MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
T1059.001 PowerShell
The PDF file contains numerous embedded links, a technique often used to redirect users to malicious websites. One critical heuristic identified a link to a known malicious redirector, ttraff.com, which is part of a link farm designed to obscure the final destination. The document body, though heavily obfuscated, suggests a lure related to a 'scholarship acceptance letter'. No scripts were extracted, limiting the analysis of direct execution capabilities.
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.com/pify?keyword=scholarship+acceptance+letter+sample+pdf
