Security audit

Sano Intel — 中国医疗产业情报引擎（探针资本出品）

Security checks for vulnerabilities and agentic risk

Overview

The skill has a clear healthcare intelligence purpose, but it tells users to send an API token over unencrypted HTTP and optionally store it persistently in a shell profile.

Install only if you are comfortable sending API keys and healthcare or investment research queries to the listed service over plaintext HTTP. Prefer not to store the token in ~/.zshrc, use a temporary environment variable or a more secure secret store, and rotate the token if it has already been used on an untrusted network.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Missing User Warnings

High
Category
Not specified by scanner
Confidence
99% confidence
Finding

The skill instructs users to obtain and use an API token over plain HTTP endpoints, including sending the token in the X-API-Key header to an http:// API base. Because HTTP provides no transport encryption or server authentication, the token and returned data can be intercepted or modified by any on-path attacker, leading to credential theft and tampering.

External Transmission

Medium
Category
Data Exfiltration
Confidence
98% confidence
Finding

The documentation explicitly requires transmitting the SANO_TOKEN to an external service in an X-API-Key header over plain HTTP. This creates direct external transmission of a secret without encryption, making credential exposure especially likely on untrusted networks and enabling unauthorized API access or account abuse.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The instructions state that when the user asks in Chinese, the skill should automatically choose an interface and return results summarized in Chinese. This imposes a language behavior without indicating that users can choose another language, which is a natural-language locale policy concern.
