MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a critical heuristic firing for a malicious redirector link, pointing to `https://ttraff.cc/pify?keyword=blessings+and+curses+derek+prince+free+download`. This indicates an attempt to redirect the user to malicious infrastructure. Additionally, the PDF exhibits characteristics of a link farm, embedding numerous external links, many hosted on Shopify, suggesting a tactic to artificially inflate search engine rankings or distribute content. The document body, though heavily obfuscated, contains the primary malicious URL and other embedded URLs, reinforcing the lure for free downloads.

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.
