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

The PDF file contains a deceptive document body that mimics search results for 'Bombay movie songs free telugu'. It embeds multiple links, with a critical heuristic identifying a malicious redirector at 'https://ttraff.com/pify?keyword=bombay+movie+songs+free++telugu'. Another heuristic indicates a link farm, with 'https://cdn.shopify.com/s/files/1/0430/1655/2605/files/rezaredajap.pdf' being the first identified URL in this farm. The primary intent appears to be directing users to malicious infrastructure through social engineering.

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.
