T1566.002 Spearphishing Attachment T1204.002 Malicious Link T1059.001 PowerShell

The PDF document contains a lure related to a 'Community support program individual plan template' and embeds multiple links. One critical heuristic indicates a malicious redirector link to 'ttraff.com', which is likely used to deliver a second-stage payload. The document also contains a high-risk heuristic for a remote-support tool lure, suggesting the user might be prompted to install such software. The presence of numerous embedded links, including a link farm on Shopify, further supports a malicious intent to redirect users to potentially harmful sites.

Heuristics 4

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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.
  • Remote-support tool lure high SE_REMOTE_SUPPORT_LURE
    Document instructs the user to install, open, or connect with a remote-support tool such as AnyDesk, TeamViewer, Quick Assist, or ScreenConnect — high-risk in an unsolicited document
  • 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.
