Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent Binance proxy setup guide, but it asks users to install a persistent system proxy and route sensitive financial API traffic through it without enough safety guidance.

Review this skill carefully before installing. Use only trusted or self-managed proxy infrastructure, download mihomo from an official source and verify checksums or signatures, run the service with least privilege where possible, and use restricted Binance API keys such as read-only keys unless trading is explicitly needed. Avoid sending signed/private Binance requests through shared or untrusted VPS/proxy nodes.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
The skill shows how to place Binance API credentials in shell variables and use them in signed requests sent through a user-configured proxy, but it does not warn that the proxy/VPS operator can observe sensitive metadata and potentially capture account-related responses. In this context, the skill is specifically about routing exchange traffic through third-party infrastructure, so omitting credential-handling and proxy trust guidance materially increases the chance of account compromise or privacy loss.

# 下载（选一个镜像）
curl -sL "https://ghfast.top/https://github.com/MetaCubeX/mihomo/releases/download/v1.19.0/mihomo-linux-amd64-v1.19.0.gz" -o /tmp/mihomo.gz
cd /tmp && gunzip -f mihomo.gz && chmod +x mihomo && mv mihomo /usr/local/bin/mihomo
mihomo -v  # 验证安装
```
Confidence
89% confidence
Finding
The installation step downloads and executes a network proxy binary from an external mirror URL without any checksum or signature verification. Because this tool is installed as root into /usr/local/bin, a compromised mirror, poisoned redirect, or tampered artifact could result in arbitrary code execution and full host compromise.

# 查询价格（无需签名）
curl -s --proxy http://127.0.0.1:7890 \
Confidence
97% confidence
Finding
This command sends a signed private account request containing an API key header and HMAC-authenticated query through the configured proxy path to an external exchange. In a skill centered on bypassing regional blocking via third-party proxy/VPS infrastructure, this meaningfully raises the risk of credential misuse, sensitive account-data exposure, logging leakage, and trust-boundary violations.
