MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.001 Malicious Link

The PDF file contains a critical heuristic firing indicating a malicious redirector link. The document body, though heavily obfuscated, contains the same URL. This URL is likely used to redirect the user to a phishing or malware distribution site. The presence of a callback lure heuristic suggests a potential social engineering tactic to trick the user into interacting further.

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.
  • 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.
