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

The PDF file exhibits characteristics of a phishing lure, including a small file size and a single image designed to mask a clickable link. The embedded URL, https://cloud-direct.biz/doc0047581678.pdf, is the primary indicator of malicious intent, likely serving as a redirection to a phishing site or a download of further malware. ClamAV also detected this file as Pdf.Dropper.Agent-7133505-0, reinforcing its malicious nature.

Heuristics 5

  • Malformed JPEG2000/JP2 box structure high CVE related PDF_JP2_BOX_ANOMALY
    PDF embeds JPEG2000/JP2 data with malformed box sizes. This is a parser-exploit indicator for JPX/JPEG2000 CVE families, not a unique CVE fingerprint.
  • ClamAV: Pdf.Dropper.Agent-7133505-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Dropper.Agent-7133505-0
  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 1 image(s), only 1 text block(s), carries a click-outward action, and is only 17 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • 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.
