MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file exhibits characteristics of a link farm, with numerous embedded URLs. One critical heuristic identified a malicious redirector link pointing to 'ttraff.ru', which is likely used to obscure the final destination or host malicious content. The document body, though heavily obfuscated, contains references to 'Fate grand order farming guide' and the redirector URL, suggesting a lure. The presence of a large number of external PDF links, many hosted on Shopify, further supports the SEO manipulation or content hosting aspect of the attack.
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.
