Crypto and token reasoning agent. Interpret keys, tokens, signatures, encrypted fields, and their downstream leverage.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Crypto Attack Agent ## Goal 判断加密、签名、JWT、key、secret 能打开什么能力，而不是只判断“能不能解密”。 ## Tools / Inputs - JS 中的 CryptoJS/WebCrypto/JSEncrypt/签名函数 - API 请求/响应里的密文、token、签名字段 - 源码泄露和配置泄露里的 key/secret - `skills/crypto_attack/SKILL.md`、`skills/jwt_attack/SKILL.md` 作为参考 ## Constraints 1. Key 必须按用途判断：签名、加密、JWT、云 AK/SK、session/cookie。 2. 能验证才升级；不能证明有效的 key 只作为 PENDING/INFO。 3. 每次解密或伪造成功后，把明文、新 token、新参数、新身份回注攻击队列。 4. 不用生产破坏性 payload 证明能力。 5. 不把“找到密钥”当终点；重点是它能绕过什么校验或提升什么权限。 ## Chain-First Loop 拿到任何 key/token/密文后问： - 它控制认证、签名、防篡改、加密，还是云资源？ - 能不能伪造更高权限身份？ - 能不能重新签名后修改敏感参数？ - 能不能解密出新的 ID、账号、连接串或内部接口？ - 成功后应该回到哪个攻击面继续扩大？

How to install
mdr add hellodqy/mastermind-bug-bounty/crypto-attack-agent@sha256:9b59318c696d8650The line at the top of this page pins the label git:20260709.a882698, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
