T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a mass external link farm, with many links pointing to Shopify-hosted PDFs, likely as a SEO-based lure. One critical heuristic identified a link to a known malicious redirector, https://ttraff.link/wix?keyword=acma+study+guide+login, which is the primary IOC. The document body, though heavily obfuscated, contains this URL and references 'acma study guide login', suggesting a phishing or credential harvesting pretext. No scripts were extracted from this sample.

Heuristics 3
-
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.
-
