HackerNews 编译，转载请注明出处： 网络安全研究人员发现一种名为“Plague”的新型Linux后门程序，该恶意软件已逃避检测长达一年之久。Nextron Systems研究员Pierre-Henri Pezier指出：“该植入程序被构建为恶意PAM（可插拔认证模块），使攻击者能静默绕过系统认证，获取持久SSH访问权限”。 可插拔认证模块（Pluggable Authentication Module，PAM）是Linux及UNIX系统中用于管理用户对应用程序和服务认证的共享库集合。由于PAM模块会被加载至特权认证进程中，恶意模块可实现凭证窃取、绕过认证检查，同时规避安全工具检测。 该网络安全公司表示，自2024年7月29日起，其在VirusTotal平台发现多个Plague样本，但所有反恶意引擎均未将其标记为恶意。此外，多个样本的存在表明幕后未知威胁组织正积极开发该恶意软件。 Plague具备四项核心能力： 静态凭证：支持隐蔽访问 抗分析能力：通过反调试与字符串混淆技术抵抗逆向工程 会话痕迹清除：通过取消设置环境变量（如SSH_CONNECTION、SSH_CLIENT）及重定向HISTFILE至/dev/null，阻止Shell命令记录，从而消除审计痕迹 Pezier强调：“Plague深度集成于认证堆栈中，可存活于系统更新过程且几乎不留取证痕迹。结合分层混淆与环境篡改技术，使其极难被传统工具检测。”       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

HackerNews 编译，转载请注明出处： 东南亚电信组织近期遭国家级威胁组织CL-STA-0969定向攻击，该组织通过部署定制化工具实现对目标网络的远程控制。Palo Alto Networks旗下Unit 42实验室披露，2024年2月至11月期间监测到多起针对该地区关键电信基础设施的攻击事件，攻击者利用Cordscan等工具收集移动设备位置数据。 值得注意的是，调查人员在受感染系统和网络中未发现数据外泄证据，也未观察到攻击者尝试追踪或联络移动网络内部设备。研究人员强调：“该威胁组织具备极高的操作安全（OPSEC）规范，综合运用多种防御规避技术躲避检测”。 该组织自2020年起持续针对南亚、非洲电信实体实施情报窃取活动。部分攻击手法还与“LightBasin”（又名UNC1945）及金融犯罪组织“UNC2891”存在关联——后者以劫持ATM基础设施著称。 攻击者通过SSH认证机制的暴力破解获取访问权限，采用针对电信设备内置账户的定制化字典列表实施突破。 恶意工具链 AuthDoor：覆盖合法PAM模块实施凭证窃取，通过硬编码魔术密码维持持久访问 GTPDoor：滥用GPRS隧道协议控制面（GTP-C）在电信漫游网络建立隐蔽C2通道 EchoBackdoor：通过ICMP回显请求数据包被动接收指令，未加密返回执行结果 SGSN模拟器：模拟服务GPRS支持节点，绕过企业防火墙限制 ChronosRAT：模块化ELF后门支持远程Shell、键盘记录及端口转发 NoDepDNS：基于Golang的DNS隧道后门，通过原始套接字解析53端口UDP指令 防御规避 攻击组合利用DNS隧道传输流量、通过被控移动运营商中转通信、清除认证日志、禁用SELinux安全模块及进程名称伪装等技术。同时部署Microsocks代理、FRP反向代理及ProxyChains等公开工具，并利用Linux本地提权漏洞（CVE-2021-4034等）扩大控制范围。 本次披露恰逢中国国家计算机网络应急技术处理协调中心（CNCERT）指控美国情报机构： 利用Microsoft Exchange零日漏洞（2022年7月-2023年7月）窃取中国军工企业国防情报 针对高科技军事院校及科研机构实施数据窃取 2024年7-11月通过电子文件系统漏洞攻击中国通信卫星企业 对此，美国前总统特朗普曾公开承认：“我们同样对他们实施网络行动，这就是世界的运行规则。”       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
