MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file exhibits malicious behavior through a high density of embedded external links, identified as a 'PDF SEO Link Farm'. One critical heuristic indicates these links lead to a known malicious redirector infrastructure. The document body contains text related to 'Qms clauses pdf' and mentions the authoring application 'wkhtmltopdf', suggesting a lure document. The primary attack pattern involves redirecting users through a chain of links, with the initial redirector pointing to a URL associated with malicious activity.
Heuristics 3
-
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.
