MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a lure related to 'Logo quiz level 7 answers by bubble' and embeds multiple links. One critical heuristic indicates a malicious redirector link pointing to 'https://ttraff.link/wix?keyword=logo+quiz+level+7+answers+by+bubble'. Another heuristic flags the document as a PDF link farm, containing numerous external links, with the first being 'https://cdn.shopify.com/s/files/1/0431/6676/1120/files/parezebotivesufa.pdf'. The presence of these links and the redirector strongly suggests a phishing or malicious redirection attempt.

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.
