GitToQuark
纯文档型技能,声明了复杂的文件下载、shell执行和凭证管理能力,但实际不包含任何代码文件(引用scripts/但不存在),存在供应链注入风险
SKILL.md引用scripts/quark-drive.cjs和scripts/install.sh,但package中没有任何脚本文件。技能完全依赖外部下载的CLI二进制。
SKILL.md:14 Why this conclusion was reached
1/4 dimensions flaggedDeclared resources and inferred behavior are broadly aligned.
8 lower-risk artifacts were extracted and still need context.
The report includes 4 attack-chain steps and 3 severe findings.
1 dependency or supply-chain issues need attention.
Attack Chain

Escalation · SKILL.md:52
Escalation · SKILL.md:59
Impact · 外部二进制
What drove the risk score up
声明scripts/quark-drive.cjs和scripts/install.sh但package中不存在
下载外部CLI无hash/signature校验,fallback URL固定版本
技能实际行为完全取决于外部下载的CLI,无法预判
SKILL.md描述的CLI行为与实际下载的二进制可能不一致
Most important evidence
无实际代码实现
SKILL.md引用scripts/quark-drive.cjs和scripts/install.sh,但package中没有任何脚本文件。技能完全依赖外部下载的CLI二进制。
SKILL.md:14 外部CLI下载无完整性校验
从GitHub releases下载最新版本quarkclouddrive,或从固定fallback URL下载1.0.15版本,均无SHA256/hash校验
SKILL.md:59 固定版本fallback URL存在
当GitHub API失败时,使用硬编码的pdds.quark.cn URL下载固定版本1.0.15,该域名可能被用于定向投毒
SKILL.md:59 凭证存储但未声明访问范围
技能将token存储到~/.quarkclouddrive/,虽然声明不读取,但外部CLI可能访问其他敏感路径
SKILL.md:71 第三方代理服务不可控
CN用户通过gh-proxy.com、ghproxy.net、v6.gh-proxy.org代理下载,代理节点可能进行流量嗅探或篡改
SKILL.md:31 Declared capability vs actual capability
SKILL.md:76-77 curl -L -o temp file downloads SKILL.md:27-31 curl to ipinfo.io, GitHub API, proxy services SKILL.md:42 node scripts/quark-drive.cjs; SKILL.md:56 bash scripts/install.sh SKILL.md:90 OPENCLAW_SERVICE_MARKER injection SKILL.md:71-72 stores tokens to ~/.quarkclouddrive/ Suspicious artifacts and egress
