Rootkit ZUP

 #4003  by EP_X0FF
 Wed Dec 15, 2010 6:03 am
Thanks goes to Jaxryley for the dropper. Comes together with TDL4 from the same drop zone.

Named ZUP because of PDB strings found inside
c:\p\c\objfre_wxp_x86\i386\zup.pdb
and file naming

Dropper contains two additional modules
http://www.virustotal.com/file-scan/rep ... 1292277861

1. Payload C&C dll. Registers as service and interacts with rootkit driver

http://www.virustotal.com/file-scan/rep ... 1292391433
zzup zup zup c:\windows\system32\zup.dll
Strings from unpacked C&C library.
