T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a large number of embedded links, with one critical heuristic firing indicating a malicious redirector. The primary malicious URL identified is 'https://ttraff.ru/wix?keyword=strider+hiryuu+1'. The document body, though heavily obfuscated, contains references to this URL and other benign-looking URLs hosted on Shopify, suggesting a lure or distraction. The PDF structure and link farm behavior are indicative of a phishing or redirection campaign.
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.
