What it detects

This rule detects creation of the human2.aspx web shell dropped into the MOVEit Transfer wwwroot after exploitation of the CVE-2023-34362 SQL injection chain. This artifact gives the attacker web-accessible command and data-theft capability on the MOVEit host and its presence is a reliable sign of active exploitation.
