What it detects

This rule detects process execution referencing a RECYCLERS.BIN directory, a masquerade of the Windows Recycle Bin used as a hidden staging location in the DLL side-loading campaign to run tmp.bat. Executing scripts from a directory imitating the Recycle Bin is a defense-evasion and staging indicator.
