Skill Trust Decision
defender2
defender2是一个合法的NPM恶意软件检测工具,声称功能与实际代码行为一致,使用IOC列表检测已知恶意IP是标准威胁情报实践。
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。
Declared capability vs actual capability

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
