Blackhole which hosts this dropper was generous. There are actually few Sirefef droppers, one from it pretty fresh (see attach). https://www.virustotal.com/file/9fe5b66 ... /analysis/

Same multistage installation + infection of system driver (seems infection code has been updated).

They are Sirefef and Fake AV's. Probably daily basis update.

Thnx for the sample, there are new features in this sample. VFS folder $NtUninstall%u$ is not reparse point anymore and its redirected to \SystemRoot\System32\config so user actually sees fake content also it now logs your search history into file named "oemid" in VFS folder. Definitely useful sample thnx!
