Why this conclusion was reached

1/4 dimensions flagged
Pass
Declared vs actual capability

Declared resources and inferred behavior are broadly aligned.

Block
Hidden execution and egress

2 high-risk artifacts or egress signals were extracted.

Pass
Attack chain and severe findings

There is no explicit malicious chain in the report.

Review
Dependencies and supply chain hygiene

Dependency information is incomplete, so supply-chain confidence stays limited.

What drove the risk score up

IOC列表包含已知恶意IP +10

代码中IOC_IPS包含140.82.54.223,但这是用于检测已知恶意地址的标准实践,非实际连接

Base64编码模式检测 +10

SKILL.md中记录了eval(atob())作为检测模式,这是恶意软件检测工具的标准规则,非恶意行为

Most important evidence

Low

IOC列表包含已知恶意地址

代码IOC_IPS包含140.82.54.223,IOC_URLS包含calendar.app.google相关地址。这是安全检测工具的标准威胁情报库用法,非攻击代码。

scripts/pua.py:61
无需处理。这是用于检测已知恶意地址的标准实践。
Info

Base64编码模式检测规则

代码检测eval(atob())等危险代码模式,这是恶意软件检测的核心功能,非实际执行。

scripts/pua.py:67
无需处理。这是检测规则,不是攻击代码。
Info

仅使用Python标准库

脚本仅依赖Python标准库(base64, re, os, sys, json, pathlib, typing),无第三方依赖引入风险。

scripts/pua.py:1
无需处理。标准库可信。

Security positives

声称功能与实际代码完全一致,无文档-行为差异
仅使用Python标准库,无第三方依赖风险
无网络连接、文件写入、shell执行等敏感操作
代码结构清晰,检测逻辑合理
使用IOC列表进行威胁检测是行业标准实践
