Malware Insights
The PDF file contains a critical heuristic firing for a malicious redirector link pointing to 'https://ttraff.ru/pify?keyword=dd-+214+blanket'. Additionally, it exhibits a PDF link farm pattern with 16 external PDF links, many hosted on Shopify domains, with the first identified as 'https://cdn.shopify.com/s/files/1/0436/1607/5939/files/kofexanebalinakunisam.pdf'. The document body, though heavily obfuscated, contains the same malicious URL and a benign-looking PDF filename, suggesting a lure to click on the malicious link. The 'SE_URGENCY_LURE' heuristic further supports the social engineering aspect.
Heuristics 4
-
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.
-
Urgency / deadline lure low SE_URGENCY_LUREDocument contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
-
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=dd-+214+blanket
