T1059.001 PowerShell

The PDF file exhibits a critical heuristic firing for a link farm, containing 31 external PDF links, with the first being http://providence-title.com/uploads/1/3/0/3/130312998/sudorufaloleba_vudux.pdf. Additionally, a medium severity heuristic indicates a callback phishing lure, suggesting the document prompts users to call a phone number in a deceptive context. The ClamAV detection further confirms its malicious nature as Pdf.Phishing.TtraffRobotInstall-7605656-0. The embedded URLs and the nature of the heuristics strongly suggest a phishing or scam campaign.

  • 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.
  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) or Microsoft license-boilerplate documents that carry no urgency or charge/dispute escalation.
  • 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.
