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

The PDF document contains a large number of external links, many of which are numerically or generically named, suggesting a link farm designed to attract traffic. One prominent link, "http://mindforyou.org/uploads/1/3/0/3/130313228/130313228.html#como+descargar+pokemon+negro+2+para+pc+sin+emulador", is presented as a guide to download a game, likely a social engineering lure. The presence of numerous PDF files hosted on various domains further supports the link farm tactic.

Heuristics 3
