T1566.002 Spearphishing Attachment
T1204.002 User Execution: Malicious Link
The PDF file contains a heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK, indicating it points to known malicious infrastructure. The document body explicitly mentions 'Valiant Hearts apk data' and contains a URL that redirects to 'https://ttraff.cc/pify?keyword=valiant+hearts+apk+data'. This suggests a social engineering lure to trick users into clicking the link, likely leading to malware download or a phishing page. The PDF also contains a PDF_SEO_LINK_FARM heuristic, with numerous links pointing to Shopify domains, though the primary malicious link is the 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.
-
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.cc/pify?keyword=valiant+hearts+apk+data
