Malware Insights
The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'ttraff.ru'. This URL is presented as a download for an 'excel calculation sheet template', a common lure. The document also exhibits a PDF link farm heuristic, indicating a large number of external links, many of which are hosted on Shopify but some point to potentially malicious domains. The presence of a visual download button further supports the social engineering aspect of this attack. No scripts were extracted, but the primary attack vector appears to be a malicious redirector disguised as a document template.
Heuristics 4
-
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.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
