T1566.002 Spearphishing Attachment T1059.001 PowerShell

The document exhibits characteristics of an advance-fee scam, presenting itself as an invoice or payment instruction. It contains an embedded URL that directs the user to a potentially malicious HTML file, likely intended to further the scam. The presence of multiple similar URLs suggests a campaign distributing this lure.

Heuristics 4

  • Fake invoice / payment lure low SE_INVOICE_LURE
    Document contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
  • External URI info PDF_URI
    PDF contains an external URL action
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
  • 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.
