MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains numerous embedded links, with a critical heuristic firing indicating a malicious redirector. The primary malicious URL identified is 'https://ttraff.me/wix?keyword=effect+of+temperature+on+amylase+activity+method', which is likely used to redirect users to a malicious site. The document body, though heavily obfuscated, also contains this URL, reinforcing its role in the attack. The presence of a large number of links hosted on cdn.shopify.com suggests an attempt at SEO poisoning to drive traffic to the malicious redirector.

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.
-
