributed to prominent open-source projects like radare2 and low-level QEMU tooling, demonstrating expertise in ESIL, guest services, and embedded architectures. He combines deep systems-level research—reverse engineering obscure SoCs and building hypervisors—with practical product delivery, such as a language-agnostic source code analysis IR and supply-chain inspection tooling. Known as a fast learner and versatile collaborator, he bridges offensive research and engineering to turn security insights into robust, deployable solutions.
