MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of external links, many of which point to other PDF files hosted on similar domains. The document body text mentions 'Curriculum vitae format 2019 south africa', suggesting a lure to disguise the malicious intent. The primary attack pattern involves directing users to a network of suspicious URLs, likely for phishing or further malware delivery.

  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
