WHOIS

description
VanHelsing是一款于2025年3月上旬出现的新型勒索软件即服务（RaaS），由一个名为“VanHelsingRaaS”的组织或项目所提供。该RaaS对加盟者（affiliate）收取押金或提供免费模式，并约定支付分成模式：入侵者获得80%赎金收入，余下20%则由RaaS核心团队抽成。该组织禁止在独联体（CIS）区域进行加密活动，并宣称支持Windows、Linux、BSD、ARM与ESXi等多平台版本。短短两周内，该勒索团伙至少对三家受害组织发起攻击，并开价高达数十万美元至五十万美元不等的赎金。该RaaS向其加盟者提供专门的后台面板，用于控制和定制勒索软件的行为。VanHelsing勒索软件的Windows样本显示其采用C++编写，功能更新快速；最近的一个变体添加了多项命令行参数，用于控制加密范围、绕过安全机制、在网络内横向移动等。该勒索软件主要使用ChaCha20加密算法，并通过Curve25519进行密钥加密，还尝试删除系统快照以破坏本地备份。同时它可以枚举并加密本地及网络驱动器，若指定参数则可在被攻破的网络共享中自动复制并执行自身以扩大影响范围。研究者发现其仍有一些逻辑缺陷或尚未完成的功能，可见该勒索软件正处于持续演进过程中。
