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

The PDF file contains a heuristic indicating an external URI, specifically pointing to 'https://lozipotod.ru/award?keyword=different+types+of+camera+lenses+explained+pdf'. This URL, combined with the ClamAV detection and ML classifier flagging, strongly suggests a phishing or malware distribution attempt. The document body, though heavily obfuscated, appears to be a lure related to camera lenses, likely intended to trick the user into clicking the embedded malicious link.

  • 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.
