T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF document contains a mass of external links, including a critical link to a known malicious redirector at 'https://ttraff.ru/pify?keyword=cbt+worksheet+for+anxiety+pdf'. The document body, though heavily obfuscated, contains text suggesting it is a 'CBT worksheet for anxiety pdf', likely a lure to encourage clicks on the malicious link. The presence of numerous Shopify-hosted PDF links suggests a link farm for SEO poisoning or traffic generation to the primary malicious URL.
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.
