Как ботнет Kimwolf заразил уже почти 2 миллиона Android-устройств по всему миру.

HackerNews 编译，转载请注明出处： 根据奇安信XLab的研究，一个名为Kimwolf的新型分布式拒绝服务僵尸网络已组建了一支由至少180万台受感染设备组成的大军，这些设备包括基于安卓系统的电视、机顶盒和平板电脑，并且可能与另一个名为 AISURU 的僵尸网络存在关联。 “Kimwolf是一个使用NDK编译的僵尸网络，” 该公司在今天发布的一份报告中表示。”除了典型的DDoS攻击能力外，它还集成了代理转发、反向Shell和文件管理功能。” 据估计，这个超大规模僵尸网络在2025年11月19日至22日的三天内发出了17亿条DDoS攻击命令。大约在同一时间，其一个C2域名曾登顶Cloudflare的全球前100域名榜单，甚至一度短暂超越谷歌。 Kimwolf的主要感染目标是部署在家庭网络环境中的电视盒子。部分受影响的设备型号包括TV BOX、SuperBOX、HiDPTAndroid、P200、X96Q、XBOX、SmartTV和MX10。感染分布在全球，其中巴西、印度、美国、阿根廷、南非和菲律宾的感染密度较高。然而，恶意软件传播到这些设备的具体方式目前尚不清楚。 XLab表示，其调查始于2025年10月24日从一位可信的社区合作伙伴处收到Kimwolf的”第四版”样本。自那以后，上月又发现了另外八个样本。 “我们观察到，Kimwolf的C2域名至少被未知方成功关闭了三次，迫使其升级策略，转而使用ENS来强化其基础设施，这展示了其强大的进化能力，” XLab研究人员说。 不仅如此，本月早些时候，XLab成功夺取了其中一个C2域名的控制权，从而得以评估该僵尸网络的规模。 Kimwolf一个有趣的方面是它与臭名昭著的AISURU僵尸网络有关联，后者是过去一年中一些破纪录DDoS攻击的幕后黑手。据推测，攻击者在早期阶段重用了AISURU的代码，后来才选择开发Kimwolf僵尸网络以规避检测。 XLab表示，其中一些攻击可能并非仅来自AISURU，Kimwolf可能参与甚至主导了这些攻击。 “这两个主要的僵尸网络在9月至11月期间通过相同的感染脚本传播，共存于同一批设备中，” 该公司表示。”它们实际上属于同一个黑客组织。” 这一评估基于上传到VirusTotal平台的APK包的相似性，在某些情况下甚至使用了相同的代码签名证书。2025年12月8日发现了更确凿的证据：一个活跃的下载服务器被发现包含一个同时引用Kimwolf和AISURU APK文件的脚本。 恶意软件本身相当直接。一旦启动，它会确保在受感染设备上只运行一个进程实例，然后继续解密嵌入的C2域名，使用基于TLS的DNS获取C2 IP地址，并连接到该地址以接收和执行命令。 截至2025年12月12日检测到的最新版本僵尸网络恶意软件引入了一种名为EtherHiding的技术，该技术利用ENS域名从相关的智能合约中获取实际的C2 IP地址，旨在使其基础设施对打击行动更具弹性。 具体来说，这涉及到从事务的”lol”字段中提取IPv6地址，然后取该地址的最后四个字节，并用密钥”0x93141715″进行异或运算以得到实际的IP地址。 除了加密与C2服务器和DNS解析器相关的敏感数据外，Kimwolf还使用TLS加密进行网络通信以接收DDoS命令。总体而言，该恶意软件支持13种基于UDP、TCP和ICMP的DDoS攻击方法。根据XLab的数据，攻击目标位于美国、中国、法国、德国和加拿大。 进一步分析确定，超过96% 的命令涉及使用僵尸节点提供代理服务。这表明攻击者试图利用受感染设备的带宽并最大化利润。作为这项工作的一部分，一个基于Rust的命令客户端模块被部署以形成代理网络。 同时分发给节点的还有ByteConnect SDK，这是一个允许应用程序开发者和物联网设备所有者将其流量货币化的变现解决方案。 “巨型僵尸网络起源于2016年的Mirai，感染目标主要集中在家庭宽带路由器和摄像头等物联网设备上，” XLab表示。”然而，近年来，诸如Badbox、Bigpanzi、Vo1d和Kimwolf等百万级别的巨型僵尸网络信息被披露，这表明一些攻击者已经开始将注意力转向各种智能电视和电视盒子。” 消息来源：thehackernews； 本文由 HackerNews.cc 翻译整理，封面来源于网络； 转载请注明“转自 HackerNews.cc”并附上原文

