MITRE ATT&CK
T1059.001 PowerShell
T1566.002 Spearphishing Attachment
The PDF document contains a fake CAPTCHA prompt to lure the user into clicking a link. The primary malicious link identified is https://ttraff.com/pify?keyword=va+form+21-+8416, which is a known malicious redirector. The document also hosts a large number of other PDF files on Shopify domains, likely as part of an SEO link farm to obscure the malicious activity. No scripts were extracted, but the presence of a malicious redirector and the fake CAPTCHA strongly indicate a phishing or scam 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.
