MITRE ATT&CK
T1059.001 PowerShell
The file is a malicious OLE document exhibiting a large slack space anomaly, suggesting hidden or packed content. The PEB access heuristic indicates potential anti-analysis or evasion techniques. While no explicit script was extracted, the document structure and heuristics suggest it's designed to exploit a vulnerability, likely to download and execute a second-stage payload. The SHA256 hash is included as a primary IOC.
Heuristics 2
-
PEB access via FS segment (x86) high SC_PEB_ACCESSPEB access via FS segment (x86)
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 130,112 bytes but its declared streams total only 16,486 bytes — 113,626 bytes (87%) live in unallocated sector slack. This is the canonical hiding place for pre-macro-era Office exploit payloads (XOR-encoded shellcode reached via a parser pointer-corruption bug in the document structure).
