MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains heuristics indicating it advertises cracked software and embeds external URIs. The primary malicious URL, http://find24hs.com/asks/applicator.grillparzer?SGVyIHBhIGJlcmdldC4gVGVrc3Rib2sucGRmSGV=degustation.easier&famiy=grid.ZG93bmxvYWR8Z3A5TTJ0eWIzeDhNVFkxTnpBMk56RTFOSHg4TWpVNE4zeDhLRTBwSUVobGNtOXJkU0JiUm1GemRDQkhSVTVk, likely serves as a downloader for a second-stage payload. The presence of 'cmdldC4gVGVrc3Rib2sucGRmSGV=degustation.easier&famiy=grid.ZG' in the document text suggests the use of command-line execution, potentially via embedded scripts.

Heuristics 4

  • 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.
  • PDF link farm advertises cracked/pirated software medium PDF_CRACKED_SOFTWARE_LURE
    PDF contains many clickable links whose targets use cracked-software, keygen, serial-key, or warez vocabulary. These are SEO-spam lure documents that rank for software-piracy searches and route users to fake 'crack' download pages distributing potentially-unwanted programs, adware, or droppers. The PDF itself carries no exploit — the risk is the linked destinations.
  • 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.
