MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains numerous embedded links, identified as a link farm, with a critical heuristic firing for a malicious redirector. The primary malicious URL, 'https://ttraff.ru/pify?keyword=sparepro+catalogue+pdf', is presented as a catalogue, suggesting a lure to trick users into clicking through to potentially malicious content. The document body, though heavily obfuscated, contains references to 'sparepro catalogue pdf' and the authoring application 'wkhtmltopdf', reinforcing the lure. The presence of many Shopify-hosted PDF links, while some are marked benign, indicates a broad distribution strategy.

Heuristics 3

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF 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_FARM

Small 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.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
