OLE_SLACK_XOR_SCRIPT_CONFIG
What it means
Unallocated OLE bytes decode to a CScript command, JavaScript filename, and multiple URLs.
Why it fires
This rule handles exploit-era OLE documents whose XOR-hidden region contains a launch configuration rather than a complete script. Candidate keys must reveal the exact CScript /nologo command form, a JavaScript filename, at least two syntactically valid absolute URLs, and a mostly textual decoded region. The URLs retain their XOR provenance and the decoded configuration is carved for authenticated review.
