External Builders

Starting in v1.5.30 Sliver supports "external builders," which allow a Sliver server to offload implant builds onto other systems. This can be used to increase platform support (e.g. connecting a MacBook to Linux server to enable additional MacOS targets) or increasing performance (e.g. having a low powered cloud host offload a local PC).

External builders can also be used to create custom modifications to the implant source code, or replace the default Sliver implant entirely.

Builders

Setup

Any sliver-server binary can be started as a builder process using operator configuration files from multiplayer-mode, for example:

./sliver-server builder -c operator-multiplayer.cfg

When started as a builder, the Sliver server will mirror log output to stdout by default, however this can be disabled (see sliver-server builder --help).
