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

The PDF file contains a large number of external links, many of which are advertised as cracked or pirated software. One of the primary links, http://sitesworlds.com/VGhlQ2hyb25pY2xlc29mTmFybmlhM2R1YWxhdWRpb2hpbmRpNzIwcAVGh/boneheaded/coves/stegosaurus?disengaging=kildow/naklua/mariposa.ZG93bmxvYWR8RXo5WXpGNk4zeDhNVFkxTnpBMk56RTFOSHg4TWpVNU9IeDhLRTBwSUVSeWRYQmhiQ0JiUm1sc1pTQlZjR3h2WVdSZA, appears to be a download URL for a malicious payload. The document body is heavily obfuscated and does not provide clear textual lures.

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.
