[QUOTE="cruelsister, post: 1016680, member: 7463"] [MEDIA=youtube]kOrDPisiE4M[/MEDIA] A view of some of the mechanisms by which Malware Droppers work: 1). Unlike a Malware Downloader which needs to network access to connect to a server to acquire a malicious payload, in a Dropper the payload is obfuscated within the Dropper itself and then unpacked and moved onto the target drive. I've used 7zip to simulate this unpacking as it parallels what actually occurs. 2). Program Data is a preferred place for a Dropper to unpack the payload as it is by Default a Hidden Directory. This makes it more difficult for a malicious file to be spotted; important for malware such as this (termed a Persistent Dropper) as the malware is to remain on the system to be activated later through a Scheduled Task. 3). The inclusion of a routine to deactivate UAC is almost a given for malware droppers. [/QUOTE]
