A、检查C盘根目录下是否存在Feedlist文件,如果不存在,就会开启880个线程向
www.symantec.com发起DoS(拒绝服务)式攻击。
B、病毒搜索从C到Z的所有盘符,寻找具有以下后缀名的文件:
avi
doc
jpg
mp3
mp4
wav
wma
xls
病毒找到后,会释放病毒复本,复本名字使用找到的文件的文件名加上.exe的组合。
比如:病毒找到一个mydoc.doc的文件,就会释一个名为mydoc.doc.exe的病毒复本。
C、病毒使用WORD文档的图标
· 系统修改:
A、创建互斥体“theta”(是被感染系统的计算机名)来保证病毒只运行
一次;
B、可能在临时目录(%temp%)内建任意数据的文件,然后使用“记事本”来打开这个文件,
以达到欺骗用户的目的;
C、在系统目录(%system%)内创建以下文件
%system%<随机字符>.exe 病毒主程序的复本
%system%<随机字符>.dll 病毒实后门功能的模块
D、利用.dll文件打开后门在TCP端口80和1080进行监听,允许被感染系统做为代理服务器,
或是自动下载并执行其它程序;
E、终止许多系统进程并且尝试删除这些进程对应的程序。这些进程名所对应多为被病毒软件
的程序或是其它病毒的复本。
