T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a link farm and a direct link to a known malicious redirector, 'https://ttraff.ru/pify?keyword=self+certified+sick+note'. This indicates a social engineering attempt to trick users into visiting a malicious site, likely for phishing or malware distribution. The document body, though heavily obfuscated, contains the same redirector URL and other URLs pointing to potentially malicious content, reinforcing the malicious intent.

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.
