Security audit

安全情报雷达

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed security-feed helper that stores local scan state and fetches advisory data, with no artifact-backed evidence of hidden exfiltration or destructive behavior.

Before installing, confirm you want a security-monitoring skill that may run shell commands, fetch advisory feeds, and maintain local inventory/cache/state under ~/.skill-platform/security-radar. Configure RADAR_FEED_URL only to a feed you trust and review any scan.sh implementation before scheduling heartbeat or CI runs.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Findings (6)

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger list is extremely broad and includes common terms like “安全”, “security”, “threat”, and “feed”, which can cause the skill to activate in unrelated conversations. Because the skill exposes exec and is designed to fetch remote data and manipulate local state files, unintended activation increases the chance of surprise shell execution paths, network access, and noisy or unsafe automation.

Session Persistence

Medium
Category
Rogue Agent
Confidence
88% confidence
Finding

The skill explicitly creates persistent state under ~/.skill-platform/security-radar, including assets, cache, and state files, which means it establishes long-lived local session data. Persistent security telemetry and asset inventories can be sensitive; if users are not clearly informed, this persistence may create privacy, retention, and forensic risks, especially on shared systems.

资产清单是过滤的基础。把已安装的技能、依赖、运行时版本写入清单文件:

bash
mkdir -p ~/.skill-platform/security-radar
cat > ~/.skill-platform/security-radar/assets.json <<'EOF'

  "schema_version": "1.0",

Sudo/Root Execution

Medium
Category
Privilege Escalation
Confidence
80% confidence
Finding

Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
82% confidence
Finding

The skill discusses correlating local assets and dependencies with external intelligence feeds but does not clearly state what local metadata may be transmitted to third parties during enrichment, lookup, or future implementation changes. In a security tool, asset inventory, dependency versions, and runtime details can be sensitive and may expose an organization’s attack surface if sent externally.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
90% confidence
Finding

The quick-start section instructs users to create directories and write persistent files under the home directory without a prominent warning that local filesystem state will be modified. While the commands are not inherently malicious, hidden persistence and config creation can surprise users and create trust and auditability problems in an agent context.
