T1204.001 User Execution: Malicious Link
T1059.001 PowerShell
The PDF contains a link that redirects to a known malicious domain, identified by the PDF_MALICIOUS_REDIRECTOR_LINK heuristic. The PDF also contains a large number of external links, suggesting a link farm for SEO manipulation, as indicated by the PDF_SEO_LINK_FARM heuristic. The embedded URL points to a redirector that ultimately leads to a page related to 'mitosis and meiosis amoeba sisters worksheet', likely a lure to entice clicks. The SE_DOWNLOAD_BUTTON heuristic further supports the idea of a deceptive call-to-action.
Heuristics 4
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF 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_FARMSmall 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.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
