"mindjail.zip" contains a HTML file, "mindjail.html", which drops and executes "javax.sun.base.exe" (MD5: 286b884697dffd5a535295dcf5a4c6ea) on vulnerable systems - see "Self-Executing HTML: Internet Explorer 5.5 and 6.0 Part II", <http://www.securityfocus.com/archive/1/313174>, for more information about the vulnerability. "javax.sun.base.exe" is an upx'ed SdBot variant. It tries to connect to "hk.zxy0.com" [64.156.241.176]. The most anti virus scanners fail to detect the exploit code and the backdoor trojan. But a few scanners report the following: [MINDJAIL.HTML] Dialogue Science DrWebWCL : Trojan.SelfExecHtml GeCAD RAVAV : HTML/CodeBaseExec* Kaspersky Lab KAVDOS32 : TrojanDropper.JS.Mimail.b Symantec NAV CE VSCAND : Trojan.Sefex [JAVAX.SUN.BASE.EXE] GeCAD RAVAV : Backdoor:IRC/SdBot Kaspersky Lab KAVDOS32 : Backdoor.SdBot.gen Regards, Axel Pettinger ---------------------------------------------------------------------------- Attend the Black Hat Briefings & Training, July 28 - 31 in Las Vegas, the world's premier technical IT security event! 10 tracks, 15 training sessions, 1,800 delegates from 30 nations including all of the top experts, from CSO's to "underground" security specialists.
