T1566.002 Spearphishing Attachment
T1204.001 Malicious Link
T1059.001 PowerShell
The PDF contains a malicious redirector link disguised as a 'Cardiovascular examination pdf'. The link points to 'https://ttraff.cc/wb?keyword=cardiovascular%20examination%20pdf', which is a known malicious redirector. The document also contains a large number of links to a PDF link farm hosted on cdn.shopify.com, likely for SEO poisoning or to obscure the malicious redirector. No scripts were extracted, but the presence of a malicious redirector and the lure suggest a phishing or credential harvesting attempt.
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.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
