MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious Link

This PDF document contains a high number of embedded links, many pointing to Shopify domains, but also includes a critical link to a known malicious redirector at 'ttraff.ru'. The document body, though heavily obfuscated, contains the same malicious URL and mentions 'wkhtmltopdf', suggesting it was generated by a tool. The presence of a remote support lure heuristic indicates the document may instruct users to install or connect to such tools, a common tactic for gaining unauthorized access. The SE_LOLBIN_RUN_COMMAND heuristic further suggests the potential for executing commands on the user's system.

Heuristics 5

  • 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.
  • Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMAND
    Document contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
  • Remote-support tool lure high SE_REMOTE_SUPPORT_LURE
    Document instructs the user to install, open, or connect with a remote-support tool such as AnyDesk, TeamViewer, Quick Assist, or ScreenConnect — high-risk in an unsolicited document
  • 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.
