T1203 Exploitation for Client Execution
The sample is a malicious OLE document exhibiting a large slack space anomaly and PEB access, indicative of an exploit. The document body contains obfuscated strings that, when reconstructed, reveal a registry path likely used to disable security features or manage persistence. This suggests the document is designed to exploit a vulnerability and download a secondary payload.
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 101,376 bytes but its declared streams total only 16,486 bytes — 84,890 bytes (84%) 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).
