T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains a link to a known malicious redirector, ttraff.ru, which is disguised as a link to a book about Microsoft Azure administration. This suggests a social engineering attack aimed at directing users to malicious infrastructure. The file also contains a large number of links to other PDFs, indicating a link farm strategy, likely for SEO poisoning or to obscure the malicious redirector. No scripts were extracted, but the presence of a malicious redirector and the lure content strongly indicate a phishing or malware distribution attempt.

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.
-
