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

The PDF contains a large number of embedded links to external PDF files hosted on the domain 'ieuicufioao.myhome.cx'. This is indicative of SEO poisoning or a link farm designed to drive traffic. The heuristic 'SE_LOLBIN_RUN_COMMAND' suggests that the document may also contain instructions for executing commands via Windows scripting tools, potentially to download and execute further payloads. The document body was not readable, but the presence of numerous links and the command execution heuristic strongly suggest malicious intent.

Heuristics 3

  • 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
  • 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.
