The PDF contains a malicious redirector link that leads to a URL designed to lure users into clicking it, likely for credential harvesting or malware delivery. The document body, though heavily obfuscated, contains text related to 'Ibps rrb notification 2020 pdf freejobalert', suggesting a lure for job seekers. The presence of numerous external PDF links, many pointing to Shopify, indicates a link farm strategy to improve SEO and distribute malicious content. The heuristic 'SE_CALLBACK_LURE' further suggests a phishing or scam pretext.

Heuristics 4

  • 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.
  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns
  • 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.
