MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains an embedded URL that points to a suspicious domain, likely intended to deceive the user into clicking it. The heuristic 'SE_LOLBIN_RUN_COMMAND' suggests the document text may contain command-like strings, further indicating a malicious intent to execute or prompt user interaction with system commands. No scripts were extracted, but the presence of the external URI and command-like text strongly suggests a phishing or credential harvesting attempt.

Heuristics 3

  • LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMAND
    Extracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
