The source examines the macOS port of the DPRK-linked Dacls/MATA malware family and explains how to build YARA rules from non-Objective-C binary traits. The analysis focuses on exported MataNet function names, wolfSSL-linked symbols, HTTP header strings, plist persistence paths, RC4 routines, and reverse-shell/networking functions visible in the sample. It treats those strings and symbols as higher-value signature material for detecting MATA components, while pointing readers to protocol-emulation research for deeper C2 discovery. The report is useful for Lazarus/DPRK tracking because it documents practical macOS malware detection logic rather than a new intrusion campaign.
