MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a large number of external links, many of which point to benign content, but one critical link leads to a known malicious redirector. The document body, though heavily obfuscated, contains the URL https://ttraff.cc/wix?keyword=kalyani+publishers+zoology+books+pdf, which is flagged as malicious. This suggests the document is designed to trick users into clicking a link that ultimately leads to malicious infrastructure, likely for further exploitation or malware delivery.

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.
