Description
A spoofing vulnerability exists in the way Windows CryptoAPI (Crypt32.dll) validates Elliptic Curve Cryptography (ECC) certificates.An attacker could exploit the vulnerability by using a spoofed code-signing certificate to sign a malicious executable, making it appear the file was from a trusted, legitimate source, aka 'Windows CryptoAPI Spoofing Vulnerability'.

这资源是作者复现微软签字证书漏洞CVE-2020-0601，结合相关资源及文章实现。推荐大家结合作者博客，理解ECC算法、Windows验证机制，并尝试自己复现可执行文件签名证书和HTTPS劫持的例子。作为网络安全初学者，自己确实很菜，但希望坚持下去，加油！

CurveBall (CVE-2020-0601) - PoC CVE-2020-0601, or commonly referred to as CurveBall, is a vulnerability in which the signature of certificates using elliptic curve cryptography (ECC) is not correctly verified. Attackers can supply hand-rolled generators, bypassing validation, antivirus & all non-protections.
