T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF contains multiple embedded links, with one heuristic specifically identifying a malicious redirector link to 'ttraff.ru'. Another heuristic indicates a link farm hosted on 'static.usrfiles.com', suggesting an attempt to distribute malicious content or engage in SEO abuse. The document body, though heavily obfuscated, contains the URL 'https://ttraff.ru/wix?keyword=handwritten+thank+you+note+after+interview+template', reinforcing the malicious redirector finding. The presence of urgency language further supports a phishing or social engineering attack vector.
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/wix?keyword=handwritten+thank+you+note+after+interview+template
