MITRE ATT&CK
T1059.001 PowerShell

The PDF contains a large number of embedded URLs pointing to other PDF files across various domains, indicative of a link farm or distribution network. The 'SE_LOLBIN_RUN_COMMAND' heuristic suggests that the document may contain instructions for executing commands, potentially leveraging tools like PowerShell to interact with these links or download further payloads. ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a malicious classification.

  • ClamAV: Pdf.Phishing.TtraffRobotInstall-7605656-0 critical CLAMAV_DETECTION

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMAND
    Extracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.
  • 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.
