Malware Insights
The PDF document contains a heuristic firing for a malicious redirector link and a PDF link farm, indicating an attempt to lead the user to malicious infrastructure. The document body, though heavily obfuscated, contains a URL that matches the redirector link found in the heuristics. The presence of numerous embedded links to external PDFs further supports the attack pattern of a link farm designed to obscure the ultimate destination or to distribute malicious content. The heuristic 'SE_CALLBACK_LURE' suggests a potential social engineering pretext for the user to interact with the document's links.
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.club/wix?keyword=ambulance+mp4+song
