MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment
T1059.001 Command and Scripting Interpreter: PowerShell
The PDF contains a mass external link farm, with a critical heuristic firing for a malicious redirector link. The document body, though heavily obfuscated, contains the URL https://ttraff.cc/pify?keyword=learn+russian+language+book+pdf, which is also listed as a malicious redirector. This suggests the PDF is designed to redirect users to malicious content, likely for phishing or malware delivery. No scripts were extracted from this sample.

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=learn+russian+language+book+pdf
