MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF contains numerous heuristics indicating it is part of a link farm advertising cracked software, a common lure for malware distribution. One embedded URI, http://evacdir.com/TmV0IFNoaW1tZXITmV/decreasage.middled/hibiscus.mikhailovich/?ZG93bmxvYWR8SXo3TWpaaGJIeDhNVFkxTkRZME16TTFNSHg4TWpVNE4zeDhLRTBwSUVobGNtOXJkU0JiUm1GemRDQkhSVTVk=kwai, is highly suspicious and likely serves as a download or redirection point for a second-stage payload. The PDF structure itself, with its extensive external links, suggests an attempt to host malicious content or redirect users to phishing sites.

Heuristics 4

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

Small 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_LURE

PDF 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.
External URI info PDF_URI

PDF contains an external URL action
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
