kannaka-node@1.0.2

CAUTION· install only

Publisher claims: "Hand a fresh Linux server to an AI and get back a running Kannaka node. Given an IP or hostname and SSH access, the agent checks the box, installs the signed Kannaka release, writes the node's identity, wires it as a systemd service that joins the constellation swarm and keeps its memory in sync, dreams nightly, and proves it is alive before handing it back. Works on Oracle Cloud free tier (Oracle Linux, aarch64), Ubuntu, Debian, Fedora. Use when someone says "set up a kannaka server", "provision a node", "here is my server, make it a kannaka node", or asks how to install kannaka on a VPS." Observed in sandbox: no network, touches nothing outside the project, writes no memory.

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario; nothing executable in the bundle ran; the trace covers the install step only) on 2026-11-07 and scored it 73/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Privileged sudo command; Privileged sudo command; Pipe-to-shell pattern. Summary: no network, touches nothing outside the project, writes no memory.
