hunt-deserialization skillA

hunt-deserialization is agent-read markdown (skill) from galact-byte/galact-skills: 在授权渗透测试中挖掘不安全反序列化（insecure deserialization）。当目标把用户可控数据交给 unserialize/Marshal/pickle/ObjectInputStream/BinaryFormatter/YAML.load 等还原成对象时使用——典型场景：cookie/token/viewstate/隐藏字段里出现序列化数据、导入文件触发对象还原、想借 gadget chain 拿 RCE。适用目标类型 Web / REST API（PHP/Ruby/Python/Java/.NET）。触发场景包括用户说"测下反序列化""这个 cookie 是不是序列化对象""能不能 gadget chain 打 RCE""phar/Marshal/pickle 打一下"。输出：识别出的序列化落点 + gadget 可用性判定 + 带外/回显证据的 finding（含 killed 记录）。.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add galact-byte/galact-skills/hunt-deserialization@git:20260806.1b94651
Exact content
mdr add galact-byte/galact-skills/hunt-deserialization@sha256:05f4b5a3fb8e3b08

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
