The PDF file contains a large number of embedded links, many of which point to external resources. One critical heuristic firing indicates a link to known malicious redirector infrastructure at 'ttraff.cc'. The document body, though heavily obfuscated, contains text related to 'Quittung vorlage privat pdf', suggesting a lure for users seeking a private receipt template. The presence of numerous Shopify-hosted PDF links, while many are confirmed benign, suggests a link farm or SEO poisoning tactic to distribute the malicious payload. The primary malicious IOC is the redirector 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.
-