文章描述了错误代码521的问题及其常见原因和影响。

HackerNews 编译，转载请注明出处： 据卡巴斯基称，与”论坛巨魔行动” 相关的威胁行为者被确认为近期一系列针对俄罗斯境内人士的钓鱼攻击的幕后黑手。 这家俄罗斯网络安全厂商表示，其在2025年10月检测到这一新活动。该威胁行为者的来源目前尚不清楚。 “春季的网络攻击主要针对组织，而秋季的活动则瞄准了特定的个人：在俄罗斯主要大学和研究机构工作的政治学、国际关系和全球经济领域的学者，” 安全研究员 Georgy Kucherin 说。 “论坛巨魔行动”指的是一系列利用Google Chrome浏览器中一个零日漏洞 进行复杂钓鱼攻击的活动，旨在传播LeetAgent后门 和名为Dante的间谍软件植入程序。 最新的攻击浪潮同样始于伪装成 “俄罗斯科学电子图书馆” 发送的钓鱼邮件，发件地址为 “support@e-library[.]wiki”。该域名注册于2025年3月，比攻击活动开始早了六个月，这表明攻击准备工作已经进行了一段时间。 卡巴斯基指出，这种策略性的域名老化处理是为了避免因使用新注册域名发送邮件而引发通常的危险信号。此外，攻击者还在虚假域名上托管了合法eLibrary首页的副本，以维持骗局。 这些邮件引导潜在目标点击指向恶意网站的嵌入链接，以下载所谓的”抄袭报告”。一旦受害者照做，一个命名格式为 “<姓氏><名字><父称>.zip” 的ZIP压缩包便会下载到其设备上。 更重要的是，这些链接设计为一次性使用，意味着任何后续尝试访问该URL的操作都会显示一条俄语消息：”下载失败，请稍后再试”。如果用户从非Windows平台尝试下载，则会被提示”请在Windows电脑上重试”。 “攻击者还针对他们的目标——该领域的特定专业人士——精心个性化设计了钓鱼邮件，” 该公司表示。”下载的压缩包以受害者的姓氏、名字和父称命名。” 压缩包内含一个同名Windows快捷方式文件。当此LNK文件被执行时，会运行一个PowerShell脚本，从远程服务器下载并启动一个基于PowerShell的载荷。随后，该载荷会联系一个URL以获取最终阶段的DLL文件，并通过COM劫持实现持久化。同时，它还会下载并向受害者展示一个诱饵PDF文件。 最终的有效载荷是一个名为 Tuoni 的命令与控制及红队框架，使威胁行为者能够远程访问受害者的Windows设备。 “自2022年起，ForumTroll就一直在针对俄罗斯和白俄罗斯的组织和个人，” 卡巴斯基表示。”鉴于这段漫长的时间线，该APT组织很可能会继续针对这两个国家内感兴趣的实体和个人。” 此次披露之际，Positive Technologies详细介绍了两个威胁集群的活动：QuietCrabs（一个被怀疑是中国黑客组织，亦被追踪为UTA0178和UNC5221）和Thor（后者似乎自2025年5月起参与了勒索软件攻击）。 研究发现，这些入侵集合利用了Microsoft SharePoint、Ivanti Endpoint Manager Mobile、Ivanti Connect Secure 以及 Ivanti Sentry 中的安全漏洞。 QuietCrabs发起的攻击利用初始访问权限部署ASPX Web Shell，并用其传播能够下载并执行KrustyLoader 的JSP加载器，进而投放Sliver植入程序。 “Thor是一个在2025年首次被观察到攻击俄罗斯公司的威胁组织，” 研究人员 Alexander Badayev、Klimentiy Galkin 和 Vladislav Lunin 说。”作为最终载荷，攻击者使用LockBit和Babuk勒索软件，以及Tactical RMM和MeshAgent 来维持持久性访问。”     消息来源：thehackernews； 本文由 HackerNews.cc 翻译整理，封面来源于网络； 转载请注明“转自 HackerNews.cc”并附上原文
