MITRE ATT&CK
T1059.003 Windows Command Shell T1204.002 Malicious Link

The PDF file contains a heuristic firing for a malicious redirector link, pointing to 'https://gettraff.ru/strik?keyword=alien+aisha+vending+machine+guide'. Additionally, a 'SE_CLIPBOARD_COMMAND_LURE' heuristic indicates the document instructs the user to execute commands via the clipboard. This suggests the document's primary purpose is to trick the user into navigating to a malicious URL, likely for further exploitation or malware delivery.

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.
  • Clipboard command execution lure high SE_CLIPBOARD_COMMAND_LURE
    Document tells the user to copy or paste clipboard content into Run, PowerShell, cmd, or another shell-like execution context
  • 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.
