# EAC usermode telemetry RE

## Targets
- `EasyAntiCheat_EOS.exe` / service processes
- Game-side EAC modules
- IPC to kernel device

## Questions to answer
- What is enumerated each heartbeat?
- What is cached vs sent remote?
- How are integrity failures reported?
- Packer/protector layer (if any)

## Method
1. Snapshot imports/exports + sections
2. Hook/log outbound TLS (sizes, cadence) without needing full crypto break
3. Cross-ref IOCTL calls with driver RE
4. Diff versions after EAC updates

## Pair with
`eac-kernel-driver-re`, `eac-ban-stack`, `network-protocol-re`.
