crypto-attack SKILL.md skillA
crypto-attack from hellodqy/mastermind-bug-bounty is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hellodqy/mastermind-bug-bounty/crypto-attack@git:20260709.c284c01Pins git:20260709.c284c01 in mdr.lock. Pin the fingerprint instead.

Interpret encryption, signing, encoding, and key material as leverage for later attack-chain expansion.
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 ## Goal 判断加密/签名机制能否被理解、重放、重签、解密或绕过，并把获得的新能力连接到 API、JWT、IDOR 或报告证据。 ## Tools / Inputs - JS 加密函数、密文、签名字段、key/iv/secret、编码字段 - 资源索引：`references/INDEX.md`；候选资源：`crypto-analysis.md` ## Constraints 1. Key 要按用途分类：签名、加密、JWT、云、Cookie/session。 2. 只有可验证利用才升级为漏洞。 3. 解密出的明文必须回写值池。 4. 重新签名后的参数变更必须用无害样本证明。 5. 不把“算法弱”当漏洞，除非证明影响。 ## Chain Questions - 这个 key 能让哪些原本不可改的参数变得可控？ - 解密后是否出现账号、ID、token、内部接口或连接串？ - 重新加密/签名能否绕过后端校验？ - 新能力应该回到哪个攻击面继续扩展？

How to install
mdr add hellodqy/mastermind-bug-bounty/crypto-attack@sha256:b7d2e7a33f176148The line at the top of this page pins the label git:20260709.c284c01, 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.
