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

The PDF file contains an embedded URL and a visual lure suggesting a download, which is consistent with a malicious dropper. The ClamAV detection of 'Pdf.Dropper.Agent-7254135-0' further supports this assessment. The document body contains numerous URLs, with the primary lure identified as a URL shortener, likely redirecting to a malicious site. No scripts were extracted from this sample.

Heuristics 5

  • ClamAV: Pdf.Dropper.Agent-7254135-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Dropper.Agent-7254135-0
  • Image-only PDF lure links through URL shortener high PDF_IMAGE_LURE_SHORTENER_LINK
    PDF is image-heavy with little real text and its clickable action points to a URL shortener. This is a high-confidence credential-phishing carrier shape: the visible page is a screenshot-like prompt while the destination is hidden behind redirect infrastructure.
  • Image-only PDF lure links to a brand-impersonating path on an unrelated host high PDF_IMAGE_LURE_BRAND_PATH_LINK
    PDF is image-heavy with little real text and its clickable action targets a URL carrying a brand name ('dropbox') as a path segment on a host that does not belong to that brand and is not known-good (e.g. 'sodecoperu.com/Docusign/index.php'). This is the credential-phishing carrier shape where a compromised or unrelated host serves a brand-named phishing kit behind a screenshot-like lure page. Distinct from the typosquat-host rule: here the host is honest-looking but the brand lives in the path.
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
