一.  什么是LibOSlIbOS的全称是library operating system，即“库操作系统”。顾名思义，lIbOS的主要作用是将一些原本属于操作系统的服务（如网络通信、文件系统等）进行

本文简单介绍了LibOS技术与两个实现LibOS的开源项目：Gramine与occlum。我们展示了这两个项目如何利用LibOS来简化SGX应用的开发工作。此外本文还通过示例分析展示了如何利用这两个开源项目，快速上手SGX应用开发。

卡巴斯基研究人员观察到，与朝鲜有关的Lazarus Group在一个月的时间里至少针对了两名与同一核相关组织有关的员工。 专家们认为，这些攻击是网络间谍活动“梦想工作行动”（Operation Dream Job，又称NukeSped）的一部分，该行动自至少2020年以来一直在进行。 攻击者使用了复杂的感染链，包括多种类型的恶意软件，如下载器、加载器和后门。这个国家级行为者向两名员工发送了包含恶意文件的压缩文件。 Lazarus Group利用恶意ISO文件来逃避检测，部署了木马化的VNC软件，以传递如Ranid Downloader、MISTPEN、RollMid和LPEClient等恶意软件。 研究人员还在受感染的主机上发现了CookieTime恶意软件，该恶意代码在LPEClient安装后以SQLExplorer服务激活，最初执行C2命令，但现在主要用于下载有效载荷。 攻击者使用CookieTime下载了多种恶意软件，包括LPEClient、Charamel Loader、ServiceChanger和更新版的CookiePlus。Charamel Loader使用ChaCha20算法解密并加载如CookieTime、CookiePlus和ForestTiger等恶意软件。 攻击者使用ServiceChanger恶意软件停止了一个合法服务，在磁盘上存储恶意文件，并重启服务以通过侧加载加载恶意DLL。Lazarus Group针对ssh-agent服务使用了libcrypto.dll，与Kimsuky APT组织利用现有服务而不是注册新服务的方法不同。在某些情况下，CookieTime也通过DLL侧加载被加载，并且支持多种加载方法和不同的入口点。 “由于CookiePlus充当下载器，它的功能有限，并且只从受感染的主机向C2服务器传输最少的信息。在其与C2的初始通信中，CookiePlus生成了一个32字节的数据数组，其中包括其配置文件中的ID、特定偏移量和计算步骤标志数据。”报告中写道。 研究人员认为CookiePlus可能是MISTPEN的继任者。尽管两者没有代码重叠，但都伪装成Notepad++插件，并使用类似的策略，如利用TBaseInfo.dll和hiber.dll等插件。CookiePlus在2024年6月被编译和使用，看起来更为先进，与2024年初已知的MISTPEN样本相比，支持额外的执行选项。 Lazarus Group APT组织在大部分活动中使用了被破坏的WordPress网络服务器作为C2。这些服务器被MISTPEN、LPEClient、CookiePlus和RollMid恶意软件用作C2。然而，CookieTime只使用了一个基于WordPress的C2。所有已识别的C2托管了分布在不同国家的基于PHP的网络服务。 “在其历史上，Lazarus Group只使用了少量的模块化恶意软件框架，如Mata和Gopuram Loader。引入这种类型的恶意软件对他们来说是一种不寻常的策略。他们确实引入了新的模块化恶意软件，如CookiePlus，这表明该组织正在不断努力改进他们的武器库和感染链，以逃避安全产品的检测。”报告总结道。“对于防御者来说，问题是CookiePlus可以表现得像一个下载器。这使得调查CookiePlus是否只下载了一个小插件或下一个有意义的有效载荷变得困难。从我们的分析来看，它似乎仍在积极开发中，这意味着Lazarus Group未来可能会添加更多插件。”       消息来源：securityaffairs；  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
