# Full Office Macro Decode Chain
> Complete pipeline: Office doc → VBA → Base64 → gunzip → XOR → shellcode

**Tools:** [[tools/oledump-py|oledump-py]], [[tools/base64dump-py|base64dump-py]], [[tools/gunzip|gunzip]], [[tools/translate-py|translate-py]], [[tools/scdbgc|scdbgc]]
**FOR610 Lab:** 3.4

## Commands
```bash
# Step 1: List streams and extract VBA
oledump.py <document>
oledump.py <document> -s <macro_stream> -v
# Step 2: Extract Base64 from data stream
oledump.py <document> -s <data_stream> -d | base64dump.py -s 1 -d > stage1.ps1
# Step 3: Decode second Base64 layer + decompress
base64dump.py stage1.ps1 -s 3 -d | gunzip > stage2.ps1
# Step 4: XOR decode the shellcode
base64dump.py stage2.ps1 -s 2 -d | translate.py 'byte ^ 35' > shellcode.bin
# Step 5: Emulate the shellcode
scdbgc /f shellcode.bin /s -1
