T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a link that redirects to a malicious domain, disguised as an 'Assam tet 2020 syllabus pdf lp'. This is a common lure to trick users into visiting a potentially harmful website. The file also contains a large number of external PDF links, many hosted on Shopify, suggesting a link farm or SEO poisoning tactic to increase visibility of the malicious redirector.
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.
