T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document is identified as malicious due to its structure, which includes a large number of external links, many pointing to Shopify domains. The primary malicious link, https://ttraff.ru/wb?keyword=cambridge%20igcse%20geography%20revision%20guide%20student's%20book%20pdf, acts as a redirector, likely leading to further malicious content. The document body, though heavily obfuscated, contains keywords related to educational materials, suggesting a lure to disguise the malicious intent.

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.
