T1059.001 PowerShell
The sample is an OLE document with a large slack space anomaly, indicating potential obfuscation or embedded content. Heuristics indicate XOR-encoded strings and PEB access, suggesting malicious code execution. The document body contains text related to various application forms for permits, which is a common lure for phishing or social engineering attacks. No scripts were extracted, and the XOR key was identified as 0x97.

OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 86,016 bytes but its declared streams total only 21,308 bytes — 64,708 bytes (75%) 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).
