T1566.001 Spearphishing Attachment
The PDF document contains a large number of external links, many of which advertise cracked software. One of the embedded URIs, http://xtraserp.com/jenny/classmates/ZG93bmxvYWR8dlczWVRJeWRueDhNVFkxTmpnNU1qTTFNbng4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA/addtional.ofpa..UERGIFdhdGVybWFyayBQcm8UER, appears to be a lure for downloading potentially malicious files. The presence of a link farm and cracked software lures suggests a malicious intent to trick users into downloading malware.

Heuristics 4
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
PDF link farm advertises cracked/pirated software medium PDF_CRACKED_SOFTWARE_LUREPDF contains many clickable links whose targets use cracked-software, keygen, serial-key, or warez vocabulary. These are SEO-spam lure documents that rank for software-piracy searches and route users to fake 'crack' download pages distributing potentially-unwanted programs, adware, or droppers. The PDF itself carries no exploit — the risk is the linked destinations.
