The threat
Attackers bury payloads inside archives, disk images, and Office files so the complete object appears only after unpacking.
How the test works
Choose a nesting pattern. Each sample hides the same test payload inside multiple container layers.
Try it yourself
✓
Test pass condition
The gateway unpacks the layers and blocks the payload.
✗
Test fail condition
The nested file downloads without being flagged.
