Today I was confronted with malware and here are my results:
HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Image File Execution Options\conime.exe\wcoredk.exe
netstat –aon -> showed the 126.96.36.199:32132 as destination
While it runs, wcoredk.exe ‘kills’ Sysinternals Tcpview/Nirsoft CurrPorts and Sysinternals Process Explorer. –> Finally, ANVIR helped me out!!!
Furthermore it disables ‘Show hidden files and folders’ shortly after it was set, and despite it had an PID it hasn’t an process name so it wasn’t listed under any task manager.
So looks like it is/was an Rootkit dressed Trojan/Mailer.
But the AV vendors are working onto it now:
1.) McAfee Labs
McAfee Labs – Beaverton
Current Scan Engine Version:5400.1158
Current DAT Version:5896.0000
