T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to `https://ttraff.ru/pify?keyword=bohat%25C3%25BD+t%25C3%25A1ta+chud%25C3%25BD+t%25C3%25A1ta+pdf+download`. It also exhibits characteristics of a PDF link farm, with numerous embedded URLs, many pointing to Shopify domains. The document body text, though garbled, includes the same malicious redirector URL and a benign Shopify URL, suggesting a lure to disguise the malicious link. The primary intent appears to be redirecting users to malicious infrastructure, likely for further exploitation or phishing.
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=bohat%25C3%25BD+t%25C3%25A1ta+chud%25C3%25BD+t%25C3%25A1ta+pdf+download
