MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a mass of external links, many of which point to a redirector service. The primary malicious link, 'https://ttraff.ru/pify?keyword=oxford+handbook+of+clinical+pharmacology+pdf', is designed to trick users into downloading a file by impersonating a legitimate handbook. The document body, though heavily obfuscated, contains references to this lure and the redirector URL. The presence of numerous PDF links suggests a link farm or SEO poisoning tactic to distribute malicious content.
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.
-
