PROFILE

Jörg Stucke

Contributed to the onekey-sec/unblob repository by developing six new extraction and analysis features over three months, focusing on expanding support for diverse archive and filesystem formats found in embedded firmware. Work included implementing handlers and extractors for DEAFBEAD archives, MINIX filesystems, Broadcom SquashFS v4, encrypted Alpha Networks D-Link firmware, FPKG/CPKG firewall archives, and Moxa FRM containers. Each feature was delivered with comprehensive Python-based tests and detailed documentation, ensuring reliability and ease of integration. The approach emphasized robust backend development, cryptography, and data extraction, enabling automated processing of complex firmware images and reducing manual analysis for enterprise and research users.
