T1566.002 Spearphishing Attachment T1204.001 Malicious Link T1059.001 PowerShell

This PDF document contains a mass external link farm, with one critical link identified as a malicious redirector. The document body, though heavily obfuscated, contains references to 'Aircrack-ng cap file' and includes the malicious URL https://ttraff.link/pify?keyword=aircrack-+ng+cap+file. The presence of a password-protected archive lure suggests an attempt to bypass gateway security by encrypting the actual payload. The document's structure and the embedded links indicate a phishing or social engineering attack.

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.
  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE
    Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
  • 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.
    URL https://ttraff.link/pify?keyword=aircrack-+ng+cap+file
