MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a link to a known malicious redirector, indicating an attempt to lead the user to a harmful destination. The document body, though heavily obfuscated, includes the same URL, reinforcing the malicious intent. No scripts were extracted, but the presence of the malicious URL is sufficient to classify this as a phishing or redirection attempt.

Heuristics 2

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.
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.
