VPS 维护配置

Security checks across malware telemetry and agentic risk

Overview

This VPS maintenance skill is not deceptive, but it provides root-level commands that can lock users out or delete system data if followed as-is.

Install only if you are comfortable reviewing root-level server administration commands before use. Keep an active recovery path such as provider console access, adapt the SSH port/firewall/timezone/NTP choices to your host, test access before enabling restrictive firewall rules, and replace the broad cleanup commands with safer dry-run or age-based cleanup for production systems.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The cleanup section includes irreversible deletion and package removal commands such as purging kernels, deleting logs, and wiping temporary/cache directories, but it does not warn the user about possible data loss, service disruption, or the risk of deleting files still needed by running processes. In a VPS maintenance skill, users are likely to copy-paste these commands as root, which increases the chance of accidental operational damage.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The recurring cleanup script automates destructive operations including apt autoremove and deletion of log and temporary files, yet it provides no caution about irreversible effects or application impact. As a reusable script for periodic execution, this is more dangerous than one-off manual commands because mistakes can recur automatically.

Natural-Language Policy Violations

Medium
Confidence
88% confidence
Finding
The skill unconditionally sets the timezone to Asia/Shanghai and configures region-specific NTP servers without asking the user to confirm the server's region or operational requirements. This can cause audit/logging confusion, timestamp inconsistencies, and operational errors in environments where UTC or another timezone is required.
