T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF contains multiple embedded links, with a critical heuristic firing for a malicious redirector. The primary malicious URL is 'https://ttraff.ru/pify?keyword=bondhurey+by+siam+video+song', which is likely used to redirect users to a malicious site. The document body is heavily obfuscated and contains metadata suggesting it was generated by wkhtmltopdf, a tool often abused for creating malicious PDFs. The presence of numerous external PDF links also indicates a link farm, a common tactic for SEO poisoning or distributing malware.

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.
