MITRE ATT&CK
T1204 Malicious File T1059 Command and Scripting Interpreter T1027 Obfuscated Files or Information

The sample is identified as malicious by ClamAV and exhibits critical heuristic firings indicating exploit activity (CVE-2006-3590) and XOR-encoded strings. The presence of LoadLibrary and GetProcAddress API references suggests dynamic loading of further malicious code. Although VBA macros could not be extracted, the core exploit mechanism is clearly identified.

Heuristics 9

  • CVE-2006-3590 — PowerPoint malformed shape-container payload critical CVE likely CVE_2006_3590
    PowerPoint Pictures stream begins with malformed shape-container material and carries embedded resolver shellcode or a PE-like payload. This matches the MS06-048 mso.dll PowerPoint exploit family tracked as CVE-2006-3590.
  • XOR-encoded strings (key 0x5D) critical SC_XOR_ENCODED
    Found 4 Windows library/API name(s) XOR-encoded with single-byte key 0x5D: 'KERNEL32.DLL', 'LoadLibraryA', 'GetProcAddress', 'InternetOpenA'
  • ClamAV: Win.Trojan.Exploit-110 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Exploit-110
  • x86 GetPC stub (CALL $+5; POP EAX) high SC_GETPC_CALL
    x86 GetPC stub (CALL $+5; POP EAX)
  • PEB access via FS segment (x86) high SC_PEB_ACCESS
    PEB access via FS segment (x86)
  • PEB API-hash resolver high SC_API_HASH_RESOLVER
    PEB access followed by ROR13-style API hashing, a common position-independent shellcode import resolver
  • Reference to LoadLibrary API high SC_STR_LOADLIBRARY
    Reference to LoadLibrary API
  • Reference to GetProcAddress API high SC_STR_GETPROCADDRESS
    Reference to GetProcAddress API
  • Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTED
    olevba could not extract VBA macros (PermissionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
