MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains numerous external links, many of which point to benign Shopify domains, but one critical link redirects through 'ttraff.cc', a known malicious redirector. The document body, though heavily obfuscated, contains the text 'name change affidavit for passport pdf' alongside the malicious URL, suggesting a lure to trick users into clicking the link. The presence of a malicious redirector indicates the intent to lead the user to a further stage of attack, likely a phishing page or malware download.

Heuristics 3

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF 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_FARM

Small 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.
Embedded URL info EMBEDDED_URL

One 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=name+change+affidavit+for+passport+pdf
