MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains embedded text that mimics a "Weed eater 500 series lawn mower manual", suggesting a social engineering lure. The presence of an external URI pointing to "fokemale.ru" further supports the malicious intent, likely to redirect the user to a phishing or malware download site. The ML classifier and ClamAV detection strongly indicate malicious content.

  • 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.
