What it detects

This rule detects execution of the legitimate Tablacus Explorer binary from a ProgramData subdirectory where a malicious DLL is side-loaded through search-order hijacking. This technique is used in the APT Meets GPT campaign to run GOVERSHELL under the cover of a signed file-manager application. Abusing a trusted binary from an unusual path lets attackers evade application controls and blend into normal host activity.
