Malware Insights
The PDF file contains a heuristic firing for a malicious redirector link pointing to 'https://ttraff.cc/pify?keyword=instagram+videos+private', which is presented as a lure for private Instagram videos. It also contains a large number of embedded links, many hosted on Shopify, suggesting a link farm for SEO manipulation or to obscure the final destination. The document body, though heavily obfuscated, contains the malicious URL and several benign-looking Shopify URLs, likely part of the link farm. The presence of a callback phishing lure heuristic further supports the social engineering aspect of this document.
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.
-
Callback phishing phone lure medium SE_CALLBACK_LUREDocument asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns
-
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=instagram+videos+private
