T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a prominent link that redirects to a malicious domain, masquerading as a Facebook Messenger app update. This is further supported by the PDF_MALICIOUS_REDIRECTOR_LINK heuristic firing. The document also exhibits characteristics of a link farm, with numerous embedded URLs pointing to various PDF files, likely for SEO manipulation or to host further malicious content. The primary malicious IOC is the redirector URL.
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.
