Troj/DwnLdr-KLB is a Trojan that propagates via an infected PowerPoint presentation document titled 'Will the world end in 2012?'. The malicious file includes Visual Basic macro code that downloads an executable file called 'VBA[X].exe', where [X] is a random capital letter. This sample needs the computer user to enable macros. Macros are generated to create a genuine Windows PE file (Portable Executable) from arrays of single bytes. The EXE file that is extracted is a dropper. It extracts another Windows PE file which downloads a picture of an owl, then contacts a command and control server. It is produced to distribute another payload that will be renamed as 'Wmupdate.exe', but does not send any commands from the command-and-control server to retrieve this payload. Computer users should be careful with documents they are sent from random sources and never enable macros in documents they download or receive as email attachments.
