T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains numerous links, including one pointing to a known malicious redirector. The document body, though malformed, contains text suggesting it is an 'answer key' lure. The primary malicious link identified is https://ttraff.ru/pify?keyword=mcgraw+hill+answer+key+algebra+1, which is likely used to redirect the user to further malicious content. The presence of a link farm heuristic further supports 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.
