病毒功能简述：

病毒名称：Worm/MSN.SendPhoto.al
中文名：“性感相册”变种al
病毒长度：23040 字节
病毒类型：蠕虫
危险级别：★★
影响平台：Win 9X/ME/NT/2000/XP/2003
病毒描述：
Worm/MSN.SendPhoto.al“性感相册”变种al是蠕虫家族的最新成员之一，采用高级语言编写，并经过添加多层保护壳处理。“性感相册”变种al运行后，会自我复制到被感染计算机系统的“%SystemRoot%\system32\”目录下，并重新命名为“waccs.exe”（文件属性设置为：系统、隐藏、只读）。“性感相册”变种al会在被感染计算机的后台强行篡改用户系统中的HOSTS文件，利用域名映像劫持技术禁止用户访问与安全相关的网站。“性感相册”变种al在运行时，采用进程隐藏技术使自身的进程运行后不显示，这样可以使用户很难发现该病毒的存在。“性感相册”变种al在运行时，会在被感染计算机的后台将恶意可执行代码注入到系统桌面程序“explorer.exe”进程内存的空间中，并调用执行[其中，所注入的恶意代码的功能是：1、以共享方式打开"%SystemRoot%\system32\waccs.exe"文件，防止用户删除该病毒主程序文件。2、建立互斥量“t3x0”，利用进程守护技术原理，用系统“explorer.exe”进程来保护病毒主程序进程不被关闭(循环监视病毒主程序进程是否被关闭，如果发现被关闭则重新调用运行)。]。“性感相册”变种al会在被感染计算机系统的后台利用“E-MAIL”邮件和“MSN”等聊天工具进行群发恶意广告信息，可能还会利用“E-MAIL”邮件和“MSN”等聊天工具进行自我传播。“性感相册”变种al在运行时，会在被感染计算机系统的后台不段循环与骇客指定远程服务器（其中，通信地址为：“http://www.secure.freebsd.la”）进行秘密数据通信，接收从骇客服务器返回的数据包，根据包中骇客定义好的“指令”执行相应的恶意操作。“性感相册”变种al会通过在注册表启动项中添加新键的方式，来实现开机蠕虫病毒自启动。
