T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a mass of external links, identified as a PDF SEO link farm. One of these links, 'https://ttraff.cc/wix?keyword=hadoop+the+definitive+guide+filetype+pdf', points to known malicious redirector infrastructure. The document body, though heavily obfuscated, contains this malicious URL and numerous other benign-looking PDF links, suggesting an attempt to manipulate search engine results or trick users into navigating to malicious sites.
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.
