    [+] Summary    : This Metasploit auxiliary module generates a crafted .cif file designed to test for memory corruption conditions in Open Babel 3.1.1. By providing an excessive number of symmetry operations, it triggers a crash (DoS) during file parsing. 
                     The exact outcome depends on the target’s build, compiler settings, and memory allocator. The module includes configurable parameters for file name and iteration count, with safe upper limits to prevent framework instability.
