T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a prominent link that, when clicked, redirects to a malicious URL identified by the 'PDF_MALICIOUS_REDIRECTOR_LINK' heuristic. The document body, though heavily obfuscated, contains text related to 'Cat 2020 question paper pdf download' and the malicious URL itself, suggesting a lure to trick users into downloading potentially harmful content. The 'PDF_SEO_LINK_FARM' heuristic indicates a large number of outbound links, further supporting 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.
