T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a lure related to 'Canadian corporate tax return forms' and includes a critical heuristic firing for a malicious redirector link pointing to 'https://ttraff.ru/pify?keyword=canadian+corporate+tax+return+forms'. Additionally, a PDF link farm heuristic indicates the document is designed to host numerous external links. The document body, though heavily obfuscated, contains the malicious URL, suggesting the primary intent is to redirect users to a potentially malicious site for phishing or other malicious activities.
Heuristics 5
-
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
-
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=canadian+corporate+tax+return+forms
