MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 User Execution: Malicious Link
The PDF contains a link to a known malicious redirector, ttraff.cc, which is likely used to funnel victims to a phishing or scam page. The document body, though heavily obfuscated, contains text related to 'Optech GST software' and includes the malicious URL, suggesting a lure to trick users into clicking. The presence of numerous other links to PDF files hosted on various domains, including many benign Shopify links, indicates a link farm strategy to potentially improve search engine ranking or distribute malicious content.
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=optech+gst+software
