MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file was detected as malicious by ClamAV and an ML classifier. It contains an embedded URI that redirects to 'https://colod.co.za/XSRYdR1H?utm_term=r%C4%B1za+nur+hayat+ve+hat%C4%B1rat%C4%B1m+pdf'. This suggests the document is designed to trick users into visiting a potentially harmful website. No scripts were extracted, but the presence of external links indicates a likely 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.
