What it detects

This rule detects Microsoft Equation Editor (EQNEDT32.EXE) spawning a child process. LokiBot delivery chains weaponize CVE-2017-11882 and CVE-2017-0199 in RTF documents so that the outdated equation editor executes attacker code, an event with no legitimate cause on modern systems.
