IRONSQUIRREL This project aims at delivering browser exploits to the victim browser in an encrypted fashion. Ellyptic-curve Diffie-Hellman secp256k1 is used for key agreement and AES is used for encryption. By delivering the exploit code and shellcode to the victim in an encrypted way, the attack...
Linux Distros Unpatched Vulnerability : CVE-2026-93160
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - crypto: atmel-ecc - reject hardware ECDH without a public key The hardware ECDH path in atmelecdhcomputesharedsecret uses the private key stored in the device...
AZL-102192 CVE-2026-93160 affecting package kernel 6.6.150.1-1
In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-ecc - reject hardware ECDH without a public key The hardware ECDH path in atmelecdhcomputesharedsecret uses the private key stored in the device. However, the public key is cached only after atmelecdhsetsecret...

CVE-2026-33936
CVE-2026-33936 ecdsa PyPI 中的拒绝服务漏洞 介绍 我在 python-ecdsa 中识别并负责任地披露了一个 中等严重性 的漏洞，这是一个广泛使用的 Python 加密库，过去一个月有 4780 万次下载 。 我在审查 python-ecdsa 时发现了这个问题，心中带着一个非常具体的问题： 如果格式错误的 DER 虚假地声称其长度，而解析器过度信任该长度，会发生什么？ 在这个案例中，这个问题引出了一个真实漏洞。 ecdsa.der 中的 DER...

椭圆曲线密码学的已知攻击 介绍 椭圆曲线简介 密码学中的椭圆曲线 ECC 攻击 ECDH 攻击 生成元的阶太小 生成元的阶是光滑数 生成元的阶几乎是光滑数，且私钥很小 不验证点是否在曲线上 曲线是奇异曲线 曲线是超奇异曲线 曲线是异常曲线 ECDSA 攻击 签名前不对消息进行哈希 在不同签名中重用相同的 k 值 不安全地生成 k 值 不验证生成元是否有效 结论 ECDH 攻击概述 ECDSA 攻击概述 防御这些攻击 参考资料 介绍 近年来，椭圆曲线密码学方法因其高效性和强安全性而变得流行。本文旨在以比当前互联网上已有的资料更清晰的方式介绍这一主题。...
CVE-2023-54355
PocketMine-MP versions before 5.3.1 and 4.23.1 fail to validate that the identityPublicKey in LoginPacket uses the required secp384r1 elliptic curve. Attackers can provide LoginPackets with keys using different curves or non-EC key types to pass login verification but trigger an uncaught exceptio...
