آشنایی با ویروس

Kickin

نام كرم :Kickin

نام مستعار :I-Worm.Cydog.c, W32/Cydog.D, W32/Kickin@MM, Cydog.D, W32/Kickin.A@mm این كرم كه به نامKickin معروف است درTH7May  سال 2003 كشف شد.این كرم دارای حجم 109056 بایتی بوده و بوسیله سیستمUPX  فشرده شده است .Kickin خیلی شبیه كرمCydog بوده و می توان گفت كه نسخه  دوباره نویسی شده در زبانVisual C كرم Cydog است. این كرم می تواند  از طریق ایمیل در سرور هایIRC و P2P و شبكهKazaa و Edenkey و Beashare و Morpheus توسعه یافته و منتشر شود.

آلوده كردن سیستم :

وقتی كرم اجرا می شود ، خود را در دایركتوری ویندوز به نام Cyberwolf.exe با قابلیت مخفی فایل و شهرت فایل ذخیره می كند و یك نسخه از خود را نیز در شاخه سیستم ویندوز و با نام های زیر كپی می كند  :

mapi32.drvformat.comSARS-Guide.scrMsnMsgs.exeSetup.exeVirtual Joke.scrSaddam-the real pics.scrChristina Aguilera-The most beautiful girl on earth.scrSoccer Database.exeOutWar Demo.exeLove.scrLast Summer.scrHotmail Hacker.exeFixSql.comQ30215HOTFIX.pifApi Hooking-Tutorial.exeKernel32.exeMagical-Screensaver.scr

این كرم وِژگی مخفی به فایل ها می دهد و  هر وقت كه فایلی با پسوندExe اجرا می شود فایل Kernel32.exe باز خوانی می شود . برای انجام این كار كدی همانند زیر به رجیستری می افزاید :

[HKCR/exefile/shell/open/command] @ =  "%winsysdir%/Kernel32.exe"%1"%*""

در ضمن كرم دو كلیدstart up برای خود و به شرح زیر  می سازد:

[HKLM/Software/Microsoft/Windows/CurrentVersion/Run] "CyberWolf" = "%windir%/CyberWolf.exe" "Windows Kernel" = "%winsysdir%/Kernel32.exe"

%Windir محل نصب ویندوز (شاخه ویندوز) و%Winsysdir محل شاخه سیستم است و این كد ها با هر بار اجرای ویندوز و به علت راه اندازی مجدد رجیستری باعث فعال شدن كرم می شوند

انتشار از طریق ایمیل :

این كرم آدرس های مورد نظر خود را از طریق كتاب آردس ایمیل های سیستم یا كتاب آردس یاهو مسنجر وMSN و مسنجر.NET ،  آدرس بوكICQ  یا آردس های وارد شده در صفحات HTML و EML یافته و خود را به آن آردس ها كپی می كند.

این كرم دارای لیستی ازSMTP های مختلفی است كه سعی می كند تا دذر صورت غیر فعال بودن سیستم SMTP قربانی از آنها  استفاده كند . كرم می تواند خود را با Subject ها و Body های مختلفارسال كند.  اسم فایل ضمیمه ویروس نیز متغییر  است . مثل :
