MITRE ATT&CK
T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The PDF file contains heuristics indicating it is related to CVE-2023-26369, a vulnerability often exploited to execute arbitrary code. The presence of external URIs and embedded streams further suggests the file is designed to download and execute a secondary payload. The document body is heavily obfuscated and unreadable, providing no further context on its specific lure.

Heuristics 4

  • TrueType bitmap font + active content — CVE-2023-26369 related info CVE related PDF_CVE_2023_26369_RELATED
    PDF embeds a TrueType font with bitmap tables (EBDT/sbix/CBDT) alongside exploit delivery indicators — CVE-2023-26369 exploits the sfac_GetSbitBitmap function in Adobe's libCoolType for arbitrary code execution. This CVE was actively exploited in the wild, but this rule does not validate the malformed EBLC/EBDT primitive.
  • External URI info PDF_URI
    PDF contains an external URL action
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • 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.

Detection
ClamAV: No threats found
Obfuscation or payload: likely
31 of 45 identifiers look randomly generated (e.g. 'FKUcOYeOYeOYeOYeOYeOYeOYeOYfOYfOYfOYfOYf') — consistent with name-mangling obfuscation. Carved artifact contains 305 long base64-like blob(s).
