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

The PDF was flagged by multiple heuristics, including ClamAV and an ML classifier, for malicious content. The PDF_SEO_LINK_FARM heuristic indicates a large number of embedded external links, with the primary one being http://sprinkledcompany.com/uploads/1/3/0/4/130435574/dalagi.pdf. This suggests the document's primary purpose is to redirect users to malicious sites, likely for phishing or malware delivery. The document body, though heavily obfuscated, contains references to the linked URLs.

  • 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.
  • 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.
