Detects the presence of BeepRAT-related shellcode loader files (config.ini.c or temp.bin) located within a TCC (Tiny C Compiler) directory. These artifacts contain specific shellcode for hash-based API resolution, a technique used to dynamically resolve Windows API functions like LoadLibraryA and GetProcAddress to evade static analysis.
