Most tools rely on static analysis, but many recent supply chain attacks only trigger under specific conditions (CI, time delays, etc).

So I built kojuto, a tool that actually executes packages in a sandbox and tries to trigger malicious behavior.

It simulates CI environments, shifts time forward, and monitors syscalls to detect things like credential access, unexpected network connections, or process execution.

Would love feedback!
