MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link T1059.001 PowerShell

The PDF file contains a large number of embedded links, many of which point to Shopify domains, creating a link farm. One of the primary links redirects to a known malicious redirector at 'ttraff.com'. The document body, though heavily obfuscated, appears to be related to a price list, suggesting a lure to entice users to click the malicious links.

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.
