T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains a large number of embedded links, many pointing to external PDF files, which is indicative of a link farm or SEO spamming technique. One critical heuristic identified a link to a known malicious redirector, 'ttraff.ru', which is used to obscure the final destination. The document body, though heavily obfuscated, contains text related to academic marksheets and the malicious URL, suggesting a lure to trick users into clicking the link. No scripts were extracted, but the primary attack pattern involves redirecting users to malicious infrastructure.
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.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://ttraff.ru/pify?keyword=self+attested+certificate+of+pervious+academic+marksheet+pdf
