MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains numerous embedded links, with a critical heuristic firing indicating a link to known malicious redirector infrastructure at 'https://ttraff.com/wb?keyword=berberina%20lemma%20pdf'. Another critical heuristic identified a large number of external PDF links, suggesting a link farm for SEO manipulation or to obscure the true malicious destination. The document body, though heavily obfuscated, also contains URLs pointing to Shopify and other domains, some of which are marked as benign while others are unknown. The primary attack pattern involves redirecting users to potentially harmful sites.
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.
-
Embedded URL info EMBEDDED_URLOne 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.URL https://ttraff.com/wb?keyword=berberina%20lemma%20pdf
