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

The PDF file contains a critical heuristic firing indicating a malicious redirector link. The embedded URL, https://ttraff.link/wix?keyword=aws+cloudformation+create-+stack+cli-+input-+json, is the primary indicator of malicious intent. This link likely serves as a lure to redirect users to a site designed for phishing or malware distribution. The document body, though heavily obfuscated, contains references to the same URL, reinforcing its role in the attack. No scripts were extracted from this sample.

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.
    URL https://ttraff.link/wix?keyword=aws+cloudformation+create-+stack+cli-+input-+json
