MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.me/wix?keyword=eureka+math+lesson+7+homework+answer+key'. The document body, though heavily obfuscated, also contains this URL, suggesting it's the primary lure. The PDF also exhibits characteristics of a link farm, with numerous embedded URLs, many pointing to Shopify and static.usrfiles.com, likely for SEO manipulation to increase visibility of the malicious link. No scripts were extracted, and the PDF structure itself does not indicate exploitation, thus the attack pattern is focused on social engineering via a malicious link.

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.
