PNGboomer-CVE-2026-77622

PNGboomer — CVE-2026-77622 针对 Sliver C2 的 HTTPS 监听器的拒绝服务攻击利用工具。通过暴力破解每个会话的 PNG 编码随机数，并投递一个解压炸弹来耗尽服务器内存。 已发布为 GHSA-663m-7x7m-g4fw。 概述 Sliver 的 HTTPS C2 通道将消息封装在 PNG 图像中。每个会话被分配一个范围在 1, 65537 内的随机随机数，服务器仅解码那些 ?n= 查询参数与会话随机数匹配的请求中的 PNG 数据。这是一种路由机制，而非身份验证检查——密钥空间仅为 16 位。 服务器使用 Go 的 image.Decode 解码...
