MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The file is a PDF document that contains an embedded URL pointing to a suspicious domain, identified by both heuristics and ClamAV as malicious. The document body, though heavily obfuscated, suggests a lure related to 'Basel ii document pdf', likely intended to trick users into visiting the malicious URL. No scripts were extracted, but the presence of external URIs and the ML classifier's high confidence indicate a phishing or malware distribution attempt.

  • 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.
