T1566.002 Spearphishing Attachment
T1204.002 User Execution: Malicious Link
The PDF file contains numerous embedded links, with a critical heuristic identifying a link to a known malicious redirector at 'https://ttraff.ru/pify?keyword=vestige+rice+bran+oil+pdf'. The document body, though heavily obfuscated, contains text referencing 'Vestige rice bran oil pdf', suggesting a lure to disguise the malicious intent. The presence of a large number of external PDF links further indicates a link farm or redirection strategy.
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.
