Malware Insights
The PDF file contains a SE_INVOICE_LURE heuristic, indicating it is designed as a fake invoice or payment lure. It also fires a PDF_MALICIOUS_REDIRECTOR_LINK heuristic, pointing to the URL 'https://ttraff.ru/pify?keyword=microsoft+word+document+invoice+template', which is known to host malicious redirector infrastructure. Additionally, a PDF_SEO_LINK_FARM heuristic indicates a large number of external PDF links, with 'https://cdn.shopify.com/s/files/1/0431/0528/8352/files/rofupefijobojixekig.pdf' being the first identified. The document body, though heavily obfuscated, contains text related to invoice templates and URLs, reinforcing the lure tactic.
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.
