MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, many of which point to a redirector service. The primary malicious URL, https://ttraff.ru/pify?keyword=keep+bluetooth+on+airplane+mode+android, is flagged as a malicious redirector. The document body, though heavily obfuscated, contains this URL and other links to external PDFs, suggesting a link farm or redirection tactic to deliver malicious content. The file was generated using wkhtmltopdf, a tool often used to create PDF documents from web content, which aligns with the redirection strategy.
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=keep+bluetooth+on+airplane+mode+android
