T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains numerous links, with a primary link identified as a malicious redirector. The document body and heuristics indicate an impersonation of a document signing service (like Adobe Sign or DocuSign) to trick users into clicking the malicious link. The primary malicious URL is 'https://ttraff.com/pify?keyword=sign+adobe+pdf+on+iphone', which likely leads to further malicious content or phishing pages.
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.
