T1204.002 Malicious File
T1059.001 PowerShell
The sample is a malicious OLE document exhibiting a large slack space anomaly, indicative of embedded malicious content. A high-severity heuristic firing for PEB access suggests an attempt to evade detection or manipulate process information. The document body contains VBA code that reconstructs a registry path for disabling Office features, likely to facilitate further malicious activity. This indicates an attempt to exploit a vulnerability to download and execute a second-stage 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 489,984 bytes but its declared streams total only 16,486 bytes — 473,498 bytes (97%) 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).
