MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The file is identified as malicious by ClamAV with the signature Doc.Trojan.WhiteIce-1. Static analysis detected a critical heuristic firing for VBA p-code auto-execution with execution tokens, specifically using the 'Shell' command, and a high severity heuristic for a heap-spray pattern. Although the VBA project contains no executable statements, the auto-execution mechanism suggests an attempt to leverage a vulnerability. No specific IOCs were extracted.

Heuristics 5

ClamAV: Doc.Trojan.WhiteIce-1 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Trojan.WhiteIce-1
Heap-spray pattern detected high SC_HEAP_SPRAY

Repeated 0x41 (A) bytes found
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
Suspicious extracted artifact high 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.
VBA project contains no executable statements low OLE_VBA_MACROS

Document contains a VBA project, but extracted modules only contain attributes/options/comments and no executable statements.

Extracted artifacts 1
