MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF document contains a large number of external links, a technique often used for SEO poisoning or to distribute further malicious content. One prominent URL, http://godsearchs.com/UGFyY2hlZCBmdWxsIG1vdmllIGRvd25sb2FkIGhpbmRpUGF.creamers.cornerback/elrich.ZG93bmxvYWR8MXRHWkdSNE1YeDhNVFkxTnpBMk56RTFOSHg4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA/hurtwood/huts/muttering, appears to be a direct download link. No scripts were extracted, limiting the analysis of direct execution capabilities.
